+{: #v1-1-0}
+
+This Calcite release makes it possible to exploit physical properties
+of relational expressions to produce more efficient plans, introducing
+collation and distribution as traits, `Exchange` relational operator,
+and several new forms of metadata.
+
+We add experimental support for streaming SQL.
+
+This release drops support for JDK 1.6; Calcite now requires 1.7 or
+later.
+
+We have introduced static `create` methods for many sub-classes of
+`RelNode`. We strongly suggest that you use these rather than
+calling constructors directly.

+
+API changes
+
+* [<a href="https://issues.apache.org/jira/browse/CALCITE-106">CALCITE-106</a>]
+ Make `Schema` and `Table` SPIs simpler to implement, and make them
+ re-usable across connections
+ (**This is a breaking change**.)
+* Make it easier to define sub-classes of rule operands. The new class
+ `RelOptRuleOperandChildren` contains the children of an operand and
+ the policy for dealing with them. Existing rules now use the new
+ methods to construct operands: `operand()`, `leaf()`, `any()`, `none()`,
+ `unordered()`. The previous methods are now deprecated and will be
+ removed before 0.4.18. (**This is a breaking change**.)
+* [<a href="https://issues.apache.org/jira/browse/CALCITE-101">CALCITE-101</a>]
+ Enable phased access to the Optiq engine
+* List-handling methods in `Util`: add methods `skipLast`, `last`, `skip`;
+ remove `subList`, `butLast`.
+* Convert `SqlIdentifier.names` from `String[]` to `ImmutableList<String>`.
+* Rename `OptiqAssert.assertThat()` to `that()`, to avoid clash with junit's
+ `Assert.assertThat()`.
+* Usability improvements for `RelDataTypeFactory.FieldInfoBuilder`. It
+ now has a type-factory, so you can just call `build()`.
+* Rework `HepProgramBuilder` into a fluent API.
+* [<a href="https://issues.apache.org/jira/browse/CALCITE-105">CALCITE-105</a>]
+ Externalize RelNode to and from JSON
+
+Tuning
+
+* If `EnumerableAggregateRel` has no aggregate functions, generate a
+ call to `Enumerable.distinct()`, thereby saving the effort of
+ building trivial accumulators.
+* Default rule set now does not introduce `CalcRel` until a later phase
+ of planning. This reduces the number of trivial projects and calcs
+ created, merged, and elimated.
+* Reduce the amount of time spent creating record types that
+ already exist.
+* More efficient implementation of `Util.isDistinct` for small lists.
+* When an internal record has 0 fields, rather than generating a
+ synthetic class and lots of instances that are all the same, use the
+ new `Unit` class, which is a singleton.
+* To take advantage of asymmetric hash join added recently in linq4j,
+ tweak cost of `EnumerableJoinRel` so that join is cheaper if the
+ larger input is on the left, and more expensive if it is a cartesian
+ product.
+* [<a href="https://issues.apache.org/jira/browse/CALCITE-70">CALCITE-70</a>]
+ Joins seem to be very expensive in memory
+* Make planning process more efficient by not sorting the list of
+ matched rules each cycle. It is sorted if tracing is enabled;
+ otherwise we scan to find the most important element. For this list,
+ replace `LinkedList` with `ChunkList`, which has an O(1) remove and add,
+ a fast O(n) get, and fast scan.
+
+Other
+
+* [<a href="https://issues.apache.org/jira/browse/CALCITE-87">CALCITE-87</a>]
+ Constant folding
+ * Rules for constant-expression reduction, and to simplify/eliminate
+ `VALUES` operator.
+* Graph algorithms: Implement breadth-first iterator and cycle-detector.
+* Fix bug in planner which occurred when two `RelNode`s have identical
+ digest but different row-type.
+* Fix link to optiq-csv tutorial.
+* Fix bugs in `RemoveTrivialProjectRule.strip`, `JdbcProjectRel.implement`
+ and `SortRel.computeSelfCost`.
+* Reformat code, and remove `@author` tags.
+* Upgrade to eigenbase-xom-1.3.4, eigenbase-properties-1.1.4,
+ eigenbase-resgen-1.3.6.
+* Upgrade to linq4j-0.1.12.
+* [<a href="https://issues.apache.org/jira/browse/CALCITE-97">CALCITE-97</a>]
+ Correlated EXISTS
+* Fix a bug in `VolcanoCost`.
+* Add class `FoodMartQuerySet`, that contains the 6,700 foodmart queries.
+* Fix factory class names in `UnregisteredDriver`
+* [<a href="https://issues.apache.org/jira/browse/CALCITE-96">CALCITE-96</a>]
+ LIMIT against a table in a clone schema causes UnsupportedOperationException
+* Disable spark module by default.
+* Allow `CloneSchema` to be specified in terms of url, driver, user,
+ password; not just dataSource.
+* Wrap internal error in `SQLException`.

+ condition
+* [<a href="https://issues.apache.org/jira/browse/CALCITE-74">CALCITE-74</a>]
+ JOIN ... USING fails in 3-way join with UnsupportedOperationException.
+* [<a href="https://issues.apache.org/jira/browse/CALCITE-65">CALCITE-65</a>]
+ Fix issues in the JDBC driver, and in particular to DatabaseMetaData methods,
+ to make Squirrel-SQL run better.
+* Fix JDBC column, table, schema names for when the table is not in a schema of
+ depth 1.
+* [<a href="https://issues.apache.org/jira/browse/CALCITE-85">CALCITE-85</a>]
+ Adding a table to the root schema causes breakage in OptiqPrepareImpl
+* [<a href="https://issues.apache.org/jira/browse/CALCITE-84">CALCITE-84</a>]
+ Extract Optiq's JDBC driver as a new JDBC driver framework, Avatica.
+ Other projects can use this to implement a JDBC driver by implementing
+ just a few methods. If you wish to use Optiq's JDBC driver, you will
+ now need to include optiq-avatica.jar in addition to optiq-core.jar.
+ Avatica does not depend on anything besides the standard Java library.
+* Support for parameters in PreparedStatement.
+* First steps in recognizing complex materializations. Internally we introduce a
+ concept called a "star table", virtual table composed of real tables joined
+ together via many-to-one relationships. The queries that define
+ materializations and end-user queries are canonized in terms of star tables.
+ Matching (not done yet) will then be a matter of looking for sort, groupBy,
+ project. It is not yet possible to define a star in an Optiq model file.
+* Add section to <a href="howto.md">HOWTO</a> on implementing adapters.
+* Fix data type conversions when creating a clone table in memory.
+* Fix how strings are escaped in JsonBuilder.
+* Test suite now depends on an embedded hsqldb database, so you can run
+ <code>mvn test</code> right after pulling from git. You can instead use a
+ MySQL database if you specify '-Dcalcite.test.db=mysql', but you need to
+ manually populate it.
+* Fix a planner issue which occurs when the left and right children of join are
+ the same relational expression, caused by a self-join query.
+* [<a href="https://issues.apache.org/jira/browse/CALCITE-76">CALCITE-76</a>]
+ Precedence of the item operator, <code>map[index]</code>; remove the space
+ before '[' when converting parse tree to string.
+* Allow <code>CAST(expression AS ANY)</code>, and fix an issue with the ANY type
+ and NULL values.
+* Handle null timestamps and dates coming out of JDBC adapter.
+* Add <code>jdbcDriver</code> attribute to JDBC schema in model, for drivers
+ that do not auto-register.
+* Allow join rules to match any subclass of JoinRelBase.
+* Push projects, filters and sorts down to MongoDB. (Fixes

-# Calcite HOWTO
-
-Here's some miscellaneous documentation about using Calcite and its various
-adapters.
-
-## Building from a source distribution
-
-Prerequisites are maven (3.2.1 or later)
-and Java (JDK 1.7 or later, 1.8 preferred) on your path.
-
-Unpack the source distribution `.tar.gz` or `.zip` file,
-`cd` to the root directory of the unpacked source,
-then build using maven:
-
-```bash
-$ tar xvfz calcite-1.3.0-incubating-source.tar.gz
-$ cd calcite-1.3.0-incubating
-$ mvn install
-```
-
-[Running tests](howto.md#running-tests) describes how to run more or fewer
-tests.
-
-## Building from git
-
-Prerequisites are git, maven (3.2.1 or later)
-and Java (JDK 1.7 or later, 1.8 preferred) on your path.
-
-Create a local copy of the github repository,
-`cd` to its root directory,
-then build using maven:
-
-```bash
-$ git clone git://github.com/apache/incubator-calcite.git
-$ cd incubator-calcite
-$ mvn install
-```
-
-[Running tests](howto.md#running-tests) describes how to run more or fewer
-tests.
-
-## Running tests
-
-The test suite will run by default when you build, unless you specify
-`-DskipTests`:
-
-```bash
-$ mvn clean # Note: mvn clean install does not work, use mvn clean && mvn install
-$ mvn -DskipTests install
-```
-
-There are other options that control which tests are run, and in what
-environment, as follows.
-
-* `-Dcalcite.test.db=DB` (where db is `h2`, `hsqldb`, `mysql`, or `postgresql`) allows you
- to change the JDBC data source for the test suite. Calcite's test
- suite requires a JDBC data source populated with the foodmart data
- set.
- * `hsqldb`, the default, uses an in-memory hsqldb database.
- * all others access test virtual machine (see [integration tests](howto.md#running-integration-tests) below)
- `mysql` and `postgresql` might be somewhat faster than hsqldb, but you need to populate it (i.e. provision a VM).
-* `-Dcalcite.debug` prints extra debugging information to stdout.
-* `-Dcalcite.test.slow` enables tests that take longer to execute. For
- example, there are tests that create virtual TPC-H and TPC-DS schemas
- in-memory and run tests from those benchmarks.
-* `-Dcalcite.test.splunk=true` enables tests that run against Splunk.
- Splunk must be installed and running.
-
-## Running integration tests
-
-For testing Calcite's external adapters, a test virtual machine should be used.
-The VM includes H2, HSQLDB, MySQL, MongoDB, and PostgreSQL.
-
-Test VM requires 5GiB of disk space and it takes 30 minutes to build.
-
-Note: you can use [calcite-test-dataset](https://github.com/vlsi/calcite-test-dataset)
- to populate your own database, however it is recommended to use test VM so the test environment can be reproduced.
-
-### VM preparation
-
-0) Install dependencies: [Vagrant](https://www.vagrantup.com/) and [VirtualBox](https://www.virtualbox.org/)
-
-1) Clone https://github.com/vlsi/calcite-test-dataset.git at the same level as calcite repository.
-For instance:
-```bash
-code
- +-- calcite
- +-- calcite-test-dataset
-```
-
-Note: integration tests search for ../calcite-test-dataset or ../../calcite-test-dataset.
- You can specify full path via calcite.test.dataset system property.
-
-2) Build and start the VM:
-```bash
-cd calcite-test-dataset && mvn install
-```
-
-### VM management
-
-Test VM is provisioned by Vagrant, so regular Vagrant `vagrant up` and `vagrant halt` should be used to start and stop the VM.
-The connection strings for different databases are listed in [calcite-test-dataset](https://github.com/vlsi/calcite-test-dataset) readme.
-
-### Suggested test flow
-
-Note: test VM should be started before you launch integration tests. Calcite itself does not start/stop the VM.
-
-Command line:
-* Executing regular unit tests (does not require external data): no change. `mvn test` or `mvn install`.
-* Executing all tests, for all the DBs: `mvn verify -Pit`. `it` stands for "integration-test". `mvn install -Pit` works as well.
-* Executing just tests for external DBs, excluding unit tests: `mvn -Dtest=foo -DfailIfNoTests=false -Pit verify`
-* Executing just MongoDB tests: `cd mongo; mvn verify -Pit`
-
-From within IDE:
-* Executing regular unit tests: no change.
-* Executing MongoDB tests: run `MongoAdapterIT.java` as usual (no additional properties are required)
-* Executing MySQL tests: run `JdbcTest` and `JdbcAdapterTest` with setting `-Dcalcite.test.db=mysql`
-* Executing PostgreSQL tests: run `JdbcTest` and `JdbcAdapterTest` with setting `-Dcalcite.test.db=postgresql`
-
-### Integration tests technical details
-
-Tests with external data are executed at maven's integration-test phase.
-We do not currently use pre-integration-test/post-integration-test, however we could use that in future.
-The verification of build pass/failure is performed at verify phase.
-Integration tests should be named `...IT.java`, so they are not picked up on unit test execution.
-
-## Contributing
-
-We welcome contributions.
-
-If you are planning to make a large contribution, talk to us first! It
-helps to agree on the general approach. Log a
-[JIRA case](https://issues.apache.org/jira/browse/CALCITE) for your
-proposed feature or start a discussion on the dev list.
-
-Fork the github repository, and create a branch for your feature.
-
-Develop your feature and test cases, and make sure that `mvn
-install` succeeds. (Run extra tests if your change warrants it.)
-
-Commit your change to your branch, and use a comment that starts with
-the JIRA case number, like this:
-
-```
-[CALCITE-345] AssertionError in RexToLixTranslator comparing to date literal
-```
-
-If your change had multiple commits, use `git rebase -i master` to
-combine them into a single commit, and to bring your code up to date
-with the latest on the main line.
-
-Then push your commit(s) to github, and create a pull request from
-your branch to the incubator-calcite master branch. Update the JIRA case
-to reference your pull request, and a committer will review your
-changes.
-
-## Getting started
-
-Calcite is a community, so the first step to joining the project is to introduce yourself.
-Join the [developers list](http://mail-archives.apache.org/mod_mbox/incubator-calcite-dev/)
-and send an email.
-
-If you have the chance to attend a [meetup](http://www.meetup.com/Apache-Calcite/),
-or meet [members of the community](http://calcite.incubator.apache.org/team-list.html)
-at a conference, that's also great.
-
-Choose an initial task to work on. It should be something really simple,
-such as a bug fix or a [Jira task that we have labeled
-"newbie"](https://issues.apache.org/jira/issues/?jql=labels%20%3D%20newbie%20%26%20project%20%3D%20Calcite%20%26%20status%20%3D%20Open).
-Follow the [contributing guidelines](#contributing) to get your change committed.
-
-After you have made several useful contributions we may
-[invite you to become a committer](https://community.apache.org/contributors/).
-We value all contributions that help to build a vibrant community, not just code.
-You can contribute by testing the code, helping verify a release,
-writing documentation or the web site,
-or just by answering questions on the list.
-
-## Tracing
-
-To enable tracing, add the following flags to the java command line:
-
-```
--Dcalcite.debug=true -Djava.util.logging.config.file=core/src/test/resources/logging.properties
-```
-
-The first flag causes Calcite to print the Java code it generates
-(to execute queries) to stdout. It is especially useful if you are debugging
-mysterious problems like this:
-
-```
-Exception in thread "main" java.lang.ClassCastException: Integer cannot be cast to Long
- at Baz$1$1.current(Unknown Source)
-```
-
-The second flag specifies a config file for
-the <a href="http://docs.oracle.com/javase/7/docs/api/java/util/logging/package-summary.html">java.util.logging</a>
-framework. Put the following into core/src/test/resources/logging.properties:
-
-```properties
-handlers= java.util.logging.ConsoleHandler
-.level= INFO
-org.apache.calcite.plan.RelOptPlanner.level=FINER
-java.util.logging.ConsoleHandler.level=ALL
-```
-
-The line `org.apache.calcite.plan.RelOptPlanner.level=FINER` tells the planner to produce
-fairly verbose output. You can modify the file to enable other loggers, or to change levels.
-For instance, if you change `FINER` to `FINEST` the planner will give you an account of the
-planning process so detailed that it might fill up your hard drive.

-First, download and install Calcite,
-and <a href="http://www.mongodb.org/downloads">install MongoDB</a>.
-
-Note: you can use MongoDB from integration test virtual machine above.
-
-Import MongoDB's zipcode data set into MongoDB:
-
-```bash
-$ curl -o /tmp/zips.json http://media.mongodb.org/zips.json
-$ mongoimport --db test --collection zips --file /tmp/zips.json
-Tue Jun 4 16:24:14.190 check 9 29470
-Tue Jun 4 16:24:14.469 imported 29470 objects
-```
-
-Log into MongoDB to check it's there:
-
-```bash
-$ mongo
-MongoDB shell version: 2.4.3
-connecting to: test
-> db.zips.find().limit(3)
-{ "city" : "ACMAR", "loc" : [ -86.51557, 33.584132 ], "pop" : 6055, "state" : "AL", "_id" : "35004" }
-{ "city" : "ADAMSVILLE", "loc" : [ -86.959727, 33.588437 ], "pop" : 10616, "state" : "AL", "_id" : "35005" }
-{ "city" : "ADGER", "loc" : [ -87.167455, 33.434277 ], "pop" : 3205, "state" : "AL", "_id" : "35006" }
-> exit
-bye
-```
-
-Connect using the
-<a href="https://github.com/apache/incubator-calcite/blob/master/mongodb/src/test/resources/mongo-zips-model.json">mongo-zips-model.json</a>
-Calcite model:

-## Splunk adapter
-
-To run the test suite and sample queries against Splunk,
-load Splunk's `tutorialdata.zip` data set as described in
-<a href="http://docs.splunk.com/Documentation/Splunk/6.0.2/PivotTutorial/GetthetutorialdataintoSplunk">the Splunk tutorial</a>.
-
-(This step is optional, but it provides some interesting data for the sample
-queries. It is also necessary if you intend to run the test suite, using
-`-Dcalcite.test.splunk=true`.)
-
-## Implementing an adapter
-
-New adapters can be created by implementing `CalcitePrepare.Context`:
-
-```java
-import org.apache.calcite.adapter.java.JavaTypeFactory;
-import org.apache.calcite.jdbc.CalcitePrepare;
-import org.apache.calcite.jdbc.CalciteRootSchema;
-
-public class AdapterContext implements CalcitePrepare.Context {
- @Override
- public JavaTypeFactory getTypeFactory() {
- // adapter implementation
- return typeFactory;
- }
-
- @Override
- public CalciteRootSchema getRootSchema() {
- // adapter implementation
- return rootSchema;
- }
-}
-```
-
-### Testing adapter in Java
-
-The example below shows how SQL query can be submitted to
-`CalcitePrepare` with a custom context (`AdapterContext` in this
-case). Calcite prepares and implements the query execution, using the
-resources provided by the `Context`. `CalcitePrepare.PrepareResult`
-provides access to the underlying enumerable and methods for
-enumeration. The enumerable itself can naturally be some adapter
-specific implementation.
-
-```java
-import org.apache.calcite.jdbc.CalcitePrepare;
-import org.apache.calcite.prepare.CalcitePrepareImpl;
-import org.junit.Test;
-
-public class AdapterContextTest {
- @Test
- public void testSelectAllFromTable() {
- AdapterContext ctx = new AdapterContext();
- String sql = "SELECT * FROM TABLENAME";
- Class elementType = Object[].class;
- CalcitePrepare.PrepareResult<Object> prepared =
- new CalcitePrepareImpl().prepareSql(ctx, sql, null, elementType, -1);
- Object enumerable = prepared.getExecutable();
- // etc.
- }
-}
-```
-
-### JavaTypeFactory
-
-When Calcite compares types (instances of `RelDataType`), it requires them to be the same
-object. If there are two distinct type instances that refer to the
-same Java type, Calcite may fail to recognize that they match. It is
-recommended to:
-* Use a single instance of `JavaTypeFactory` within the calcite context;
-* Store the types so that the same object is always returned for the same type.
-
-## Set up PGP signing keys (for Calcite committers)
-
-Follow instructions at http://www.apache.org/dev/release-signing to
-create a key pair. (On Mac OS X, I did `brew install gpg` and `gpg
---gen-key`.)
-
-Add your public key to the `KEYS` file by following instructions in
-the `KEYS` file.
-
-## Making a snapshot (for Calcite committers)
-
-Before you start:
-* Set up signing keys as described above.
-* Make sure you are using JDK 1.7 (not 1.8).
-* Make sure build and tests succeed with `-Dcalcite.test.db=hsqldb` (the default)
-
-```bash
-# Set passphrase variable without putting it into shell history
-read -s GPG_PASSPHRASE
-
-# Make sure that there are no junk files in the sandbox
-git clean -xn
-mvn clean
-
-mvn -Papache-release -Dgpg.passphrase=${GPG_PASSPHRASE} install
-```
-
-When the dry-run has succeeded, change `install` to `deploy`.
-
-## Making a release (for Calcite committers)
-
-Before you start:
-* Set up signing keys as described above.
-* Make sure you are using JDK 1.7 (not 1.8).
-* Check that `README`, `README.md` and `doc/howto.md` have the correct version number.
-* Set `version.major` and `version.minor` in `pom.xml`.
-* Make sure build and tests succeed, including with
- -Dcalcite.test.db={mysql,hsqldb}, -Dcalcite.test.slow=true,
- -Dcalcite.test.mongodb=true, -Dcalcite.test.splunk=true.
-* Trigger a
- <a href="https://scan.coverity.com/projects/2966">Coverity scan</a>
- by merging the latest code into the `julianhyde/coverity_scan` branch,
- and when it completes, make sure that there are no important issues.
-* Make sure that
- <a href="https://issues.apache.org/jira/issues/?jql=project%20%3D%20CALCITE%20AND%20status%20%3D%20Resolved%20and%20fixVersion%20is%20null">
- every "resolved" JIRA case</a> (including duplicates) has
- a fix version assigned (most likely the version we are
- just about to release)
-
-Create a release branch named after the release, e.g. `branch-1.1`, and push it to Apache.
-
-```bash
-$ git checkout -b branch-X.Y
-$ git push -u origin branch-X.Y
-```
-
-We will use the branch for the entire the release process. Meanwhile,
-we do not allow commits to the master branch. After the release is
-final, we can use `git merge --ff-only` to append the changes on the
-release branch onto the master branch. (Apache does not allow reverts
-to the master branch, which makes it difficult to clean up the kind of
-messy commits that inevitably happen while you are trying to finalize
-a release.)
-
-Now, set up your environment and do a dry run. The dry run will not
-commit any changes back to git and gives you the opportunity to verify
-that the release process will complete as expected.
-
-If any of the steps fail, clean up (see below), fix the problem, and
-start again from the top.
-
-```bash
-# Set passphrase variable without putting it into shell history
-read -s GPG_PASSPHRASE
-
-# Make sure that there are no junk files in the sandbox
-git clean -xn
-mvn clean
-
-# Do a dry run of the release:prepare step, which sets version numbers.
-mvn -DdryRun=true -DskipTests -DreleaseVersion=X.Y.Z-incubating -DdevelopmentVersion=X.Y.Z+1-incubating-SNAPSHOT -Papache-release -Darguments="-Dgpg.passphrase=${GPG_PASSPHRASE}" release:prepare 2>&1 | tee /tmp/prepare-dry.log
-```
-
-Check the artifacts:
-* In the `target` directory should be these 8 files, among others:
- * apache-calcite-X.Y.Z-incubating-src.tar.gz
- * apache-calcite-X.Y.Z-incubating-src.tar.gz.asc
- * apache-calcite-X.Y.Z-incubating-src.tar.gz.md5
- * apache-calcite-X.Y.Z-incubating-src.tar.gz.sha1
- * apache-calcite-X.Y.Z-incubating-src.zip
- * apache-calcite-X.Y.Z-incubating-src.zip.asc
- * apache-calcite-X.Y.Z-incubating-src.zip.md5
- * apache-calcite-X.Y.Z-incubating-src.zip.sha1
-* Note that the file names start `apache-calcite-` and include
- `incubating` in the version.
-* In the two source distros `.tar.gz` and `.zip` (currently there is
- no binary distro), check that all files belong to a directory called
- `apache-calcite-X.Y.Z-incubating-src`.
-* That directory must contain files `DISCLAIMER`, `NOTICE`, `LICENSE`,
- `README`, `README.md`
- * Check that the version in `README` is correct
-* In each .jar (for example
- `core/target/calcite-core-X.Y.Z-incubating.jar` and
- `mongodb/target/calcite-mongodb-X.Y.Z-incubating-sources.jar`), check
- that the `META-INF` directory contains `DEPENDENCIES`, `LICENSE`,
- `NOTICE` and `git.properties`
-* In each .jar, check that `org-apache-calcite-jdbc.properties` is
- present and does not contain un-substituted `${...}` variables
-* Check PGP, per https://httpd.apache.org/dev/verification.html
-
-Now, remove the `-DdryRun` flag and run the release for real.
-
-```bash
-# Prepare sets the version numbers, creates a tag, and pushes it to git.
-mvn -DdryRun=false -DskipTests -DreleaseVersion=X.Y.Z-incubating -DdevelopmentVersion=X.Y.Z+1-incubating-SNAPSHOT -Papache-release -Darguments="-Dgpg.passphrase=${GPG_PASSPHRASE}" release:prepare 2>&1 | tee /tmp/prepare.log
-
-# Perform checks out the tagged version, builds, and deploys to the staging repository
-mvn -DskipTests -Papache-release -Darguments="-Dgpg.passphrase=${GPG_PASSPHRASE}" release:perform 2>&1 | tee /tmp/perform.log
-```
-
-Verify the staged artifacts in the Nexus repository:
-* Go to https://repository.apache.org/
-* Under `Build Promotion`, click `Staging Repositories`
-* In the `Staging Repositories` tab there should be a line with profile `org.apache.calcite`
-* Navigate through the artifact tree and make sure the .jar, .pom, .asc files are present
-* Check the box on in the first column of the row,
- and press the 'Close' button to publish the repository at
- https://repository.apache.org/content/repositories/orgapachecalcite-1000
- (or a similar URL)
-
-Upload the artifacts via subversion to a staging area,
-https://dist.apache.org/repos/dist/dev/incubator/calcite/apache-calcite-X.Y.Z-incubating-rcN:
-
-```bash
-# Create a subversion workspace, if you haven't already
-mkdir -p ~/dist/dev
-pushd ~/dist/dev
-svn co https://dist.apache.org/repos/dist/dev/incubator/calcite
-popd

-# Lattice
-
-A lattice is a framework for creating and populating materialized views,
-and for recognizing that a materialized view can be used to solve a
-particular query.
-
-A lattice represents a star (or snowflake) schema, not a general
-schema. In particular, all relationships must be many-to-one, heading
-from a fact table at the center of the star.
-
-The name derives from the mathematics: a
-<a href="http://en.wikipedia.org/wiki/Lattice_(order)">lattice</a>
-is a
-<a href="http://en.wikipedia.org/wiki/Partially_ordered_set">partially
-ordered set</a> where any two elements have a unique greatest lower
-bound and least upper bound.
-
-[<a href="#user-content-ref-hru96">HRU96</a>] observed that the set of possible
-materializations of a data cube forms a lattice, and presented an
-algorithm to choose a good set of materializations. Calcite's
-recommendation algorithm is derived from this.
-
-The lattice definition uses a SQL statement to represent the star. SQL
-is a useful short-hand to represent several tables joined together,
-and assigning aliases to the column names (it more convenient than
-inventing a new language to represent relationships, join conditions
-and cardinalities).
-
-Unlike regular SQL, order is important. If you put A before B in the
-FROM clause, and make a join between A and B, you are saying that
-there is a many-to-one foreign key relationship from A to B. (E.g. in
-the example lattice, the Sales fact table occurs before the Time
-dimension table, and before the Product dimension table. The Product
-dimension table occurs before the ProductClass outer dimension table,
-further down an arm of a snowflake.)
-
-A lattice implies constraints. In the A to B relationship, there is a
-foreign key on A (i.e. every value of A's foreign key has a
-corresponding value in B's key), and a unique key on B (i.e. no key
-value occurs more than once). These constraints are really important,
-because it allows the planner to remove joins to tables whose columns
-are not being used, and know that the query results will not change.
-
-Calcite does not check these constraints. If they are violated,
-Calcite will return wrong results.
-
-A lattice is a big, virtual join view. It is not materialized (it
-would be several times larger than the star schema, because of
-denormalization) and you probably wouldn't want to query it (far too
-many columns). So what is it useful for? As we said above, (a) the
-lattice declares some very useful primary and foreign key constraints,
-(b) it helps the query planner map user queries onto
-filter-join-aggregate materialized views (the most useful kind of
-materialized view for DW queries), (c) gives Calcite a framework
-within which to gather stats about data volumes and user queries, (d)
-allows Calcite to automatically design and populate materialized
-views.
-
-Most star schema models force you to choose whether a column is a
-dimension or a measure. In a lattice, every column is a dimension
-column. (That is, it can become one of the columns in the GROUP BY clause
-to query the star schema at a particular dimensionality). Any column
-can also be used in a measure; you define measures by giving the
-column and an aggregate function.
-
-If "unit_sales" tends to be used much more often as a measure rather
-than a dimension, that's fine. Calcite's algorithm should notice that
-it is rarely aggregated, and not be inclined to create tiles that
-aggregate on it. (By "should" I mean "could and one day will". The
-algorithm does not currently take query history into account when
-designing tiles.)
-
-But someone might want to know whether orders with fewer than 5 items
-were more or less profitable than orders with more than 100. All of a
-sudden, "unit_sales" has become a dimension. If there's virtually zero
-cost to declaring a column a dimension column, I figured let's make
-them all dimension columns.
-
-The model allows for a particular table to be used more than once,
-with a different table alias. You could use this to model say
-OrderDate and ShipDate, with two uses to the Time dimension table.
-
-Most SQL systems require that the column names in a view are unique.
-This is hard to achieve in a lattice, because you often include
-primary and foreign key columns in a join. So Calcite lets you refer
-to columns in two ways. If the column is unique, you can use its name,
-["unit_sales"]. Whether or not it is unique in the lattice, it will be
-unique in its table, so you can use it qualified by its table alias.
-Examples:
-* ["sales", "unit_sales"]
-* ["ship_date", "time_id"]
-* ["order_date", "time_id"]
-
-A "tile" is a materialized table in a lattice, with a particular
-dimensionality. (What Kylin calls a "cuboid".) The "tiles" attribute
-of the <a href="model.json#lattice">lattice JSON element</a>
-defines an initial set of tiles to materialize.
-
-If you run the algorithm, you can omit the tiles attribute. Calcite
-will choose an initial set. If you include the tiles attribute, the
-algorithm will start with that list and then start finding other tiles
-that are complementary (i.e. "fill in the gaps" left by the initial
-tiles).

-# Calcite JSON model reference
-
-## Elements
-
-### Root
-
-```json
-{
- version: '1.0',
- defaultSchema: 'mongo',
- schemas: [ Schema... ]
-}
-```
-
-`version` (required string) must have value `1.0`.
-
-`defaultSchema` (optional string). If specified, it is
-the name (case-sensitive) of a schema defined in this model, and will
-become the default schema for connections to Calcite that use this model.
-
-`schemas` (optional list of <a href="#schema">Schema</a> elements).
-
-### Schema
-
-Occurs within `root.schemas`.
-
-```json
-{
- name: 'foodmart',
- path: ['lib'],
- cache: true,
- materializations: [ Materialization... ]
-}
-```
-
-`name` (required string) is the name of the schema.
-
-`type` (optional string, default `map`) indicates sub-type. Values are:
-* `map` for <a href="#map-schema">Map Schema</a>
-* `custom` for <a href="#custom-schema">Custom Schema</a>
-* `jdbc` for <a href="#jdbc-schema">JDBC Schema</a>
-
-`path` (optional list) is the SQL path that is used to
-resolve functions used in this schema. If specified it must be a list,
-and each element of the list must be either a string or a list of
-strings. For example,
-
-```json
- path: [ ['usr', 'lib'], 'lib' ]
-```
-
-declares a path with two elements: the schema '/usr/lib' and the
-schema '/lib'. Most schemas are at the top level, so you can use a
-string.
-
-`materializations` (optional list of
-<a href="#materialization">Materialization</a>) defines the tables
-in this schema that are materializations of queries.
-
-`cache` (optional boolean, default true) tells Calcite whether to
-cache metadata (tables, functions and sub-schemas) generated
-by this schema.
-
-* If `false`, Calcite will go back to the schema each time it needs
- metadata, for example, each time it needs a list of tables in order to
- validate a query against the schema.
-
-* If `true`, Calcite will cache the metadata the first time it reads
- it. This can lead to better performance, especially if name-matching is
- case-insensitive.
-
-However, it also leads to the problem of cache staleness.
-A particular schema implementation can override the
-`Schema.contentsHaveChangedSince` method to tell Calcite
-when it should consider its cache to be out of date.
-
-Tables, functions and sub-schemas explicitly created in a schema are
-not affected by this caching mechanism. They always appear in the schema
-immediately, and are never flushed.
-
-### Map Schema
-
-Like base class <a href="#schema">Schema</a>, occurs within `root.schemas`.
-
-```json
-{
- name: 'foodmart',
- type: 'map',
- tables: [ Table... ],
- functions: [ Function... ]
-}
-```
-
-`name`, `type`, `path`, `cache`, `materializations` inherited from
-<a href="#schema">Schema</a>.
-
-`tables` (optional list of <a href="#table">Table</a> elements)
-defines the tables in this schema.
-
-`functions` (optional list of <a href="#function">Function</a> elements)
-defines the functions in this schema.
-
-### Custom Schema
-
-Like base class <a href="#schema">Schema</a>, occurs within `root.schemas`.

- operand: {
- host: 'localhost',
- database: 'test'
- }
-}
-```
-
-`name`, `type`, `path`, `cache`, `materializations` inherited from
-<a href="#schema">Schema</a>.
-
-`factory` (required string) is the name of the factory class for this
-schema. Must implement interface `org.apache.calcite.schema.SchemaFactory`
-and have a public default constructor.
-
-`operand` (optional map) contains attributes to be passed to the
-factory.
-
-### JDBC Schema
-
-Like base class <a href="#schema">Schema</a>, occurs within `root.schemas`.
-
-```json
-{
- name: 'foodmart',
- type: 'jdbc',
- jdbcDriver: TODO,
- jdbcUrl: TODO,
- jdbcUser: TODO,
- jdbcPassword: TODO,
- jdbcCatalog: TODO,
- jdbcSchema: TODO
-}
-```
-
-`name`, `type`, `path`, `cache`, `materializations` inherited from
-<a href="#schema">Schema</a>.
-
-`jdbcDriver` (optional string) is the name of the JDBC driver class. It not
-specified, uses whichever class the JDBC DriverManager chooses.
-
-`jdbcUrl` (optional string) is the JDBC connect string, for example
-"jdbc:mysql://localhost/foodmart".
-
-`jdbcUser` (optional string) is the JDBC user name.
-
-`jdbcPassword` (optional string) is the JDBC password.
-
-`jdbcCatalog` (optional string) is the name of the initial catalog in the JDBC
-data source.
-
-`jdbcSchema` (optional string) is the name of the initial schema in the JDBC
-data source.
-
-### Materialization
-
-Occurs within `root.schemas.materializations`.
-
-```json
-{
- view: 'V',
- table: 'T',
- sql: 'select deptno, count(*) as c, sum(sal) as s from emp group by deptno'
-}
-```
-
-`view` (optional string) TODO
-
-`table` (optional string) TODO
-
-`sql` (optional string, or list of strings that will be concatenated as a
- multi-line string) is the SQL definition of the materialization.
-
-### Table
-
-Occurs within `root.schemas.tables`.
-
-```json
-{
- name: 'sales_fact',
- columns: [ Column... ]
-}
-```
-
-`name` (required string) is the name of this table. Must be unique within the schema.
-
-`type` (optional string, default `custom`) indicates sub-type. Values are:
-* `custom` for <a href="#custom-table">Custom Table</a>
-* `view` for <a href="#view">View</a>
-
-`columns` (optional list of <a href="#column">Column</a> elements)
-
-### View
-
-Like base class <a href="#table">Table</a>, occurs within `root.schemas.tables`.
-
-```json
-{
- name: 'female_emps',
- type: 'view',
- sql: "select * from emps where gender = 'F'",
- modifiable: true
-}
-```
-
-`name`, `type`, `columns` inherited from <a href="#table">Table</a>.
-
-`sql` (required string, or list of strings that will be concatenated as a
- multi-line string) is the SQL definition of the view.
-
-`path` (optional list) is the SQL path to resolve the query. If not
-specified, defaults to the current schema.
-
-`modifiable` (optional boolean) is whether the view is modifiable.
-If null or not specified, Calcite deduces whether the view is modifiable.
-
-A view is modifiable if contains only SELECT, FROM, WHERE (no JOIN, aggregation
-or sub-queries) and every column:
-* is specified once in the SELECT clause; or
-* occurs in the WHERE clause with a `column = literal` predicate; or
-* is nullable.
-
-The second clause allows Calcite to automatically provide the correct value for
-hidden columns. It is useful in multi-tenant environments, where the `tenantId`
-column is hidden, mandatory (NOT NULL), and has a constant value for a
-particular view.
-
-Errors regarding modifiable views:
-* If a view is marked `modifiable: true` and is not modifiable, Calcite throws
- an error while reading the schema.
-* If you submit an INSERT, UPDATE or UPSERT command to a non-modifiable view,
- Calcite throws an error when validating the statement.
-* If a DML statement creates a row that would not appear in the view
- (for example, a row in `female_emps`, above, with `gender = 'M'`),
- Calcite throws an error when executing the statement.
-
-### Custom Table
-
-Like base class <a href="#table">Table</a>, occurs within `root.schemas.tables`.
-
-```json
-{
- name: 'female_emps',
- type: 'custom',
- factory: 'TODO',
- operand: {
- todo: 'TODO'
- }
-}
-```
-
-`name`, `type`, `columns` inherited from <a href="#table">Table</a>.
-
-`factory` (required string) is the name of the factory class for this
-table. Must implement interface `org.apache.calcite.schema.TableFactory`
-and have a public default constructor.
-
-`operand` (optional map) contains attributes to be passed to the
-factory.
-
-### Column
-
-Occurs within `root.schemas.tables.columns`.

-
-### Lattice
-
-Occurs within `root.schemas.lattices`.
-
-```json

- ],
- auto: false,
- algorithm: true,
- algorithmMaxMillis: 10000,
- rowCountEstimate: 86837,
- defaultMeasures: [ {
- agg: 'count'

- tiles: [ {
- dimensions: [ 'the_year', ['t', 'quarter'] ],
- measures: [ {
- agg: 'sum',
- args: 'unit_sales'

-```
-
-See also: <a href="lattice.md">Lattices</a>.
-
-### Tile

-
-In *merge*, at least one of the WHEN MATCHED and WHEN NOT MATCHED clauses must
-be present.
-
-In *orderItem*, if *expression* is a positive integer *n*, it denotes
-the <em>n</em>th item in the SELECT clause.
-
-An aggregate query is a query that contains a GROUP BY or a HAVING
-clause, or aggregate functions in the SELECT clause. In the SELECT,
-HAVING and ORDER BY clauses of an aggregate query, all expressions
-must be constant within the current group (that is, grouping constants
-as defined by the GROUP BY clause, or constants), or aggregate
-functions, or a combination of constants and aggregate
-functions. Aggregate and grouping functions may only appear in an
-aggregate query, and only in a SELECT, HAVING or ORDER BY clause.
-
-A scalar sub-query is a sub-query used as an expression. It can occur
-in most places where an expression can occur (such as the SELECT
-clause, WHERE clause, or as an argument to an aggregate
-function). If the sub-query returns no rows, the value is NULL; if it
-returns more than one row, it is an error.
-
-A sub-query can occur in the FROM clause of a query and also in IN
-and EXISTS expressions. A sub-query that occurs in IN and
-EXISTS expressions may be correlated; that is, refer to tables in
-the FROM clause of an enclosing query.
-
-## Identifiers
-
-Identifiers are the names of tables, columns and other metadata
-elements used in a SQL query.
-
-Unquoted identifiers, such as emp, must start with a letter and can
-only contain letters, digits, and underscores. They are implicitly
-converted to upper case.
-
-Quoted identifiers, such as "Employee Name", start and end with
-double quotes. They may contain virtually any character, including
-spaces and other punctuation. If you wish to include a double quote
-in an identifier, use another double quote to escape it, like this:
-"An employee called ""Fred""."
-
-In Calcite, matching identifiers to the name of the referenced object is
-case-sensitive. But remember that unquoted identifiers are implicitly
-converted to upper case before matching, and if the object it refers
-to was created using an unquoted identifier for its name, then its
-name will have been converted to upper case also.
-

-# Calcite SQL extensions for streaming
-
-## Introduction
-
-Streams are collections to records that flow continuously, and forever.
-Unlike tables, they are not typically stored on disk, but flow over the
-network and are held for short periods of time in memory.
-
-Streams complement tables because they represent what is happening in the
-present and future of the enterprise whereas tables represent the past.
-It is very common for a stream to be archived into a table.
-
-Like tables, you often want to query streams in a high-level language
-based on relational algebra, validated according to a schema, and optimized
-to take advantage of available resources and algorithms.
-
-Calcite's SQL is an extension to standard SQL, not another 'SQL-like' language.
-The distinction is important, for several reasons:
-* Streaming SQL is easy to learn for anyone who knows regular SQL.
-* The semantics are clear, because we aim to produce the same results on a
- stream as if the same data were in a table.
-* You can write queries that combine streams and tables (or the history of
- a stream, which is basically an in-memory table).
-* Lots of existing tools can generate standard SQL.
-
-## An example schema
-
-Our streaming SQL examples use the following schema:
-* `Orders (rowtime, productId, orderId, units)` - a stream and a table
-* `Products (rowtime, productId, name)` - a table
-* `Shipments (rowtime, orderId)` - a stream
-
-## A simple query
-
-Let's start with the simplest streaming query:
-
-```sql
-SELECT STREAM *
-FROM Orders;
-
- rowtime | productId | orderId | units
-----------+-----------+---------+-------
- 10:17:00 | 30 | 5 | 4
- 10:17:05 | 10 | 6 | 1
- 10:18:05 | 20 | 7 | 2
- 10:18:07 | 30 | 8 | 20
- 11:02:00 | 10 | 9 | 6
- 11:04:00 | 10 | 10 | 1
- 11:09:30 | 40 | 11 | 12
- 11:24:11 | 10 | 12 | 4
-```
-
-This query reads all columns and rows from the `Orders` stream.
-Like any streaming query, it never terminates. It outputs a record whenever
-a record arrives in `Orders`.
-
-Type `Control-C` to terminate the query.
-
-The `STREAM` keyword is the main extension in streaming SQL. It tells the
-system that you are interested in incoming orders, not existing ones. The query
-
-```sql
-SELECT *
-FROM Orders;
-
- rowtime | productId | orderId | units
-----------+-----------+---------+-------
- 08:30:00 | 10 | 1 | 3
- 08:45:10 | 20 | 2 | 1
- 09:12:21 | 10 | 3 | 10
- 09:27:44 | 30 | 4 | 2
-
-4 records returned.
-```
-
-is also valid, but will print out all existing orders and then terminate. We
-call it a *relational* query, as opposed to *streaming*. It has traditional
-SQL semantics.
-
-`Orders` is special, in that it has both a stream and a table. If you try to run
-a streaming query on a table, or a relational query on a stream, Calcite gives
-an error:
-
-```sql
-> SELECT * FROM Shipments;
-ERROR: Cannot convert stream 'SHIPMENTS' to a table
-
-> SELECT STREAM * FROM Products;
-ERROR: Cannot convert table 'PRODUCTS' to a stream
-```
-
-# Filtering rows
-
-Just as in regular SQL, you use a `WHERE` clause to filter rows:
-
-```sql
-SELECT STREAM *
-FROM Orders
-WHERE units > 3;
-
- rowtime | productId | orderId | units
-----------+-----------+---------+-------
- 10:17:00 | 30 | 5 | 4
- 10:18:07 | 30 | 8 | 20
- 11:02:00 | 10 | 9 | 6
- 11:09:30 | 40 | 11 | 12
- 11:24:11 | 10 | 12 | 4
-```
-
-# Projecting expressions
-
-Use expressions in the `SELECT` clause to choose which columns to return or
-compute expressions:
-
-```sql
-SELECT STREAM rowtime,
- 'An order for ' || units || ' '
- || CASE units WHEN 1 THEN 'unit' ELSE 'units' END
- || ' of product #' || productId AS description
-FROM Orders;
-
- rowtime | description
-----------+---------------------------------------
- 10:17:00 | An order for 4 units of product #30
- 10:17:05 | An order for 1 unit of product #10
- 10:18:05 | An order for 2 units of product #20
- 10:18:07 | An order for 20 units of product #30
- 11:02:00 | An order by 6 units of product #10
- 11:04:00 | An order by 1 unit of product #10
- 11:09:30 | An order for 12 units of product #40
- 11:24:11 | An order by 4 units of product #10
-```
-
-We recommend that you always include the `rowtime` column in the `SELECT`
-clause. Having a sorted timestamp in each stream and streaming query makes it
-possible to do advanced calculations later, such as `GROUP BY` and `JOIN`.
-
-# Tumbling windows
-
-There are several ways to compute aggregate functions on streams. The
-differences are:
-* How many rows come out for each row in?
-* Does each incoming value appear in one total, or more?
-* What defines the "window", the set of rows that contribute to a given output row?
-* Is the result a stream or a relation?
-
-First we'll look a *tumbling window*, which is defined by a streaming
-`GROUP BY`. Here is an example:
-
-```sql
-SELECT STREAM FLOOR(rowtime TO HOUR) AS rowtime,
- productId,
- COUNT(*) AS c,
- SUM(units) AS units
-FROM Orders
-GROUP BY FLOOR(rowtime TO HOUR), productId;
-
- rowtime | productId | c | units
-----------+-----------+---------+-------
- 10:00:00 | 30 | 2 | 24
- 10:00:00 | 10 | 1 | 1
- 10:00:00 | 20 | 1 | 7
- 11:00:00 | 10 | 3 | 11
- 11:00:00 | 40 | 1 | 12
-```
-
-The result is a stream. At 11 o'clock, Calcite emits a sub-total for every
-`productId` that had an order since 10 o'clock. At 12 o'clock, it will emit
-the orders that occurred between 11:00 and 12:00. Each input row contributes to
-only one output row.
-
-How did Calcite know that the 10:00:00 sub-totals were complete at 11:00:00,
-so that it could emit them? It knows that `rowtime` is increasing, and it knows
-that `FLOOR(rowtime TO HOUR)` is also increasing. So, once it has seen a row
-at or after 11:00:00, it will never see a row that will contribute to a 10:00:00
-total.
-
-A column or expression that is increasing or decreasing is said to be
-*monotonic*. Without a monotonic expression in the `GROUP BY` clause, Calcite is
-not able to make progress, and it will not allow the query:
-
-```sql
-> SELECT STREAM productId,
-> COUNT(*) AS c,
-> SUM(units) AS units
-> FROM Orders
-> GROUP BY productId;
-ERROR: Streaming aggregation requires at least one monotonic expression in GROUP BY clause
-```
-
-Monotonic columns need to be declared in the schema. The monotonicity is
-enforced when records enter the stream and assumed by queries that read from
-that stream. We recommend that you give each stream a timestamp column called
-`rowtime`, but you can declare others, `orderId`, for example.
-
-# Filtering after aggregation
-
-As in standard SQL, you can apply a `HAVING` clause to filter rows emitted by
-a streaming `GROUP BY`:
-
-```sql
-SELECT STREAM FLOOR(rowtime TO HOUR) AS rowtime,
- productId
-FROM Orders
-GROUP BY FLOOR(rowtime TO HOUR), productId
-HAVING COUNT(*) > 2 OR SUM(units) > 10;
-
- rowtime | productId
-----------+-----------
- 10:00:00 | 30
- 11:00:00 | 10
- 11:00:00 | 40
-```
-
-# Sub-queries, views and SQL's closure property
-
-The previous `HAVING` query can be expressed using a `WHERE` clause on a
-sub-query:
-
-```sql
-SELECT STREAM rowtime, productId
-FROM (
- SELECT FLOOR(rowtime TO HOUR) AS rowtime,
- productId,
- COUNT(*) AS c,
- SUM(units) AS su
- FROM Orders
- GROUP BY FLOOR(rowtime TO HOUR), productId)
-WHERE c > 2 OR su > 10;
-
- rowtime | productId
-----------+-----------
- 10:00:00 | 30
- 11:00:00 | 10
- 11:00:00 | 40
-```
-
-`HAVING` was introduced in the early days of SQL, when a way was needed to
-perform a filter *after* aggregation. (Recall that `WHERE` filters rows before
-they enter the `GROUP BY` clause.)
-
-Since then, SQL has become a mathematically closed language, which means that
-any operation you can perform on a table can also perform on a query.
-
-The *closure property* of SQL is extremely powerful. Not only does it render
-`HAVING` obsolete (or, at least, reduce it to syntactic sugar), it makes views
-possible:
-
-```sql
-CREATE VIEW HourlyOrderTotals (rowtime, productId, c, su) AS
- SELECT FLOOR(rowtime TO HOUR),
- productId,
- COUNT(*),
- SUM(units)
- FROM Orders
- GROUP BY FLOOR(rowtime TO HOUR), productId;
-
-SELECT STREAM rowtime, productId
-FROM HourlyOrderTotals
-WHERE c > 2 OR su > 10;
-
- rowtime | productId
-----------+-----------
- 10:00:00 | 30
- 11:00:00 | 10
- 11:00:00 | 40
-```
-
-Sub-queries in the `FROM` clause are sometimes referred to as "inline views",
-but really, nested queries are more fundamental. Views are just a convenient
-way to carve your SQL into manageable chunks.
-
-Many people find that nested queries and views are even more useful on streams
-than they are on relations. Streaming queries are pipelines of
-operators all running continuously, and often those pipelines get quite long.
-Nested queries and views help to express and manage those pipelines.
-
-And, by the way, a `WITH` clause can accomplish the same as a sub-query or
-a view:
-
-```sql
-WITH HourlyOrderTotals (rowtime, productId, c, su) AS (
- SELECT FLOOR(rowtime TO HOUR),
- productId,
- COUNT(*),
- SUM(units)
- FROM Orders
- GROUP BY FLOOR(rowtime TO HOUR), productId)
-SELECT STREAM rowtime, productId
-FROM HourlyOrderTotals
-WHERE c > 2 OR su > 10;
-
- rowtime | productId
-----------+-----------
- 10:00:00 | 30
- 11:00:00 | 10
- 11:00:00 | 40
-```
-
-## Converting between streams and relations
-
-Look back at the definition of the `HourlyOrderTotals` view.
-Is the view a stream or a relation?
-
-It does not contain the `STREAM` keyword, so it is a relation.
-However, it is a relation that can be converted into a stream.
-
-You can use it in both relational and streaming queries:
-
-```sql
-# A relation; will query the historic Orders table.
-# Returns the largest number of product #10 ever sold in one hour.
-SELECT max(su)
-FROM HourlyOrderTotals
-WHERE productId = 10;
-
-# A stream; will query the Orders stream.
-# Returns every hour in which at least one product #10 was sold.
-SELECT STREAM rowtime
-FROM HourlyOrderTotals
-WHERE productId = 10;
-```
-
-This approach is not limited to views and sub-queries.
-Following the approach set out in CQL [<a href="#ref1">1</a>], every query
-in streaming SQL is defined as a relational query and converted to a stream
-using the `STREAM` keyword in the top-most `SELECT`.
-
-If the `STREAM` keyword is present in sub-queries or view definitions, it has no
-effect.
-
-At query preparation time, Calcite figures out whether the relations referenced
-in the query can be converted to streams or historical relations.
-
-Sometimes a stream makes available some of its history (say the last 24 hours of
-data in an Apache Kafka [<a href="#ref2">2</a>] topic)
-but not all. At run time, Calcite figures out whether there is sufficient
-history to run the query, and if not, gives an error.
-
-## Hopping windows
-
-Previously we saw how to define a tumbling window using a `GROUP BY` clause.
-Each record contributed to a single sub-total record, the one containing its
-hour and product id.
-
-But suppose we want to emit, every hour, the number of each product ordered over
-the past three hours. To do this, we use `SELECT ... OVER` and a sliding window
-to combine multiple tumbling windows.
-
-```sql
-SELECT STREAM rowtime,
- productId,
- SUM(su) OVER w AS su,
- SUM(c) OVER w AS c
-FROM HourlyTotals
-WINDOW w AS (
- ORDER BY rowtime
- PARTITION BY productId
- RANGE INTERVAL '2' HOUR PRECEDING)
-```
-
-This query uses the `HourlyOrderTotals` view defined previously.
-The 2 hour interval combines the totals timestamped 09:00:00, 10:00:00 and
-11:00:00 for a particular product into a single total timestamped 11:00:00 and
-summarizing orders for that product between 09:00:00 and 12:00:00.
-
-## Limitations of tumbling and hopping windows
-
-In the present syntax, we acknowledge that it is not easy to create certain
-kinds of windows.
-
-First, let's consider tumbling windows over complex periods.
-
-The `FLOOR` and `CEIL` functions make is easy to create a tumbling window that
-emits on a whole time unit (say every hour, or every minute) but less easy to
-emit, say, every 15 minutes. One could imagine an extension to the `FLOOR`
-function that emits unique values on just about any periodic basis (say in 11
-minute intervals starting from midnight of the current day).
-
-Next, let's consider hopping windows whose retention period is not a multiple
-of its emission period. Say we want to output, at the top of each hour, the
-orders for the previous 7,007 seconds. If we were to simulate this hopping
-window using a sliding window over a tumbling window, as before, we would have
-to sum lots of 1-second windows (because 3,600 and 7,007 are co-prime).
-This is a lot of effort for both the system and the person writing the query.
-
-Calcite could perhaps solve this generalizing `GROUP BY` syntax, but we would
-be destroying the principle that an input row into a `GROUP BY` appears in
-precisely one output row.
-
-Calcite's SQL extensions for streaming queries are evolving. As we learn more
-about how people wish to query streams, we plan to make the language more
-expressive while remaining compatible with standard SQL and consistent with
-its principles, look and feel.
-
-## Sorting
-
-The story for `ORDER BY` is similar to `GROUP BY`.
-The syntax looks like regular SQL, but Calcite must be sure that it can deliver
-timely results. It therefore requires a monotonic expression on the leading edge
-of your `ORDER BY` key.
-
-```sql
-SELECT STREAM FLOOR(rowtime TO hour) AS rowtime, productId, orderId, units
-FROM Orders
-ORDER BY FLOOR(rowtime TO hour) ASC, units DESC;
-
- rowtime | productId | orderId | units
-----------+-----------+---------+-------
- 10:00:00 | 30 | 8 | 20
- 10:00:00 | 30 | 5 | 4
- 10:00:00 | 20 | 7 | 2
- 10:00:00 | 10 | 6 | 1
- 11:00:00 | 40 | 11 | 12
- 11:00:00 | 10 | 9 | 6
- 11:00:00 | 10 | 12 | 4
- 11:00:00 | 10 | 10 | 1
-```
-
-Most queries will return results in the order that they were inserted,
-because the engine is using streaming algorithms, but you should not rely on it.
-For example, consider this:
-
-```sql
-SELECT STREAM *
-FROM Orders
-WHERE productId = 10
-UNION ALL
-SELECT STREAM *
-FROM Orders
-WHERE productId = 30;
-
- rowtime | productId | orderId | units
-----------+-----------+---------+-------
- 10:17:05 | 10 | 6 | 1
- 10:17:00 | 30 | 5 | 4
- 10:18:07 | 30 | 8 | 20
- 11:02:00 | 10 | 9 | 6
- 11:04:00 | 10 | 10 | 1
- 11:24:11 | 10 | 12 | 4
-```
-
-The rows with `productId` = 30 are apparently out of order, probably because
-the `Orders` stream was partitioned on `productId` and the partitioned streams
-sent their data at different times.
-
-If you require a particular ordering, add an explicit `ORDER BY`:
-
-```sql
-SELECT STREAM *
-FROM Orders
-WHERE productId = 10
-UNION ALL
-SELECT STREAM *
-FROM Orders
-WHERE productId = 30
-ORDER BY rowtime;
-
- rowtime | productId | orderId | units
-----------+-----------+---------+-------
- 10:17:00 | 30 | 5 | 4
- 10:17:05 | 10 | 6 | 1
- 10:18:07 | 30 | 8 | 20
- 11:02:00 | 10 | 9 | 6
- 11:04:00 | 10 | 10 | 1
- 11:24:11 | 10 | 12 | 4
-```
-
-Calcite will probably implement the `UNION ALL` by merging using `rowtime`,
-which is only slightly less efficient.
-
-You only need to add an `ORDER BY` to the outermost query. If you need to,
-say, perform `GROUP BY` after a `UNION ALL`, Calcite will add an `ORDER BY`
-implicitly, in order to make the GROUP BY algorithm possible.
-
-## Table constructor
-
-The `VALUES` clause creates an inline table with a given set of rows.
-
-Streaming is disallowed. The set of rows never changes, and therefore a stream
-would never return any rows.
-
-```sql
-> SELECT STREAM * FROM (VALUES (1, 'abc'));
-
-ERROR: Cannot stream VALUES
-```
-
-## Sliding windows
-
-Standard SQL features so-called "analytic functions" that can be used in the
-`SELECT` clause. Unlike `GROUP BY`, these do not collapse records. For each
-record that goes in, one record comes out. But the aggregate function is based
-on a window of many rows.
-
-Let's look at an example.
-
-```sql
-SELECT STREAM rowtime,
- productId,
- units,
- SUM(units) OVER (ORDER BY rowtime RANGE INTERVAL '1' HOUR PRECEDING) unitsLastHour
-FROM Orders;
-```
-
-The feature packs a lot of power with little effort. You can have multiple
-functions in the `SELECT` clause, based on multiple window specifications.
-
-The following example returns orders whose average order size over the last
-10 minutes is greater than the average order size for the last week.
-
-```sql
-SELECT STREAM *
-FROM (
- SELECT STREAM rowtime,
- productId,
- units,
- AVG(units) OVER product (RANGE INTERVAL '10' MINUTE PRECEDING) AS m10,
- AVG(units) OVER product (RANGE INTERVAL '7' DAY PRECEDING) AS d7
- FROM Orders
- WINDOW product AS (
- ORDER BY rowtime
- PARTITION BY productId))
-WHERE m10 > d7;
-```
-
-For conciseness, here we use a syntax where you partially define a window
-using a `WINDOW` clause and then refine the window in each `OVER` clause.
-You could also define all windows in the `WINDOW` clause, or all windows inline,
-if you wish.
-
-But the real power goes beyond syntax. Behind the scenes, this query is
-maintaining two tables, and adding and removing values from sub-totals using
-with FIFO queues. But you can access those tables without introducing a join
-into the query.
-
-Some other features of the windowed aggregation syntax:
-* You can define windows based on row count.
-* The window can reference rows that have not yet arrived.
- (The stream will wait until they have arrived).
-* You can compute order-dependent functions such as `RANK` and median.
-
-## Cascading windows
-
-What if we want a query that returns a result for every record, like a
-sliding window, but resets totals on a fixed time period, like a
-tumbling window? Such a pattern is called a *cascading window*. Here
-is an example:
-
-```sql
-SELECT STREAM rowtime,
- productId,
- units,
- SUM(units) OVER (PARTITION BY FLOOR(rowtime TO HOUR)) AS unitsSinceTopOfHour
-FROM Orders;
-```
-
-It looks similar to a sliding window query, but the monotonic
-expression occurs within the `PARTITION BY` clause of the window. As
-the rowtime moves from from 10:59:59 to 11:00:00, `FLOOR(rowtime TO
-HOUR)` changes from 10:00:00 to 11:00:00, and therefore a new
-partition starts. The first row to arrive in the new hour will start a
-new total; the second row will have a total that consists of two rows,
-and so on.
-
-Calcite knows that the old partition will never be used again, so
-removes all sub-totals for that partition from its internal storage.
-
-Analytic functions that using cascading and sliding windows can be
-combined in the same query.
-
-## State of the stream
-
-Not all concepts in this article have been implemented in Calcite.
-And others may be implemented in Calcite but not in a particular adapter
-such as Samza SQL [<a href="#ref3">3</a>].
-
-### Implemented
-* Streaming SELECT, WHERE, GROUP BY, HAVING, UNION ALL, ORDER BY
-* FLOOR and CEILING functions
-* Monotonicity
-* Streaming VALUES is disallowed
-
-### Not implemented
-* Stream-to-stream JOIN
-* Stream-to-table JOIN
-* Stream on view
-* Streaming UNION ALL with ORDER BY (merge)
-* Relational query on stream
-* Streaming windowed aggregation (sliding and cascading windows)
-* Check that STREAM in sub-queries and views is ignored
-* Check that streaming ORDER BY cannot have OFFSET or LIMIT
-* Limited history; at run time, check that there is sufficient history
- to run the query.
-
-### To do in this document

-# CSV Adapter Tutorial
-
-Calcite-example-CSV is a fully functional adapter for
-<a href="https://github.com/apache/incubator-calcite">Calcite</a> that reads
-text files in
-<a href="http://en.wikipedia.org/wiki/Comma-separated_values">CSV
-(comma-separated values)</a> format. It is remarkable that a couple of
-hundred lines of Java code are sufficient to provide full SQL query
-capability.
-
-CSV also serves as a template for building adapters to other
-data formats. Even though there are not many lines of code, it covers
-several important concepts:
-* user-defined schema using SchemaFactory and Schema interfaces;
-* declaring schemas in a model JSON file;
-* declaring views in a model JSON file;
-* user-defined table using the Table interface;
-* determining the record type of a table;
-* a simple implementation of Table, using the ScannableTable interface, that
- enumerates all rows directly;
-* a more advanced implementation that implements FilterableTable, and can
- filter out rows according to simple predicates;
-* advanced implementation of Table, using TranslatableTable, that translates
- to relational operators using planner rules.
-
-## Download and build
-
-You need Java (1.7 or higher; 1.8 preferred), git and maven (3.2.1 or later).
-
-```bash
-$ git clone https://github.com/apache/incubator-calcite.git
-$ cd incubator-calcite
-$ mvn install -DskipTests -Dcheckstyle.skip=true
-$ cd example/csv
-```
-
-## First queries
-
-Now let's connect to Calcite using
-<a href="https://github.com/julianhyde/sqlline">sqlline</a>, a SQL shell
-that is included in this project.
-
-```bash
-$ ./sqlline
-sqlline> !connect jdbc:calcite:model=target/test-classes/model.json admin admin
-```
-
-(If you are running Windows, the command is `sqlline.bat`.)
-
-Execute a metadata query:
-
-```bash
-sqlline> !tables
-+------------+--------------+-------------+---------------+----------+------+
-| TABLE_CAT | TABLE_SCHEM | TABLE_NAME | TABLE_TYPE | REMARKS | TYPE |
-+------------+--------------+-------------+---------------+----------+------+
-| null | SALES | DEPTS | TABLE | null | null |
-| null | SALES | EMPS | TABLE | null | null |
-| null | SALES | HOBBIES | TABLE | null | null |
-| null | metadata | COLUMNS | SYSTEM_TABLE | null | null |
-| null | metadata | TABLES | SYSTEM_TABLE | null | null |
-+------------+--------------+-------------+---------------+----------+------+
-```
-
-(JDBC experts, note: sqlline's <code>!tables</code> command is just executing
-<a href="http://docs.oracle.com/javase/7/docs/api/java/sql/DatabaseMetaData.html#getTables(java.lang.String, java.lang.String, java.lang.String, java.lang.String[])"><code>DatabaseMetaData.getTables()</code></a>
-behind the scenes.
-It has other commands to query JDBC metadata, such as <code>!columns</code> and <code>!describe</code>.)
-
-As you can see there are 5 tables in the system: tables
-<code>EMPS</code>, <code>DEPTS</code> and <code>HOBBIES</code> in the current
-<code>SALES</code> schema, and <code>COLUMNS</code> and
-<code>TABLES</code> in the system <code>metadata</code> schema. The
-system tables are always present in Calcite, but the other tables are
-provided by the specific implementation of the schema; in this case,
-the <code>EMPS</code> and <code>DEPTS</code> tables are based on the
-<code>EMPS.csv</code> and <code>DEPTS.csv</code> files in the
-<code>target/test-classes</code> directory.
-
-Let's execute some queries on those tables, to show that Calcite is providing
-a full implementation of SQL. First, a table scan:
-
-```bash
-sqlline> SELECT * FROM emps;
-+--------+--------+---------+---------+----------------+--------+-------+---+
-| EMPNO | NAME | DEPTNO | GENDER | CITY | EMPID | AGE | S |
-+--------+--------+---------+---------+----------------+--------+-------+---+
-| 100 | Fred | 10 | | | 30 | 25 | t |
-| 110 | Eric | 20 | M | San Francisco | 3 | 80 | n |
-| 110 | John | 40 | M | Vancouver | 2 | null | f |
-| 120 | Wilma | 20 | F | | 1 | 5 | n |
-| 130 | Alice | 40 | F | Vancouver | 2 | null | f |
-+--------+--------+---------+---------+----------------+--------+-------+---+
-```
-
-Now JOIN and GROUP BY:
-
-```bash
-sqlline> SELECT d.name, COUNT(*)
-. . . .> FROM emps AS e JOIN depts AS d ON e.deptno = d.deptno
-. . . .> GROUP BY d.name;
-+------------+---------+
-| NAME | EXPR$1 |
-+------------+---------+
-| Sales | 1 |
-| Marketing | 2 |
-+------------+---------+
-```
-
-Last, the VALUES operator generates a single row, and is a convenient
-way to test expressions and SQL built-in functions:
-
-```bash
-sqlline> VALUES CHAR_LENGTH('Hello, ' || 'world!');
-+---------+
-| EXPR$0 |
-+---------+
-| 13 |
-+---------+
-```
-
-Calcite has many other SQL features. We don't have time to cover them
-here. Write some more queries to experiment.
-
-## Schema discovery
-
-Now, how did Calcite find these tables? Remember, core Calcite does not
-know anything about CSV files. (As a "database without a storage
-layer", Calcite doesn't know about any file formats.) Calcite knows about
-those tables because we told it to run code in the calcite-example-csv
-project.
-
-There are a couple of steps in that chain. First, we define a schema
-based on a schema factory class in a model file. Then the schema
-factory creates a schema, and the schema creates several tables, each
-of which knows how to get data by scanning a CSV file. Last, after
-Calcite has parsed the query and planned it to use those tables, Calcite
-invokes the tables to read the data as the query is being
-executed. Now let's look at those steps in more detail.
-
-On the JDBC connect string we gave the path of a model in JSON
-format. Here is the model:
-
-```json
-{
- version: '1.0',
- defaultSchema: 'SALES',
- schemas: [
- {
- name: 'SALES',
- type: 'custom',
- factory: 'org.apache.calcite.adapter.csv.CsvSchemaFactory',
- operand: {
- directory: 'target/test-classes/sales'
- }
- }
- ]
-}
-```
-
-The model defines a single schema called 'SALES'. The schema is
-powered by a plugin class,
-<a href="../example/csv/src/main/java/org/apache/calcite/adapter/csv/CsvSchemaFactory.java">org.apache.calcite.adapter.csv.CsvSchemaFactory</a>,
-which is part of the
-calcite-example-csv project and implements the Calcite interface
-<a href="http://www.hydromatic.net/calcite/apidocs/org/apache/calcite/schema/SchemaFactory.html">SchemaFactory</a>.
-Its <code>create</code> method instantiates a
-schema, passing in the <code>directory</code> argument from the model file:
-
-```java
-public Schema create(SchemaPlus parentSchema, String name,
- Map<String, Object> operand) {
- String directory = (String) operand.get("directory");
- String flavorName = (String) operand.get("flavor");
- CsvTable.Flavor flavor;
- if (flavorName == null) {
- flavor = CsvTable.Flavor.SCANNABLE;
- } else {
- flavor = CsvTable.Flavor.valueOf(flavorName.toUpperCase());
- }
- return new CsvSchema(
- new File(directory),
- flavor);
-}
-```
-
-Driven by the model, the schema factory instantiates a single schema
-called 'SALES'. The schema is an instance of
-<a href="../example/csv/src/main/java/org/apache/calcite/adapter/csv/CsvSchema.java">org.apache.calcite.adapter.csv.CsvSchema</a>
-and implements the Calcite interface <a
-href="http://www.hydromatic.net/calcite/apidocs/org/apache/calcite/schema/Schema.html">Schema</a>.
-
-A schema's job is to produce a list of tables. (It can also list sub-schemas and
-table-functions, but these are advanced features and calcite-example-csv does
-not support them.) The tables implement Calcite's
-<a href="http://www.hydromatic.net/calcite/apidocs/org/apache/calcite/schema/Table.html">Table</a>
-interface. <code>CsvSchema</code> produces tables that are instances of
-<a href="../example/csv/src/main/java/org/apache/calcite/adapter/csv/CsvTable.java">CsvTable</a>
-and its sub-classes.
-
-Here is the relevant code from <code>CsvSchema</code>, overriding the
-<code><a href="http://www.hydromatic.net/calcite/apidocs/org/apache/calcite/schema/impl/AbstractSchema.html#getTableMap()">getTableMap()</a></code>
-method in the <code>AbstractSchema</code> base class.
-
-```java
-protected Map<String, Table> getTableMap() {
- // Look for files in the directory ending in ".csv", ".csv.gz", ".json",
- // ".json.gz".
- File[] files = directoryFile.listFiles(
- new FilenameFilter() {
- public boolean accept(File dir, String name) {
- final String nameSansGz = trim(name, ".gz");
- return nameSansGz.endsWith(".csv")
- || nameSansGz.endsWith(".json");
- }
- });
- if (files == null) {
- System.out.println("directory " + directoryFile + " not found");
- files = new File[0];
- }
- // Build a map from table name to table; each file becomes a table.
- final ImmutableMap.Builder<String, Table> builder = ImmutableMap.builder();
- for (File file : files) {
- String tableName = trim(file.getName(), ".gz");
- final String tableNameSansJson = trimOrNull(tableName, ".json");
- if (tableNameSansJson != null) {
- JsonTable table = new JsonTable(file);
- builder.put(tableNameSansJson, table);
- continue;
- }
- tableName = trim(tableName, ".csv");
- final Table table = createTable(file);
- builder.put(tableName, table);
- }
- return builder.build();
-}
-
-/** Creates different sub-type of table based on the "flavor" attribute. */
-private Table createTable(File file) {
- switch (flavor) {
- case TRANSLATABLE:
- return new CsvTranslatableTable(file, null);
- case SCANNABLE:
- return new CsvScannableTable(file, null);
- case FILTERABLE:
- return new CsvFilterableTable(file, null);
- default:
- throw new AssertionError("Unknown flavor " + flavor);
- }
-}
-```
-
-The schema scans the directory and finds all files whose name ends
-with ".csv" and creates tables for them. In this case, the directory
-is <code>target/test-classes/sales</code> and contains files
-<code>EMPS.csv</code> and <code>DEPTS.csv</code>, which these become
-the tables <code>EMPS</code> and <code>DEPTS</code>.
-
-## Tables and views in schemas
-
-Note how we did not need to define any tables in the model; the schema
-generated the tables automatically.
-
-You can define extra tables,
-beyond those that are created automatically,
-using the <code>tables</code> property of a schema.
-
-Let's see how to create
-an important and useful type of table, namely a view.
-
-A view looks like a table when you are writing a query, but it doesn't store data.
-It derives its result by executing a query.
-The view is expanded while the query is being planned, so the query planner
-can often perform optimizations like removing expressions from the SELECT
-clause that are not used in the final result.
-
-Here is a schema that defines a view:
-
-```json
-{
- version: '1.0',
- defaultSchema: 'SALES',
- schemas: [
- {
- name: 'SALES',
- type: 'custom',
- factory: 'org.apache.calcite.adapter.csv.CsvSchemaFactory',
- operand: {
- directory: 'target/test-classes/sales'
- },
- tables: [
- {
- name: 'FEMALE_EMPS',
- type: 'view',
- sql: 'SELECT * FROM emps WHERE gender = \'F\''
- }
- ]
- }
- ]
-}
-```
-
-The line <code>type: 'view'</code> tags <code>FEMALE_EMPS</code> as a view,
-as opposed to a regular table or a custom table.
-Note that single-quotes within the view definition are escaped using a
-back-slash, in the normal way for JSON.
-
-JSON doesn't make it easy to author long strings, so Calcite supports an
-alternative syntax. If your view has a long SQL statement, you can instead
-supply a list of lines rather than a single string:
-
-```json
- {
- name: 'FEMALE_EMPS',
- type: 'view',
- sql: [
- 'SELECT * FROM emps',
- 'WHERE gender = \'F\''
- ]
- }
-```
-
-Now we have defined a view, we can use it in queries just as if it were a table:
-
-```sql
-sqlline> SELECT e.name, d.name FROM female_emps AS e JOIN depts AS d on e.deptno = d.deptno;
-+--------+------------+
-| NAME | NAME |
-+--------+------------+
-| Wilma | Marketing |
-+--------+------------+
-```
-
-## Custom tables
-
-Custom tables are tables whose implementation is driven by user-defined code.
-They don't need to live in a custom schema.
-
-There is an example in <code>model-with-custom-table.json</code>:
-
-```json
-{
- version: '1.0',
- defaultSchema: 'CUSTOM_TABLE',
- schemas: [
- {
- name: 'CUSTOM_TABLE',
- tables: [
- {
- name: 'EMPS',
- type: 'custom',
- factory: 'org.apache.calcite.adapter.csv.CsvTableFactory',
- operand: {
- file: 'target/test-classes/sales/EMPS.csv.gz',
- flavor: "scannable"
- }
- }
- ]
- }
- ]
-}
-```
-
-We can query the table in the usual way:
-
-```sql
-sqlline> !connect jdbc:calcite:model=target/test-classes/model-with-custom-table.json admin admin
-sqlline> SELECT empno, name FROM custom_table.emps;
-+--------+--------+
-| EMPNO | NAME |
-+--------+--------+
-| 100 | Fred |
-| 110 | Eric |
-| 110 | John |
-| 120 | Wilma |
-| 130 | Alice |
-+--------+--------+
-```
-
-The schema is a regular one, and contains a custom table powered by
-<a href="../example/csv/src/main/java/org/apache/calcite/adapter/csv/CsvTableFactory.java">org.apache.calcite.adapter.csv.CsvTableFactory</a>,
-which implements the Calcite interface
-<a href="http://www.hydromatic.net/calcite/apidocs/org/apache/calcite/schema/TableFactory.html">TableFactory</a>.
-Its <code>create</code> method instantiates a <code>CsvScannableTable</code>,
-passing in the <code>file</code> argument from the model file:
-
-```java
-public CsvTable create(SchemaPlus schema, String name,
- Map<String, Object> map, RelDataType rowType) {
- String fileName = (String) map.get("file");
- final File file = new File(fileName);
- final RelProtoDataType protoRowType =
- rowType != null ? RelDataTypeImpl.proto(rowType) : null;
- return new CsvScannableTable(file, protoRowType);
-}
-```
-
-Implementing a custom table is often a simpler alternative to implementing
-a custom schema. Both approaches might end up creating a similar implementation
-of the <code>Table</code> interface, but for the custom table you don't
-need to implement metadata discovery. (<code>CsvTableFactory</code>
-creates a <code>CsvScannableTable</code>, just as <code>CsvSchema</code> does,
-but the table implementation does not scan the filesystem for .csv files.)
-
-Custom tables require more work for the author of the model (the author
-needs to specify each table and its file explicitly) but also give the author
-more control (say, providing different parameters for each table).
-
-## Comments in models
-
-Models can include comments using `/* ... */` and `//` syntax:
-
-```json
-{
- version: '1.0',
- /* Multi-line
- comment. */
- defaultSchema: 'CUSTOM_TABLE',
- // Single-line comment.
- schemas: [
- ..
- ]
-}
-```
-
-(Comments are not standard JSON, but are a harmless extension.)
-
-## Optimizing queries using planner rules
-
-The table implementations we have seen so far are fine as long as the tables
-don't contain a great deal of data. But if your customer table has, say, a
-hundred columns and a million rows, you would rather that the system did not
-retrieve all of the data for every query. You would like Calcite to negotiate
-with the adapter and find a more efficient way of accessing the data.
-
-This negotiation is a simple form of query optimization. Calcite supports query
-optimization by adding <i>planner rules</i>. Planner rules operate by
-looking for patterns in the query parse tree (for instance a project on top
-of a certain kind of table), and
-
-Planner rules are also extensible, like schemas and tables. So, if you have a
-data store that you want to access via SQL, you first define a custom table or
-schema, and then you define some rules to make the access efficient.
-
-To see this in action, let's use a planner rule to access
-a subset of columns from a CSV file. Let's run the same query against two very
-similar schemas:
-
-```sql
-sqlline> !connect jdbc:calcite:model=target/test-classes/model.json admin admin
-sqlline> explain plan for select name from emps;
-+-----------------------------------------------------+
-| PLAN |
-+-----------------------------------------------------+
-| EnumerableCalcRel(expr#0..9=[{inputs}], NAME=[$t1]) |
-| EnumerableTableAccessRel(table=[[SALES, EMPS]]) |
-+-----------------------------------------------------+
-sqlline> !connect jdbc:calcite:model=target/test-classes/smart.json admin admin
-sqlline> explain plan for select name from emps;
-+-----------------------------------------------------+
-| PLAN |
-+-----------------------------------------------------+
-| EnumerableCalcRel(expr#0..9=[{inputs}], NAME=[$t1]) |
-| CsvTableScan(table=[[SALES, EMPS]]) |
-+-----------------------------------------------------+
-```
-
-What causes the difference in plan? Let's follow the trail of evidence. In the
-<code>smart.json</code> model file, there is just one extra line:
-
-```json
-flavor: "translatable"
-```
-
-This causes a <code>CsvSchema</code> to be created with
-<code>flavor = TRANSLATABLE</code>,
-and its <code>createTable</code> method creates instances of
-<a href="../example/csv/src/main/java/org/apache/calcite/adapter/csv/CsvTranslatableTable.java">CsvTranslatableTable</a>
-rather than a <code>CsvScannableTable</code>.
-
-<code>CsvTranslatableTable</code> implements the
-<code><a href="http://www.hydromatic.net/calcite/apidocs/org/apache/calcite/schema/TranslatableTable.html#toRel()">TranslatableTable.toRel()</a></code>
-method to create
-<a href="../example/csv/src/main/java/org/apache/calcite/adapter/csv/CsvTableScan.java">CsvTableScan</a>.
-Table scans are the leaves of a query operator tree.
-The usual implementation is
-<code><a href="http://www.hydromatic.net/calcite/apidocs/org/apache/calcite/adapter/enumerable/EnumerableTableScan.html">EnumerableTableScan</a></code>,
-but we have created a distinctive sub-type that will cause rules to fire.
-
-Here is the rule in its entirety:
-
-```java
-public class CsvProjectTableScanRule extends RelOptRule {
- public static final CsvProjectTableScanRule INSTANCE =
- new CsvProjectTableScanRule();
-
- private CsvProjectTableScanRule() {
- super(
- operand(Project.class,
- operand(CsvTableScan.class, none())),
- "CsvProjectTableScanRule");
- }
-
- @Override
- public void onMatch(RelOptRuleCall call) {
- final Project project = call.rel(0);
- final CsvTableScan scan = call.rel(1);
- int[] fields = getProjectFields(project.getProjects());
- if (fields == null) {
- // Project contains expressions more complex than just field references.
- return;
- }
- call.transformTo(
- new CsvTableScan(
- scan.getCluster(),
- scan.getTable(),
- scan.csvTable,
- fields));
- }
-
- private int[] getProjectFields(List<RexNode> exps) {
- final int[] fields = new int[exps.size()];
- for (int i = 0; i < exps.size(); i++) {
- final RexNode exp = exps.get(i);
- if (exp instanceof RexInputRef) {
- fields[i] = ((RexInputRef) exp).getIndex();
- } else {
- return null; // not a simple projection
- }
- }
- return fields;
- }
-}
-```
-
-The constructor declares the pattern of relational expressions that will cause
-the rule to fire.
-
-The <code>onMatch</code> method generates a new relational expression and calls
-<code><a href="http://www.hydromatic.net/calcite/apidocs/org/apache/calcite/plan/RelOptRuleCall.html#transformTo(org.apache.calcite.rel.RelNode)">RelOptRuleCall.transformTo()</a></code>
-to indicate that the rule has fired successfully.
-
-## The query optimization process
-
-There's a lot to say about how clever Calcite's query planner is, but we won't
-say it here. The cleverness is designed to take the burden off you, the writer
-of planner rules.
-
-First, Calcite doesn't fire rules in a prescribed order. The query optimization
-process follows many branches of a branching tree, just like a chess playing
-program examines many possible sequences of moves. If rules A and B both match a
-given section of the query operator tree, then Calcite can fire both.
-
-Second, Calcite uses cost in choosing between plans, but the cost model doesn't
-prevent rules from firing which may seem to be more expensive in the short term.
-
-Many optimizers have a linear optimization scheme. Faced with a choice between
-rule A and rule B, as above, such an optimizer needs to choose immediately. It
-might have a policy such as "apply rule A to the whole tree, then apply rule B
-to the whole tree", or apply a cost-based policy, applying the rule that
-produces the cheaper result.
-
-Calcite doesn't require such compromises.
-This makes it simple to combine various sets of rules.
-If, say you want to combine rules to recognize materialized views with rules to
-read from CSV and JDBC source systems, you just give Calcite the set of all
-rules and tell it to go at it.
-
-Calcite does use a cost model. The cost model decides which plan to ultimately
-use, and sometimes to prune the search tree to prevent the search space from
-exploding, but it never forces you to choose between rule A and rule B. This is
-important, because it avoids falling into local minima in the search space that
-are not actually optimal.
-
-Also (you guessed it) the cost model is pluggable, as are the table and query
-operator statistics it is based upon. But that can be a subject for later.
-
-## JDBC adapter
-
-The JDBC adapter maps a schema in a JDBC data source as a Calcite schema.
-
-For example, this schema reads from a MySQL "foodmart" database:
-
-```json
-{
- version: '1.0',
- defaultSchema: 'FOODMART',
- schemas: [
- {
- name: 'FOODMART',
- type: 'custom',
- factory: 'org.apache.calcite.adapter.jdbc.JdbcSchema$Factory',
- operand: {
- jdbcDriver: 'com.mysql.jdbc.Driver',
- jdbcUrl: 'jdbc:mysql://localhost/foodmart',
- jdbcUser: 'foodmart',
- jdbcPassword: 'foodmart'
- }
- }
- ]
-}
-```
-
-(The FoodMart database will be familiar to those of you who have used
-the Mondrian OLAP engine, because it is Mondrian's main test data
-set. To load the data set, follow <a
-href="http://mondrian.pentaho.com/documentation/installation.php#2_Set_up_test_data">Mondrian's
-installation instructions</a>.)
-
-<b>Current limitations</b>: The JDBC adapter currently only pushes
-down table scan operations; all other processing (filtering, joins,
-aggregations and so forth) occurs within Calcite. Our goal is to push
-down as much processing as possible to the source system, translating
-syntax, data types and built-in functions as we go. If a Calcite query
-is based on tables from a single JDBC database, in principle the whole
-query should go to that database. If tables are from multiple JDBC
-sources, or a mixture of JDBC and non-JDBC, Calcite will use the most
-efficient distributed query approach that it can.
-
-## The cloning JDBC adapter
-
-The cloning JDBC adapter creates a hybrid database. The data is
-sourced from a JDBC database but is read into in-memory tables the
-first time each table is accessed. Calcite evaluates queries based on
-those in-memory tables, effectively a cache of the database.
-
-For example, the following model reads tables from a MySQL
-"foodmart" database:
-
-```json
-{
- version: '1.0',
- defaultSchema: 'FOODMART_CLONE',
- schemas: [
- {
- name: 'FOODMART_CLONE',
- type: 'custom',
- factory: 'org.apache.calcite.adapter.clone.CloneSchema$Factory',
- operand: {
- jdbcDriver: 'com.mysql.jdbc.Driver',
- jdbcUrl: 'jdbc:mysql://localhost/foodmart',
- jdbcUser: 'foodmart',
- jdbcPassword: 'foodmart'
- }
- }
- ]
-}
-```
-
-Another technique is to build a clone schema on top of an existing
-schema. You use the <code>source</code> property to reference a schema
-defined earlier in the model, like this:
-
-```json
-{
- version: '1.0',
- defaultSchema: 'FOODMART_CLONE',
- schemas: [
- {
- name: 'FOODMART',
- type: 'custom',
- factory: 'org.apache.calcite.adapter.jdbc.JdbcSchema$Factory',
- operand: {
- jdbcDriver: 'com.mysql.jdbc.Driver',
- jdbcUrl: 'jdbc:mysql://localhost/foodmart',
- jdbcUser: 'foodmart',
- jdbcPassword: 'foodmart'
- }
- },
- {
- name: 'FOODMART_CLONE',
- type: 'custom',
- factory: 'org.apache.calcite.adapter.clone.CloneSchema$Factory',
- operand: {
- source: 'FOODMART'
- }
- }
- ]
-}
-```
-
-You can use this approach to create a clone schema on any type of
-schema, not just JDBC.
-
-The cloning adapter isn't the be-all and end-all. We plan to develop
-more sophisticated caching strategies, and a more complete and
-efficient implementation of in-memory tables, but for now the cloning
-JDBC adapter shows what is possible and allows us to try out our
-initial implementations.

+
+Relational algebra is at the heart of Calcite. Every query is
+represented as a tree of relational operators. You can translate from
+SQL to relational algebra, or you can build the tree directly.
+
+Planner rules transform expression trees using mathematical identities
+that preserve semantics. For example, it is valid to push a filter
+into an input of an inner join if the filter does not reference
+columns from the other input.
+
+Calcite optimizes queries by repeatedly applying planner rules to a
+relational expression. A cost model guides the process, and the
+planner engine generates an alternative expression that has the same
+semantics as the original but a lower cost.
+
+The planning process is extensible. You can add your own relational
+operators, planner rules, cost model, and statistics.

+
+Avatica's Java binding has very few dependencies.
+Even though it is part of Apache Calcite it does not depend on other parts of
+Calcite. It depends only on JDK 1.7+ and Jackson.
+
+Avatica's wire protocol is JSON over HTTP.
+The Java implementation uses Jackson to convert request/response command
+objects to/from JSON.
+
+Avatica-Server is a Java implementation of Avatica RPC.
+It embeds the Jetty HTTP server.
+
+Core concepts:
+
+* Meta is a local API sufficient to implement any Avatica provider
+* Factory creates implementations of the JDBC classes (Driver, Connection,
+ Statement, ResultSet) on top of a Meta
+* Service is an interface that implements the functions of Meta in terms
+ of request and response command objects
+
+## JDBC
+
+Avatica implements JDBC by means of Factory.
+Factory creates implementations of the JDBC classes (Driver, Connection,
+Statement, PreparedStatement, ResultSet) on top of a Meta.
+
+## ODBC
+
+Work has not started on Avatica ODBC.
+
+Avatica ODBC would use the same wire protocol and could use the same server
+implementation in Java. The ODBC client would be written in C or C++.
+
+Since the Avatica protocol abstracts many of the differences between providers,
+the same ODBC client could be used for different databases.
+
+## Project structure
+
+We know that it is important that client libraries have minimal dependencies.
+
+Avatica is currently part of Apache Calcite.
+It does not depend upon any other part of Calcite.
+At some point Avatica could become a separate project.
+
+Packages:
+
+* [org.apache.calcite.avatica](/apidocs/org/apache/calcite/avatica/package-summary.html) Core framework
+* [org.apache.calcite.avatica.remote](/apidocs/org/apache/calcite/avatica/remote/package-summary.html) JDBC driver that uses remote procedure calls

+
+Calcite has extended SQL and relational algebra in order to support
+streaming queries.
+
+Streams are collections to records that flow continuously, and forever.
+Unlike tables, they are not typically stored on disk, but flow over the
+network and are held for short periods of time in memory.
+
+Streams complement tables because they represent what is happening in the
+present and future of the enterprise whereas tables represent the past.
+It is very common for a stream to be archived into a table.
+
+Like tables, you often want to query streams in a high-level language
+based on relational algebra, validated according to a schema, and optimized
+to take advantage of available resources and algorithms.
+
+Calcite's SQL is an extension to standard SQL, not another 'SQL-like' language.
+The distinction is important, for several reasons:
+
+* Streaming SQL is easy to learn for anyone who knows regular SQL.
+* The semantics are clear, because we aim to produce the same results on a
+ stream as if the same data were in a table.
+* You can write queries that combine streams and tables (or the history of
+ a stream, which is basically an in-memory table).
+* Lots of existing tools can generate standard SQL.
+
+If you don't use the `STREAM` keyword, you are back in regular
+standard SQL.
+
+## An example schema
+
+Our streaming SQL examples use the following schema:
+
+* `Orders (rowtime, productId, orderId, units)` - a stream and a table
+* `Products (rowtime, productId, name)` - a table
+* `Shipments (rowtime, orderId)` - a stream
+
+## A simple query
+
+Let's start with the simplest streaming query:
+
+{% highlight sql %}
+SELECT STREAM *
+FROM Orders;
+
+ rowtime | productId | orderId | units
+----------+-----------+---------+-------
+ 10:17:00 | 30 | 5 | 4
+ 10:17:05 | 10 | 6 | 1
+ 10:18:05 | 20 | 7 | 2
+ 10:18:07 | 30 | 8 | 20
+ 11:02:00 | 10 | 9 | 6
+ 11:04:00 | 10 | 10 | 1
+ 11:09:30 | 40 | 11 | 12
+ 11:24:11 | 10 | 12 | 4
+{% endhighlight %}
+
+This query reads all columns and rows from the `Orders` stream.
+Like any streaming query, it never terminates. It outputs a record whenever
+a record arrives in `Orders`.
+
+Type `Control-C` to terminate the query.
+
+The `STREAM` keyword is the main extension in streaming SQL. It tells the
+system that you are interested in incoming orders, not existing ones. The query
+
+{% highlight sql %}
+SELECT *
+FROM Orders;
+
+ rowtime | productId | orderId | units
+----------+-----------+---------+-------
+ 08:30:00 | 10 | 1 | 3
+ 08:45:10 | 20 | 2 | 1
+ 09:12:21 | 10 | 3 | 10
+ 09:27:44 | 30 | 4 | 2
+
+4 records returned.
+{% endhighlight %}
+
+is also valid, but will print out all existing orders and then terminate. We
+call it a *relational* query, as opposed to *streaming*. It has traditional
+SQL semantics.
+
+`Orders` is special, in that it has both a stream and a table. If you try to run
+a streaming query on a table, or a relational query on a stream, Calcite gives
+an error:
+
+{% highlight sql %}
+> SELECT * FROM Shipments;
+ERROR: Cannot convert stream 'SHIPMENTS' to a table
+
+> SELECT STREAM * FROM Products;
+ERROR: Cannot convert table 'PRODUCTS' to a stream
+{% endhighlight %}
+
+# Filtering rows
+
+Just as in regular SQL, you use a `WHERE` clause to filter rows:
+
+{% highlight sql %}
+SELECT STREAM *
+FROM Orders
+WHERE units > 3;
+
+ rowtime | productId | orderId | units
+----------+-----------+---------+-------
+ 10:17:00 | 30 | 5 | 4
+ 10:18:07 | 30 | 8 | 20
+ 11:02:00 | 10 | 9 | 6
+ 11:09:30 | 40 | 11 | 12
+ 11:24:11 | 10 | 12 | 4
+{% endhighlight %}
+
+# Projecting expressions
+
+Use expressions in the `SELECT` clause to choose which columns to return or
+compute expressions:
+
+{% highlight sql %}
+SELECT STREAM rowtime,
+ 'An order for ' || units || ' '
+ || CASE units WHEN 1 THEN 'unit' ELSE 'units' END
+ || ' of product #' || productId AS description
+FROM Orders;
+
+ rowtime | description
+----------+---------------------------------------
+ 10:17:00 | An order for 4 units of product #30
+ 10:17:05 | An order for 1 unit of product #10
+ 10:18:05 | An order for 2 units of product #20
+ 10:18:07 | An order for 20 units of product #30
+ 11:02:00 | An order by 6 units of product #10
+ 11:04:00 | An order by 1 unit of product #10
+ 11:09:30 | An order for 12 units of product #40
+ 11:24:11 | An order by 4 units of product #10
+{% endhighlight %}
+
+We recommend that you always include the `rowtime` column in the `SELECT`
+clause. Having a sorted timestamp in each stream and streaming query makes it
+possible to do advanced calculations later, such as `GROUP BY` and `JOIN`.
+
+# Tumbling windows
+
+There are several ways to compute aggregate functions on streams. The
+differences are:
+
+* How many rows come out for each row in?
+* Does each incoming value appear in one total, or more?
+* What defines the "window", the set of rows that contribute to a given output row?
+* Is the result a stream or a relation?
+
+First we'll look a *tumbling window*, which is defined by a streaming
+`GROUP BY`. Here is an example:
+
+{% highlight sql %}
+SELECT STREAM FLOOR(rowtime TO HOUR) AS rowtime,
+ productId,
+ COUNT(*) AS c,
+ SUM(units) AS units
+FROM Orders
+GROUP BY FLOOR(rowtime TO HOUR), productId;
+
+ rowtime | productId | c | units
+----------+-----------+---------+-------
+ 10:00:00 | 30 | 2 | 24
+ 10:00:00 | 10 | 1 | 1
+ 10:00:00 | 20 | 1 | 7
+ 11:00:00 | 10 | 3 | 11
+ 11:00:00 | 40 | 1 | 12
+{% endhighlight %}
+
+The result is a stream. At 11 o'clock, Calcite emits a sub-total for every
+`productId` that had an order since 10 o'clock. At 12 o'clock, it will emit
+the orders that occurred between 11:00 and 12:00. Each input row contributes to
+only one output row.
+
+How did Calcite know that the 10:00:00 sub-totals were complete at 11:00:00,
+so that it could emit them? It knows that `rowtime` is increasing, and it knows
+that `FLOOR(rowtime TO HOUR)` is also increasing. So, once it has seen a row
+at or after 11:00:00, it will never see a row that will contribute to a 10:00:00
+total.
+
+A column or expression that is increasing or decreasing is said to be
+*monotonic*. Without a monotonic expression in the `GROUP BY` clause, Calcite is
+not able to make progress, and it will not allow the query:
+
+{% highlight sql %}
+> SELECT STREAM productId,
+> COUNT(*) AS c,
+> SUM(units) AS units
+> FROM Orders
+> GROUP BY productId;
+ERROR: Streaming aggregation requires at least one monotonic expression in GROUP BY clause
+{% endhighlight %}
+
+Monotonic columns need to be declared in the schema. The monotonicity is
+enforced when records enter the stream and assumed by queries that read from
+that stream. We recommend that you give each stream a timestamp column called
+`rowtime`, but you can declare others, `orderId`, for example.
+
+# Filtering after aggregation
+
+As in standard SQL, you can apply a `HAVING` clause to filter rows emitted by
+a streaming `GROUP BY`:
+
+{% highlight sql %}
+SELECT STREAM FLOOR(rowtime TO HOUR) AS rowtime,
+ productId
+FROM Orders
+GROUP BY FLOOR(rowtime TO HOUR), productId
+HAVING COUNT(*) > 2 OR SUM(units) > 10;
+
+ rowtime | productId
+----------+-----------
+ 10:00:00 | 30
+ 11:00:00 | 10
+ 11:00:00 | 40
+{% endhighlight %}
+
+# Sub-queries, views and SQL's closure property
+
+The previous `HAVING` query can be expressed using a `WHERE` clause on a
+sub-query:
+
+{% highlight sql %}
+SELECT STREAM rowtime, productId
+FROM (
+ SELECT FLOOR(rowtime TO HOUR) AS rowtime,
+ productId,
+ COUNT(*) AS c,
+ SUM(units) AS su
+ FROM Orders
+ GROUP BY FLOOR(rowtime TO HOUR), productId)
+WHERE c > 2 OR su > 10;
+
+ rowtime | productId
+----------+-----------
+ 10:00:00 | 30
+ 11:00:00 | 10
+ 11:00:00 | 40
+{% endhighlight %}
+
+`HAVING` was introduced in the early days of SQL, when a way was needed to
+perform a filter *after* aggregation. (Recall that `WHERE` filters rows before
+they enter the `GROUP BY` clause.)
+
+Since then, SQL has become a mathematically closed language, which means that
+any operation you can perform on a table can also perform on a query.
+
+The *closure property* of SQL is extremely powerful. Not only does it render
+`HAVING` obsolete (or, at least, reduce it to syntactic sugar), it makes views
+possible:
+
+{% highlight sql %}
+CREATE VIEW HourlyOrderTotals (rowtime, productId, c, su) AS
+ SELECT FLOOR(rowtime TO HOUR),
+ productId,
+ COUNT(*),
+ SUM(units)
+ FROM Orders
+ GROUP BY FLOOR(rowtime TO HOUR), productId;
+
+SELECT STREAM rowtime, productId
+FROM HourlyOrderTotals
+WHERE c > 2 OR su > 10;
+
+ rowtime | productId
+----------+-----------
+ 10:00:00 | 30
+ 11:00:00 | 10
+ 11:00:00 | 40
+{% endhighlight %}
+
+Sub-queries in the `FROM` clause are sometimes referred to as "inline views",
+but really, they are more fundamental than views. Views are just a convenient
+way to carve your SQL into manageable chunks by giving the pieces names and
+storing them in the metadata repository.
+
+Many people find that nested queries and views are even more useful on streams
+than they are on relations. Streaming queries are pipelines of
+operators all running continuously, and often those pipelines get quite long.
+Nested queries and views help to express and manage those pipelines.
+
+And, by the way, a `WITH` clause can accomplish the same as a sub-query or
+a view:
+
+{% highlight sql %}
+WITH HourlyOrderTotals (rowtime, productId, c, su) AS (
+ SELECT FLOOR(rowtime TO HOUR),
+ productId,
+ COUNT(*),
+ SUM(units)
+ FROM Orders
+ GROUP BY FLOOR(rowtime TO HOUR), productId)
+SELECT STREAM rowtime, productId
+FROM HourlyOrderTotals
+WHERE c > 2 OR su > 10;
+
+ rowtime | productId
+----------+-----------
+ 10:00:00 | 30
+ 11:00:00 | 10
+ 11:00:00 | 40
+{% endhighlight %}
+
+## Converting between streams and relations
+
+Look back at the definition of the `HourlyOrderTotals` view.
+Is the view a stream or a relation?
+
+It does not contain the `STREAM` keyword, so it is a relation.
+However, it is a relation that can be converted into a stream.
+
+You can use it in both relational and streaming queries:
+
+{% highlight sql %}
+# A relation; will query the historic Orders table.
+# Returns the largest number of product #10 ever sold in one hour.
+SELECT max(su)
+FROM HourlyOrderTotals
+WHERE productId = 10;
+
+# A stream; will query the Orders stream.
+# Returns every hour in which at least one product #10 was sold.
+SELECT STREAM rowtime
+FROM HourlyOrderTotals
+WHERE productId = 10;
+{% endhighlight %}
+
+This approach is not limited to views and sub-queries.
+Following the approach set out in CQL [<a href="#ref1">1</a>], every query
+in streaming SQL is defined as a relational query and converted to a stream
+using the `STREAM` keyword in the top-most `SELECT`.
+
+If the `STREAM` keyword is present in sub-queries or view definitions, it has no
+effect.
+
+At query preparation time, Calcite figures out whether the relations referenced
+in the query can be converted to streams or historical relations.
+
+Sometimes a stream makes available some of its history (say the last 24 hours of
+data in an Apache Kafka [<a href="#ref2">2</a>] topic)
+but not all. At run time, Calcite figures out whether there is sufficient
+history to run the query, and if not, gives an error.
+
+## Hopping windows
+
+Previously we saw how to define a tumbling window using a `GROUP BY` clause.
+Each record contributed to a single sub-total record, the one containing its
+hour and product id.
+
+But suppose we want to emit, every hour, the number of each product ordered over
+the past three hours. To do this, we use `SELECT ... OVER` and a sliding window
+to combine multiple tumbling windows.
+
+{% highlight sql %}
+SELECT STREAM rowtime,
+ productId,
+ SUM(su) OVER w AS su,
+ SUM(c) OVER w AS c
+FROM HourlyTotals
+WINDOW w AS (
+ ORDER BY rowtime
+ PARTITION BY productId
+ RANGE INTERVAL '2' HOUR PRECEDING)
+{% endhighlight %}
+
+This query uses the `HourlyOrderTotals` view defined previously.
+The 2 hour interval combines the totals timestamped 09:00:00, 10:00:00 and
+11:00:00 for a particular product into a single total timestamped 11:00:00 and
+summarizing orders for that product between 09:00:00 and 12:00:00.
+
+## Limitations of tumbling and hopping windows
+
+In the present syntax, we acknowledge that it is not easy to create certain
+kinds of windows.
+
+First, let's consider tumbling windows over complex periods.
+
+The `FLOOR` and `CEIL` functions make is easy to create a tumbling window that
+emits on a whole time unit (say every hour, or every minute) but less easy to
+emit, say, every 15 minutes. One could imagine an extension to the `FLOOR`
+function that emits unique values on just about any periodic basis (say in 11
+minute intervals starting from midnight of the current day).
+
+Next, let's consider hopping windows whose retention period is not a multiple
+of its emission period. Say we want to output, at the top of each hour, the
+orders for the previous 7,007 seconds. If we were to simulate this hopping
+window using a sliding window over a tumbling window, as before, we would have
+to sum lots of 1-second windows (because 3,600 and 7,007 are co-prime).
+This is a lot of effort for both the system and the person writing the query.
+
+Calcite could perhaps solve this generalizing `GROUP BY` syntax, but we would
+be destroying the principle that an input row into a `GROUP BY` appears in
+precisely one output row.
+
+Calcite's SQL extensions for streaming queries are evolving. As we learn more
+about how people wish to query streams, we plan to make the language more
+expressive while remaining compatible with standard SQL and consistent with
+its principles, look and feel.
+
+## Sorting
+
+The story for `ORDER BY` is similar to `GROUP BY`.
+The syntax looks like regular SQL, but Calcite must be sure that it can deliver
+timely results. It therefore requires a monotonic expression on the leading edge
+of your `ORDER BY` key.
+
+{% highlight sql %}
+SELECT STREAM FLOOR(rowtime TO hour) AS rowtime, productId, orderId, units
+FROM Orders
+ORDER BY FLOOR(rowtime TO hour) ASC, units DESC;
+
+ rowtime | productId | orderId | units
+----------+-----------+---------+-------
+ 10:00:00 | 30 | 8 | 20
+ 10:00:00 | 30 | 5 | 4
+ 10:00:00 | 20 | 7 | 2
+ 10:00:00 | 10 | 6 | 1
+ 11:00:00 | 40 | 11 | 12
+ 11:00:00 | 10 | 9 | 6
+ 11:00:00 | 10 | 12 | 4
+ 11:00:00 | 10 | 10 | 1
+{% endhighlight %}
+
+Most queries will return results in the order that they were inserted,
+because the engine is using streaming algorithms, but you should not rely on it.
+For example, consider this:
+
+{% highlight sql %}
+SELECT STREAM *
+FROM Orders
+WHERE productId = 10
+UNION ALL
+SELECT STREAM *
+FROM Orders
+WHERE productId = 30;
+
+ rowtime | productId | orderId | units
+----------+-----------+---------+-------
+ 10:17:05 | 10 | 6 | 1
+ 10:17:00 | 30 | 5 | 4
+ 10:18:07 | 30 | 8 | 20
+ 11:02:00 | 10 | 9 | 6
+ 11:04:00 | 10 | 10 | 1
+ 11:24:11 | 10 | 12 | 4
+{% endhighlight %}
+
+The rows with `productId` = 30 are apparently out of order, probably because
+the `Orders` stream was partitioned on `productId` and the partitioned streams
+sent their data at different times.
+
+If you require a particular ordering, add an explicit `ORDER BY`:
+
+{% highlight sql %}
+SELECT STREAM *
+FROM Orders
+WHERE productId = 10
+UNION ALL
+SELECT STREAM *
+FROM Orders
+WHERE productId = 30
+ORDER BY rowtime;
+
+ rowtime | productId | orderId | units
+----------+-----------+---------+-------
+ 10:17:00 | 30 | 5 | 4
+ 10:17:05 | 10 | 6 | 1
+ 10:18:07 | 30 | 8 | 20
+ 11:02:00 | 10 | 9 | 6
+ 11:04:00 | 10 | 10 | 1
+ 11:24:11 | 10 | 12 | 4
+{% endhighlight %}
+
+Calcite will probably implement the `UNION ALL` by merging using `rowtime`,
+which is only slightly less efficient.
+
+You only need to add an `ORDER BY` to the outermost query. If you need to,
+say, perform `GROUP BY` after a `UNION ALL`, Calcite will add an `ORDER BY`
+implicitly, in order to make the GROUP BY algorithm possible.
+
+## Table constructor
+
+The `VALUES` clause creates an inline table with a given set of rows.
+
+Streaming is disallowed. The set of rows never changes, and therefore a stream
+would never return any rows.
+
+{% highlight sql %}
+> SELECT STREAM * FROM (VALUES (1, 'abc'));
+
+ERROR: Cannot stream VALUES
+{% endhighlight %}
+
+## Sliding windows
+
+Standard SQL features so-called "analytic functions" that can be used in the
+`SELECT` clause. Unlike `GROUP BY`, these do not collapse records. For each
+record that goes in, one record comes out. But the aggregate function is based
+on a window of many rows.
+
+Let's look at an example.
+
+{% highlight sql %}
+SELECT STREAM rowtime,
+ productId,
+ units,
+ SUM(units) OVER (ORDER BY rowtime RANGE INTERVAL '1' HOUR PRECEDING) unitsLastHour
+FROM Orders;
+{% endhighlight %}
+
+The feature packs a lot of power with little effort. You can have multiple
+functions in the `SELECT` clause, based on multiple window specifications.
+
+The following example returns orders whose average order size over the last
+10 minutes is greater than the average order size for the last week.
+
+{% highlight sql %}
+SELECT STREAM *
+FROM (
+ SELECT STREAM rowtime,
+ productId,
+ units,
+ AVG(units) OVER product (RANGE INTERVAL '10' MINUTE PRECEDING) AS m10,
+ AVG(units) OVER product (RANGE INTERVAL '7' DAY PRECEDING) AS d7
+ FROM Orders
+ WINDOW product AS (
+ ORDER BY rowtime
+ PARTITION BY productId))
+WHERE m10 > d7;
+{% endhighlight %}
+
+For conciseness, here we use a syntax where you partially define a window
+using a `WINDOW` clause and then refine the window in each `OVER` clause.
+You could also define all windows in the `WINDOW` clause, or all windows inline,
+if you wish.
+
+But the real power goes beyond syntax. Behind the scenes, this query is
+maintaining two tables, and adding and removing values from sub-totals using
+with FIFO queues. But you can access those tables without introducing a join
+into the query.
+
+Some other features of the windowed aggregation syntax:
+
+* You can define windows based on row count.
+* The window can reference rows that have not yet arrived.
+ (The stream will wait until they have arrived).
+* You can compute order-dependent functions such as `RANK` and median.
+
+## Cascading windows
+
+What if we want a query that returns a result for every record, like a
+sliding window, but resets totals on a fixed time period, like a
+tumbling window? Such a pattern is called a *cascading window*. Here
+is an example:
+
+{% highlight sql %}
+SELECT STREAM rowtime,
+ productId,
+ units,
+ SUM(units) OVER (PARTITION BY FLOOR(rowtime TO HOUR)) AS unitsSinceTopOfHour
+FROM Orders;
+{% endhighlight %}
+
+It looks similar to a sliding window query, but the monotonic
+expression occurs within the `PARTITION BY` clause of the window. As
+the rowtime moves from from 10:59:59 to 11:00:00, `FLOOR(rowtime TO
+HOUR)` changes from 10:00:00 to 11:00:00, and therefore a new
+partition starts. The first row to arrive in the new hour will start a
+new total; the second row will have a total that consists of two rows,
+and so on.
+
+Calcite knows that the old partition will never be used again, so
+removes all sub-totals for that partition from its internal storage.
+
+Analytic functions that using cascading and sliding windows can be
+combined in the same query.
+
+## State of the stream
+
+Not all concepts in this article have been implemented in Calcite.
+And others may be implemented in Calcite but not in a particular adapter
+such as Samza SQL [<a href="#ref3">3</a>].
+
+### Implemented
+* Streaming SELECT, WHERE, GROUP BY, HAVING, UNION ALL, ORDER BY
+* FLOOR and CEILING functions
+* Monotonicity
+* Streaming VALUES is disallowed
+
+### Not implemented
+* Stream-to-stream JOIN
+* Stream-to-table JOIN
+* Stream on view
+* Streaming UNION ALL with ORDER BY (merge)
+* Relational query on stream
+* Streaming windowed aggregation (sliding and cascading windows)
+* Check that STREAM in sub-queries and views is ignored
+* Check that streaming ORDER BY cannot have OFFSET or LIMIT
+* Limited history; at run time, check that there is sufficient history
+ to run the query.
+
+### To do in this document
+* Re-visit whether you can stream VALUES
+* OVER clause to define window on stream
+* Windowed aggregation
+* Punctuation
+* Stream-to-table join
+ * Stream-to-table join where table is changing
+* Stream-to-stream join

+
+This is a step-by-step tutorial that shows how to build and connect to
+Calcite. It uses a simple adapter that makes a directory of CSV files
+appear to be a schema containing tables. Calcite does the rest, and
+provides a full SQL interface.
+
+Calcite-example-CSV is a fully functional adapter for
+Calcite that reads
+text files in
+<a href="http://en.wikipedia.org/wiki/Comma-separated_values">CSV
+(comma-separated values)</a> format. It is remarkable that a couple of
+hundred lines of Java code are sufficient to provide full SQL query
+capability.
+
+CSV also serves as a template for building adapters to other
+data formats. Even though there are not many lines of code, it covers
+several important concepts:
+
+* user-defined schema using SchemaFactory and Schema interfaces;
+* declaring schemas in a model JSON file;
+* declaring views in a model JSON file;
+* user-defined table using the Table interface;
+* determining the record type of a table;
+* a simple implementation of Table, using the ScannableTable interface, that
+ enumerates all rows directly;
+* a more advanced implementation that implements FilterableTable, and can
+ filter out rows according to simple predicates;
+* advanced implementation of Table, using TranslatableTable, that translates
+ to relational operators using planner rules.
+
+## Download and build
+
+You need Java (1.7 or higher; 1.8 preferred), git and maven (3.2.1 or later).
+
+{% highlight bash %}
+$ git clone https://github.com/apache/incubator-calcite.git
+$ cd incubator-calcite
+$ mvn install -DskipTests -Dcheckstyle.skip=true
+$ cd example/csv
+{% endhighlight %}
+
+## First queries
+
+Now let's connect to Calcite using
+<a href="https://github.com/julianhyde/sqlline">sqlline</a>, a SQL shell
+that is included in this project.
+
+{% highlight bash %}
+$ ./sqlline
+sqlline> !connect jdbc:calcite:model=target/test-classes/model.json admin admin
+{% endhighlight %}
+
+(If you are running Windows, the command is `sqlline.bat`.)
+
+Execute a metadata query:
+
+{% highlight bash %}
+sqlline> !tables
++------------+--------------+-------------+---------------+----------+------+
+| TABLE_CAT | TABLE_SCHEM | TABLE_NAME | TABLE_TYPE | REMARKS | TYPE |
++------------+--------------+-------------+---------------+----------+------+
+| null | SALES | DEPTS | TABLE | null | null |
+| null | SALES | EMPS | TABLE | null | null |
+| null | SALES | HOBBIES | TABLE | null | null |
+| null | metadata | COLUMNS | SYSTEM_TABLE | null | null |
+| null | metadata | TABLES | SYSTEM_TABLE | null | null |
++------------+--------------+-------------+---------------+----------+------+
+{% endhighlight %}
+
+(JDBC experts, note: sqlline's <code>!tables</code> command is just executing
+<a href="http://docs.oracle.com/javase/7/docs/api/java/sql/DatabaseMetaData.html#getTables(java.lang.String, java.lang.String, java.lang.String, java.lang.String[])"><code>DatabaseMetaData.getTables()</code></a>
+behind the scenes.
+It has other commands to query JDBC metadata, such as <code>!columns</code> and <code>!describe</code>.)
+
+As you can see there are 5 tables in the system: tables
+<code>EMPS</code>, <code>DEPTS</code> and <code>HOBBIES</code> in the current
+<code>SALES</code> schema, and <code>COLUMNS</code> and
+<code>TABLES</code> in the system <code>metadata</code> schema. The
+system tables are always present in Calcite, but the other tables are
+provided by the specific implementation of the schema; in this case,
+the <code>EMPS</code> and <code>DEPTS</code> tables are based on the
+<code>EMPS.csv</code> and <code>DEPTS.csv</code> files in the
+<code>target/test-classes</code> directory.
+
+Let's execute some queries on those tables, to show that Calcite is providing
+a full implementation of SQL. First, a table scan:
+
+{% highlight bash %}
+sqlline> SELECT * FROM emps;
++--------+--------+---------+---------+----------------+--------+-------+---+
+| EMPNO | NAME | DEPTNO | GENDER | CITY | EMPID | AGE | S |
++--------+--------+---------+---------+----------------+--------+-------+---+
+| 100 | Fred | 10 | | | 30 | 25 | t |
+| 110 | Eric | 20 | M | San Francisco | 3 | 80 | n |
+| 110 | John | 40 | M | Vancouver | 2 | null | f |
+| 120 | Wilma | 20 | F | | 1 | 5 | n |
+| 130 | Alice | 40 | F | Vancouver | 2 | null | f |
++--------+--------+---------+---------+----------------+--------+-------+---+
+{% endhighlight %}
+
+Now JOIN and GROUP BY:
+
+{% highlight bash %}
+sqlline> SELECT d.name, COUNT(*)
+. . . .> FROM emps AS e JOIN depts AS d ON e.deptno = d.deptno
+. . . .> GROUP BY d.name;
++------------+---------+
+| NAME | EXPR$1 |
++------------+---------+
+| Sales | 1 |
+| Marketing | 2 |
++------------+---------+
+{% endhighlight %}
+
+Last, the VALUES operator generates a single row, and is a convenient
+way to test expressions and SQL built-in functions:
+
+{% highlight bash %}
+sqlline> VALUES CHAR_LENGTH('Hello, ' || 'world!');
++---------+
+| EXPR$0 |
++---------+
+| 13 |
++---------+
+{% endhighlight %}
+
+Calcite has many other SQL features. We don't have time to cover them
+here. Write some more queries to experiment.
+
+## Schema discovery
+
+Now, how did Calcite find these tables? Remember, core Calcite does not
+know anything about CSV files. (As a "database without a storage
+layer", Calcite doesn't know about any file formats.) Calcite knows about
+those tables because we told it to run code in the calcite-example-csv
+project.
+
+There are a couple of steps in that chain. First, we define a schema
+based on a schema factory class in a model file. Then the schema
+factory creates a schema, and the schema creates several tables, each
+of which knows how to get data by scanning a CSV file. Last, after
+Calcite has parsed the query and planned it to use those tables, Calcite
+invokes the tables to read the data as the query is being
+executed. Now let's look at those steps in more detail.
+
+On the JDBC connect string we gave the path of a model in JSON
+format. Here is the model:
+
+{% highlight json %}
+{
+ version: '1.0',
+ defaultSchema: 'SALES',
+ schemas: [
+ {
+ name: 'SALES',
+ type: 'custom',
+ factory: 'org.apache.calcite.adapter.csv.CsvSchemaFactory',
+ operand: {
+ directory: 'target/test-classes/sales'
+ }
+ }
+ ]
+}
+{% endhighlight %}
+
+The model defines a single schema called 'SALES'. The schema is
+powered by a plugin class,
+<a href="{{ sourceRoot }}/example/csv/src/main/java/org/apache/calcite/adapter/csv/CsvSchemaFactory.java">org.apache.calcite.adapter.csv.CsvSchemaFactory</a>,
+which is part of the
+calcite-example-csv project and implements the Calcite interface
+<a href="/apidocs/org/apache/calcite/schema/SchemaFactory.html">SchemaFactory</a>.
+Its <code>create</code> method instantiates a
+schema, passing in the <code>directory</code> argument from the model file:
+
+{% highlight java %}
+public Schema create(SchemaPlus parentSchema, String name,
+ Map<String, Object> operand) {
+ String directory = (String) operand.get("directory");
+ String flavorName = (String) operand.get("flavor");
+ CsvTable.Flavor flavor;
+ if (flavorName == null) {
+ flavor = CsvTable.Flavor.SCANNABLE;
+ } else {
+ flavor = CsvTable.Flavor.valueOf(flavorName.toUpperCase());
+ }
+ return new CsvSchema(
+ new File(directory),
+ flavor);
+}
+{% endhighlight %}
+
+Driven by the model, the schema factory instantiates a single schema
+called 'SALES'. The schema is an instance of
+<a href="{{ sourceRoot }}/example/csv/src/main/java/org/apache/calcite/adapter/csv/CsvSchema.java">org.apache.calcite.adapter.csv.CsvSchema</a>
+and implements the Calcite interface
+<a href="/calcite/apidocs/org/apache/calcite/schema/Schema.html">Schema</a>.
+
+A schema's job is to produce a list of tables. (It can also list sub-schemas and
+table-functions, but these are advanced features and calcite-example-csv does
+not support them.) The tables implement Calcite's
+<a href="/apidocs/org/apache/calcite/schema/Table.html">Table</a>
+interface. <code>CsvSchema</code> produces tables that are instances of
+<a href="{{ sourceRoot }}/example/csv/src/main/java/org/apache/calcite/adapter/csv/CsvTable.java">CsvTable</a>
+and its sub-classes.
+
+Here is the relevant code from <code>CsvSchema</code>, overriding the
+<code><a href="/apidocs/org/apache/calcite/schema/impl/AbstractSchema.html#getTableMap()">getTableMap()</a></code>
+method in the <code>AbstractSchema</code> base class.
+
+{% highlight java %}
+protected Map<String, Table> getTableMap() {
+ // Look for files in the directory ending in ".csv", ".csv.gz", ".json",
+ // ".json.gz".
+ File[] files = directoryFile.listFiles(
+ new FilenameFilter() {
+ public boolean accept(File dir, String name) {
+ final String nameSansGz = trim(name, ".gz");
+ return nameSansGz.endsWith(".csv")
+ || nameSansGz.endsWith(".json");
+ }
+ });
+ if (files == null) {
+ System.out.println("directory " + directoryFile + " not found");
+ files = new File[0];
+ }
+ // Build a map from table name to table; each file becomes a table.
+ final ImmutableMap.Builder<String, Table> builder = ImmutableMap.builder();
+ for (File file : files) {
+ String tableName = trim(file.getName(), ".gz");
+ final String tableNameSansJson = trimOrNull(tableName, ".json");
+ if (tableNameSansJson != null) {
+ JsonTable table = new JsonTable(file);
+ builder.put(tableNameSansJson, table);
+ continue;
+ }
+ tableName = trim(tableName, ".csv");
+ final Table table = createTable(file);
+ builder.put(tableName, table);
+ }
+ return builder.build();
+}
+
+/** Creates different sub-type of table based on the "flavor" attribute. */
+private Table createTable(File file) {
+ switch (flavor) {
+ case TRANSLATABLE:
+ return new CsvTranslatableTable(file, null);
+ case SCANNABLE:
+ return new CsvScannableTable(file, null);
+ case FILTERABLE:
+ return new CsvFilterableTable(file, null);
+ default:
+ throw new AssertionError("Unknown flavor " + flavor);
+ }
+}
+{% endhighlight %}
+
+The schema scans the directory and finds all files whose name ends
+with ".csv" and creates tables for them. In this case, the directory
+is <code>target/test-classes/sales</code> and contains files
+<code>EMPS.csv</code> and <code>DEPTS.csv</code>, which these become
+the tables <code>EMPS</code> and <code>DEPTS</code>.
+
+## Tables and views in schemas
+
+Note how we did not need to define any tables in the model; the schema
+generated the tables automatically.
+
+You can define extra tables,
+beyond those that are created automatically,
+using the <code>tables</code> property of a schema.
+
+Let's see how to create
+an important and useful type of table, namely a view.
+
+A view looks like a table when you are writing a query, but it doesn't store data.
+It derives its result by executing a query.
+The view is expanded while the query is being planned, so the query planner
+can often perform optimizations like removing expressions from the SELECT
+clause that are not used in the final result.
+
+Here is a schema that defines a view:
+
+{% highlight json %}
+{
+ version: '1.0',
+ defaultSchema: 'SALES',
+ schemas: [
+ {
+ name: 'SALES',
+ type: 'custom',
+ factory: 'org.apache.calcite.adapter.csv.CsvSchemaFactory',
+ operand: {
+ directory: 'target/test-classes/sales'
+ },
+ tables: [
+ {
+ name: 'FEMALE_EMPS',
+ type: 'view',
+ sql: 'SELECT * FROM emps WHERE gender = \'F\''
+ }
+ ]
+ }
+ ]
+}
+{% endhighlight %}
+
+The line <code>type: 'view'</code> tags <code>FEMALE_EMPS</code> as a view,
+as opposed to a regular table or a custom table.
+Note that single-quotes within the view definition are escaped using a
+back-slash, in the normal way for JSON.
+
+JSON doesn't make it easy to author long strings, so Calcite supports an
+alternative syntax. If your view has a long SQL statement, you can instead
+supply a list of lines rather than a single string:
+
+{% highlight json %}
+{
+ name: 'FEMALE_EMPS',
+ type: 'view',
+ sql: [
+ 'SELECT * FROM emps',
+ 'WHERE gender = \'F\''
+ ]
+}
+{% endhighlight %}
+
+Now we have defined a view, we can use it in queries just as if it were a table:
+
+{% highlight sql %}
+sqlline> SELECT e.name, d.name FROM female_emps AS e JOIN depts AS d on e.deptno = d.deptno;
++--------+------------+
+| NAME | NAME |
++--------+------------+
+| Wilma | Marketing |
++--------+------------+
+{% endhighlight %}
+
+## Custom tables
+
+Custom tables are tables whose implementation is driven by user-defined code.
+They don't need to live in a custom schema.
+
+There is an example in <code>model-with-custom-table.json</code>:
+
+{% highlight json %}
+{
+ version: '1.0',
+ defaultSchema: 'CUSTOM_TABLE',
+ schemas: [
+ {
+ name: 'CUSTOM_TABLE',
+ tables: [
+ {
+ name: 'EMPS',
+ type: 'custom',
+ factory: 'org.apache.calcite.adapter.csv.CsvTableFactory',
+ operand: {
+ file: 'target/test-classes/sales/EMPS.csv.gz',
+ flavor: "scannable"
+ }
+ }
+ ]
+ }
+ ]
+}
+{% endhighlight %}
+
+We can query the table in the usual way:
+
+{% highlight sql %}
+sqlline> !connect jdbc:calcite:model=target/test-classes/model-with-custom-table.json admin admin
+sqlline> SELECT empno, name FROM custom_table.emps;
++--------+--------+
+| EMPNO | NAME |
++--------+--------+
+| 100 | Fred |
+| 110 | Eric |
+| 110 | John |
+| 120 | Wilma |
+| 130 | Alice |
++--------+--------+
+{% endhighlight %}
+
+The schema is a regular one, and contains a custom table powered by
+<a href="{{ sourceRoot }}/example/csv/src/main/java/org/apache/calcite/adapter/csv/CsvTableFactory.java">org.apache.calcite.adapter.csv.CsvTableFactory</a>,
+which implements the Calcite interface
+<a href="/apidocs/org/apache/calcite/schema/TableFactory.html">TableFactory</a>.
+Its <code>create</code> method instantiates a <code>CsvScannableTable</code>,
+passing in the <code>file</code> argument from the model file:
+
+{% highlight java %}
+public CsvTable create(SchemaPlus schema, String name,
+ Map<String, Object> map, RelDataType rowType) {
+ String fileName = (String) map.get("file");
+ final File file = new File(fileName);
+ final RelProtoDataType protoRowType =
+ rowType != null ? RelDataTypeImpl.proto(rowType) : null;
+ return new CsvScannableTable(file, protoRowType);
+}
+{% endhighlight %}
+
+Implementing a custom table is often a simpler alternative to implementing
+a custom schema. Both approaches might end up creating a similar implementation
+of the <code>Table</code> interface, but for the custom table you don't
+need to implement metadata discovery. (<code>CsvTableFactory</code>
+creates a <code>CsvScannableTable</code>, just as <code>CsvSchema</code> does,
+but the table implementation does not scan the filesystem for .csv files.)
+
+Custom tables require more work for the author of the model (the author
+needs to specify each table and its file explicitly) but also give the author
+more control (say, providing different parameters for each table).
+
+## Comments in models
+
+Models can include comments using `/* ... */` and `//` syntax:
+
+{% highlight json %}
+{
+ version: '1.0',
+ /* Multi-line
+ comment. */
+ defaultSchema: 'CUSTOM_TABLE',
+ // Single-line comment.
+ schemas: [
+ ..
+ ]
+}
+{% endhighlight %}
+
+(Comments are not standard JSON, but are a harmless extension.)
+
+## Optimizing queries using planner rules
+
+The table implementations we have seen so far are fine as long as the tables
+don't contain a great deal of data. But if your customer table has, say, a
+hundred columns and a million rows, you would rather that the system did not
+retrieve all of the data for every query. You would like Calcite to negotiate
+with the adapter and find a more efficient way of accessing the data.
+
+This negotiation is a simple form of query optimization. Calcite supports query
+optimization by adding <i>planner rules</i>. Planner rules operate by
+looking for patterns in the query parse tree (for instance a project on top
+of a certain kind of table), and
+
+Planner rules are also extensible, like schemas and tables. So, if you have a
+data store that you want to access via SQL, you first define a custom table or
+schema, and then you define some rules to make the access efficient.
+
+To see this in action, let's use a planner rule to access
+a subset of columns from a CSV file. Let's run the same query against two very
+similar schemas:
+
+{% highlight sql %}
+sqlline> !connect jdbc:calcite:model=target/test-classes/model.json admin admin
+sqlline> explain plan for select name from emps;
++-----------------------------------------------------+
+| PLAN |
++-----------------------------------------------------+
+| EnumerableCalcRel(expr#0..9=[{inputs}], NAME=[$t1]) |
+| EnumerableTableAccessRel(table=[[SALES, EMPS]]) |
++-----------------------------------------------------+
+sqlline> !connect jdbc:calcite:model=target/test-classes/smart.json admin admin
+sqlline> explain plan for select name from emps;
++-----------------------------------------------------+
+| PLAN |
++-----------------------------------------------------+
+| EnumerableCalcRel(expr#0..9=[{inputs}], NAME=[$t1]) |
+| CsvTableScan(table=[[SALES, EMPS]]) |
++-----------------------------------------------------+
+{% endhighlight %}
+
+What causes the difference in plan? Let's follow the trail of evidence. In the
+<code>smart.json</code> model file, there is just one extra line:
+
+{% highlight json %}
+flavor: "translatable"
+{% endhighlight %}
+
+This causes a <code>CsvSchema</code> to be created with
+<code>flavor = TRANSLATABLE</code>,
+and its <code>createTable</code> method creates instances of
+<a href="{{ sourceRoot }}/example/csv/src/main/java/org/apache/calcite/adapter/csv/CsvTranslatableTable.java">CsvTranslatableTable</a>
+rather than a <code>CsvScannableTable</code>.
+
+<code>CsvTranslatableTable</code> implements the
+<code><a href="/apidocs/org/apache/calcite/schema/TranslatableTable.html#toRel()">TranslatableTable.toRel()</a></code>
+method to create
+<a href="{{ sourceRoot }}/example/csv/src/main/java/org/apache/calcite/adapter/csv/CsvTableScan.java">CsvTableScan</a>.
+Table scans are the leaves of a query operator tree.
+The usual implementation is
+<code><a href="/apidocs/org/apache/calcite/adapter/enumerable/EnumerableTableScan.html">EnumerableTableScan</a></code>,
+but we have created a distinctive sub-type that will cause rules to fire.
+
+Here is the rule in its entirety:
+
+{% highlight java %}
+public class CsvProjectTableScanRule extends RelOptRule {
+ public static final CsvProjectTableScanRule INSTANCE =
+ new CsvProjectTableScanRule();
+
+ private CsvProjectTableScanRule() {
+ super(
+ operand(Project.class,
+ operand(CsvTableScan.class, none())),
+ "CsvProjectTableScanRule");
+ }
+
+ @Override
+ public void onMatch(RelOptRuleCall call) {
+ final Project project = call.rel(0);
+ final CsvTableScan scan = call.rel(1);
+ int[] fields = getProjectFields(project.getProjects());
+ if (fields == null) {
+ // Project contains expressions more complex than just field references.
+ return;
+ }
+ call.transformTo(
+ new CsvTableScan(
+ scan.getCluster(),
+ scan.getTable(),
+ scan.csvTable,
+ fields));
+ }
+
+ private int[] getProjectFields(List<RexNode> exps) {
+ final int[] fields = new int[exps.size()];
+ for (int i = 0; i < exps.size(); i++) {
+ final RexNode exp = exps.get(i);
+ if (exp instanceof RexInputRef) {
+ fields[i] = ((RexInputRef) exp).getIndex();
+ } else {
+ return null; // not a simple projection
+ }
+ }
+ return fields;
+ }
+}
+{% endhighlight %}
+
+The constructor declares the pattern of relational expressions that will cause
+the rule to fire.
+
+The <code>onMatch</code> method generates a new relational expression and calls
+<code><a href="/apidocs/org/apache/calcite/plan/RelOptRuleCall.html#transformTo(org.apache.calcite.rel.RelNode)">RelOptRuleCall.transformTo()</a></code>
+to indicate that the rule has fired successfully.
+
+## The query optimization process
+
+There's a lot to say about how clever Calcite's query planner is, but we won't
+say it here. The cleverness is designed to take the burden off you, the writer
+of planner rules.
+
+First, Calcite doesn't fire rules in a prescribed order. The query optimization
+process follows many branches of a branching tree, just like a chess playing
+program examines many possible sequences of moves. If rules A and B both match a
+given section of the query operator tree, then Calcite can fire both.
+
+Second, Calcite uses cost in choosing between plans, but the cost model doesn't
+prevent rules from firing which may seem to be more expensive in the short term.
+
+Many optimizers have a linear optimization scheme. Faced with a choice between
+rule A and rule B, as above, such an optimizer needs to choose immediately. It
+might have a policy such as "apply rule A to the whole tree, then apply rule B
+to the whole tree", or apply a cost-based policy, applying the rule that
+produces the cheaper result.
+
+Calcite doesn't require such compromises.
+This makes it simple to combine various sets of rules.
+If, say you want to combine rules to recognize materialized views with rules to
+read from CSV and JDBC source systems, you just give Calcite the set of all
+rules and tell it to go at it.
+
+Calcite does use a cost model. The cost model decides which plan to ultimately
+use, and sometimes to prune the search tree to prevent the search space from
+exploding, but it never forces you to choose between rule A and rule B. This is
+important, because it avoids falling into local minima in the search space that
+are not actually optimal.
+
+Also (you guessed it) the cost model is pluggable, as are the table and query
+operator statistics it is based upon. But that can be a subject for later.
+
+## JDBC adapter
+
+The JDBC adapter maps a schema in a JDBC data source as a Calcite schema.
+
+For example, this schema reads from a MySQL "foodmart" database:
+
+{% highlight json %}
+{
+ version: '1.0',
+ defaultSchema: 'FOODMART',
+ schemas: [
+ {
+ name: 'FOODMART',
+ type: 'custom',
+ factory: 'org.apache.calcite.adapter.jdbc.JdbcSchema$Factory',
+ operand: {
+ jdbcDriver: 'com.mysql.jdbc.Driver',
+ jdbcUrl: 'jdbc:mysql://localhost/foodmart',
+ jdbcUser: 'foodmart',
+ jdbcPassword: 'foodmart'
+ }
+ }
+ ]
+}
+{% endhighlight %}
+
+(The FoodMart database will be familiar to those of you who have used
+the Mondrian OLAP engine, because it is Mondrian's main test data
+set. To load the data set, follow <a
+href="http://mondrian.pentaho.com/documentation/installation.php#2_Set_up_test_data">Mondrian's
+installation instructions</a>.)
+
+<b>Current limitations</b>: The JDBC adapter currently only pushes
+down table scan operations; all other processing (filtering, joins,
+aggregations and so forth) occurs within Calcite. Our goal is to push
+down as much processing as possible to the source system, translating
+syntax, data types and built-in functions as we go. If a Calcite query
+is based on tables from a single JDBC database, in principle the whole
+query should go to that database. If tables are from multiple JDBC
+sources, or a mixture of JDBC and non-JDBC, Calcite will use the most
+efficient distributed query approach that it can.
+
+## The cloning JDBC adapter
+
+The cloning JDBC adapter creates a hybrid database. The data is
+sourced from a JDBC database but is read into in-memory tables the
+first time each table is accessed. Calcite evaluates queries based on
+those in-memory tables, effectively a cache of the database.
+
+For example, the following model reads tables from a MySQL
+"foodmart" database:
+
+{% highlight json %}
+{
+ version: '1.0',
+ defaultSchema: 'FOODMART_CLONE',
+ schemas: [
+ {
+ name: 'FOODMART_CLONE',
+ type: 'custom',
+ factory: 'org.apache.calcite.adapter.clone.CloneSchema$Factory',
+ operand: {
+ jdbcDriver: 'com.mysql.jdbc.Driver',
+ jdbcUrl: 'jdbc:mysql://localhost/foodmart',
+ jdbcUser: 'foodmart',
+ jdbcPassword: 'foodmart'
+ }
+ }
+ ]
+}
+{% endhighlight %}
+
+Another technique is to build a clone schema on top of an existing
+schema. You use the <code>source</code> property to reference a schema
+defined earlier in the model, like this:
+
+{% highlight json %}
+{
+ version: '1.0',
+ defaultSchema: 'FOODMART_CLONE',
+ schemas: [
+ {
+ name: 'FOODMART',
+ type: 'custom',
+ factory: 'org.apache.calcite.adapter.jdbc.JdbcSchema$Factory',
+ operand: {
+ jdbcDriver: 'com.mysql.jdbc.Driver',
+ jdbcUrl: 'jdbc:mysql://localhost/foodmart',
+ jdbcUser: 'foodmart',
+ jdbcPassword: 'foodmart'
+ }
+ },
+ {
+ name: 'FOODMART_CLONE',
+ type: 'custom',
+ factory: 'org.apache.calcite.adapter.clone.CloneSchema$Factory',
+ operand: {
+ source: 'FOODMART'
+ }
+ }
+ ]
+}
+{% endhighlight %}
+
+You can use this approach to create a clone schema on any type of
+schema, not just JDBC.
+
+The cloning adapter isn't the be-all and end-all. We plan to develop
+more sophisticated caching strategies, and a more complete and
+efficient implementation of in-memory tables, but for now the cloning
+JDBC adapter shows what is possible and allows us to try out our
+initial implementations.

+before you move on to 1.0.

+
+Calcite's first major release.
+
+Since the previous release we have re-organized the into the `org.apache.calcite`
+namespace. To make migration of your code easier, we have described the
+<a href="https://issues.apache.org/jira/secure/attachment/12681620/mapping.txt">mapping from old to new class names</a>
+as an attachment to
+[<a href="https://issues.apache.org/jira/browse/CALCITE-296">CALCITE-296</a>].
+
+The release adds SQL support for `GROUPING SETS`, `EXTEND`, `UPSERT` and sequences;
+a remote JDBC driver;
+improvements to the planner engine and built-in planner rules;
+improvements to the algorithms that implement the relational algebra,
+including an interpreter that can evaluate queries without compilation;
+and fixes about 30 bugs.

+
+This Calcite release makes it possible to exploit physical properties
+of relational expressions to produce more efficient plans, introducing
+collation and distribution as traits, `Exchange` relational operator,
+and several new forms of metadata.
+
+We add experimental support for streaming SQL.
+
+This release drops support for JDK 1.6; Calcite now requires 1.7 or
+later.
+
+We have introduced static `create` methods for many sub-classes of
+`RelNode`. We strongly suggest that you use these rather than
+calling constructors directly.

+
+A short release, less than a month after 1.1.
+
+There have been many changes to Avatica, hugely improving its coverage of the
+JDBC API and overall robustness. A new provider, `JdbcMeta`, allows
+you to remote an existing JDBC driver.
+
+[<a href="https://issues.apache.org/jira/browse/CALCITE-606">CALCITE-606</a>]
+improves how the planner propagates traits such as collation and
+distribution among relational expressions.
+
+[<a href="https://issues.apache.org/jira/browse/CALCITE-613">CALCITE-613</a>]
+and [<a href="https://issues.apache.org/jira/browse/CALCITE-307">CALCITE-307</a>]
+improve implicit and explicit conversions in SQL.

Apache Calcite is a dynamic data management framework.
-It was formerly called Optiq.
-
-## Getting Calcite
-
-To run Apache Calcite, you can either
-[download and build from github](doc/howto.md#building-from-git),
-or [download a release](http://www.apache.org/dyn/closer.cgi/incubator/calcite)
-then [build the source code](doc/howto.md#building-from-a-source-distribution).
-
-Pre-built jars are in
-[the Apache maven repository](https://repository.apache.org/content/repositories/releases)
-with the following Maven coordinates:
-
-```xml
-<dependency>
- <groupId>org.apache.calcite</groupId>
- <artifactId>calcite-core</artifactId>
- <version>1.3.0-incubating</version>
-</dependency>
-```
-
-## Example
-
-Calcite makes data anywhere, of any format, look like a database. For
-example, you can execute a complex ANSI-standard SQL statement on
-in-memory collections:
-
-```java
-public static class HrSchema {
- public final Employee[] emps = ... ;
- public final Department[] depts = ...;
-}
-
-Class.forName("org.apache.calcite.jdbc.Driver");
-Properties info = new Properties();
-info.setProperty("lex", "JAVA");
-Connection connection = DriverManager.getConnection("jdbc:calcite:", info);
-CalciteConnection calciteConnection =
- connection.unwrap(CalciteConnection.class);
-ReflectiveSchema.create(calciteConnection,
- calciteConnection.getRootSchema(), "hr", new HrSchema());
-Statement statement = calciteConnection.createStatement();
-ResultSet resultSet = statement.executeQuery(
- "select d.deptno, min(e.empid)\n"
- + "from hr.emps as e\n"
- + "join hr.depts as d\n"
- + " on e.deptno = d.deptno\n"
- + "group by d.deptno\n"
- + "having count(*) > 1");
-print(resultSet);
-resultSet.close();
-statement.close();
-connection.close();
-```
-
-Where is the database? There is no database. The connection is
-completely empty until <code>ReflectiveSchema.create</code> registers
-a Java object as a schema and its collection fields <code>emps</code>
-and <code>depts</code> as tables.
-
-Calcite does not want to own data; it does not even have favorite data
-format. This example used in-memory data sets, and processed them
-using operators such as <code>groupBy</code> and <code>join</code>
-from the linq4j
-library. But Calcite can also process data in other data formats, such
-as JDBC. In the first example, replace
-
-```java
-ReflectiveSchema.create(calciteConnection,
- calciteConnection.getRootSchema(), "hr", new HrSchema());
-```
-
-with
-
-```java
-Class.forName("com.mysql.jdbc.Driver");
-BasicDataSource dataSource = new BasicDataSource();
-dataSource.setUrl("jdbc:mysql://localhost");
-dataSource.setUsername("username");
-dataSource.setPassword("password");
-JdbcSchema.create(calciteConnection.getRootSchema(), "name", dataSource,
- null, "hr");
-```
-
-and Calcite will execute the same query in JDBC. To the application, the
-data and API are the same, but behind the scenes the implementation is
-very different. Calcite uses optimizer rules
-to push the <code>JOIN</code> and <code>GROUP BY</code> operations to
-the source database.
-
-In-memory and JDBC are just two familiar examples. Calcite can handle
-any data source and data format. To add a data source, you need to
-write an adapter that tells Calcite
-what collections in the data source it should consider "tables".
-
-For more advanced integration, you can write optimizer
-rules. Optimizer rules allow Calcite to access data of a new format,
-allow you to register new operators (such as a better join algorithm),
-and allow Calcite to optimize how queries are translated to
-operators. Calcite will combine your rules and operators with built-in
-rules and operators, apply cost-based optimization, and generate an
-efficient plan.
-
-### Non-JDBC access
-
-Calcite also allows front-ends other than SQL/JDBC. For example, you can
-execute queries in <a href="https://github.com/julianhyde/linq4j">linq4j</a>:
-
-```java
-final OptiqConnection connection = ...;
-ParameterExpression c = Expressions.parameter(Customer.class, "c");
-for (Customer customer
- : connection.getRootSchema()
- .getSubSchema("foodmart")
- .getTable("customer", Customer.class)
- .where(
- Expressions.<Predicate1<Customer>>lambda(
- Expressions.lessThan(
- Expressions.field(c, "customer_id"),
- Expressions.constant(5)),
- c))) {
- System.out.println(c.name);
-}
-```
-
-Linq4j understands the full query parse tree, and the Linq4j query
-provider for Calcite invokes Calcite as an query optimizer. If the
-<code>customer</code> table comes from a JDBC database (based on
-this code fragment, we really can't tell) then the optimal plan
-will be to send the query
-
-```SQL
-SELECT *
-FROM "customer"
-WHERE "customer_id" < 5
-```
-
-to the JDBC data source.
-
-### Writing an adapter
-
-The subproject under example/csv provides a CSV adapter, which is fully functional for use in applications
-but is also simple enough to serve as a good template if you are writing
-your own adapter.
-
-See the <a href="https://github.com/apache/incubator-calcite/blob/master/doc/tutorial.md">CSV tutorial</a>
-for information on using the CSV adapter and writing other adapters.
-
-See the <a href="doc/howto.md">HOWTO</a> for more information about using other
-adapters, and about using Calcite in general.
-

-The following features are complete.
-
-* Query parser, validator and optimizer

-## Disclaimer
-
-Apache Calcite is an effort undergoing incubation at The Apache Software
-Foundation (ASF), sponsored by the Apache Incubator. Incubation is
-required of all newly accepted projects until a further review
-indicates that the infrastructure, communications, and decision making
-process have stabilized in a manner consistent with other successful
-ASF projects. While incubation status is not necessarily a reflection
-of the completeness or stability of the code, it does indicate that
-the project has yet to be fully endorsed by the ASF.

-# Avatica
-
-## Introduction
-
-Avatica is a framework for building JDBC and ODBC drivers for databases,
-and an RPC wire protocol.
-
-![Avatica Architecture]
-(https://raw.githubusercontent.com/julianhyde/share/master/slides/avatica-architecture.png)
-
-Avatica's Java binding has very few dependencies.
-Even though it is part of Apache Calcite it does not depend on other parts of
-Calcite. It depends only on JDK 1.7+ and Jackson.
-
-Avatica's wire protocol is JSON over HTTP.
-The Java implementation uses Jackson to convert request/response command
-objects to/from JSON.
-
-Avatica-Server is a Java implementation of Avatica RPC.
-It embeds the Jetty HTTP server.
-
-Core concepts:
-* Meta is a local API sufficient to implement any Avatica provider
-* Factory creates implementations of the JDBC classes (Driver, Connection,
- Statement, ResultSet) on top of a Meta
-* Service is an interface that implements the functions of Meta in terms
- of request and response command objects
-
-## JDBC
-
-Avatica implements JDBC by means of Factory.
-Factory creates implementations of the JDBC classes (Driver, Connection,
-Statement, PreparedStatement, ResultSet) on top of a Meta.
-
-## ODBC
-
-Work has not started on Avatica ODBC.
-
-Avatica ODBC would use the same wire protocol and could use the same server
-implementation in Java. The ODBC client would be written in C or C++.
-
-Since the Avatica protocol abstracts many of the differences between providers,
-the same ODBC client could be used for different databases.
-
-## Project structure
-
-We know that it is important that client libraries have minimal dependencies.
-
-Avatica is currently part of Apache Calcite.
-It does not depend upon any other part of Calcite.
-At some point Avatica could become a separate project.
-
-Packages:
-* [org.apache.calcite.avatica](http://www.hydromatic.net/calcite/apidocs/org/apache/calcite/avatica/package-summary.html) Core framework
-* [org.apache.calcite.avatica.remote](http://www.hydromatic.net/calcite/apidocs/org/apache/calcite/avatica/remote/package-summary.html) JDBC driver that uses remote procedure calls
-* [org.apache.calcite.avatica.server](http://www.hydromatic.net/calcite/apidocs/org/apache/calcite/avatica/server/package-summary.html) HTTP server
-* [org.apache.calcite.avatica.util](http://www.hydromatic.net/calcite/apidocs/org/apache/calcite/avatica/util/package-summary.html) Utilities
-
-## Status
-
-### Implemented

-* RPC using JSON over HTTP
-* Local implementation
-* Implementation over an existing JDBC driver
-* Composite RPCs (combining several requests into one round trip)

-
-### Not implemented
-* ODBC
-* RPCs
- * CloseStatement
- * CloseConnection

-
-This Calcite release makes it possible to exploit physical properties
-of relational expressions to produce more efficient plans, introducing
-collation and distribution as traits, `Exchange` relational operator,
-and several new forms of metadata.
-
-We add experimental support for streaming SQL.
-
-This release drops support for JDK 1.6; Calcite now requires 1.7 or
-later.
-
-We have introduced static `create` methods for many sub-classes of
-`RelNode`. We strongly suggest that you use these rather than
-calling constructors directly.

- SQL parser should allow different identifier quoting
- * [<a href="https://issues.apache.org/jira/browse/CALCITE-34">CALCITE-34</a>]
- Policy for case-sensitivity of identifiers should be configurable
- * New connect-string parameter "lex", with allowable values
- "ORACLE", "MYSQL", "SQL_SERVER", "JAVA" sets policy to be like those
- databases, in terms of quote string, whether quoted and unquoted
- identifiers are converted to upper/lower case, and whether
- identifiers are matched case-sensitively. "JAVA" is case-sensitive,
- even for unquoted identifiers. It should be possible
- for each connection to have its own settings for these. Objects
- shared between sessions (views, materialized views) might
- require more work.
- * Added various internals to make it easy for developers to do the
- right thing. When you need to look up a schema, table or
- column/field name, you should use a catalog reader, and it will
- apply the right case-sensitivity policy.
- * Enable optiq consumer to utilize different lexical settings in
- Frameworks/Planner. (Jacques Nadeau)
-* [<a href="https://issues.apache.org/jira/browse/CALCITE-135">CALCITE-115</a>]

- * Remove references to VolcanoCost from RelSubset, so clients can
- use a different `RelOptCost`. (Harish Butani)
- * Make `VolcanoCost` immutable.
-* Break `SqlTypeStrategies` into `OperandTypes`, `ReturnTypes` and
- `InferTypes`, and rename its static members to upper-case, per

-* [<a href="https://issues.apache.org/jira/browse/CALCITE-113">CALCITE-113</a>]
- User-defined scalar functions
-* Add rules to short-cut a query if `LIMIT 0` is present. Also remove
- sort, aggregation, join if their inputs are known to be empty, and
- propagate the fact that the relational expressions are known to be
- empty up the tree. (We already do this for union, filter, project.)

-* Add maven-checkstyle-plugin, enable in "verify" phase, and fix exceptions.
-* Fix `SqlValidator` to rely on `RelDataType` to do field name matching. Fix
- `RelDataTypeImpl` to correctly use the case sensitive flag rather than
- ignoring it.
-* [<a href="https://issues.apache.org/jira/browse/CALCITE-119">CALCITE-119</a>]
- Comparing Java type long with SQL type INTEGER gives wrong answer
-* Enable multi-threaded testing, and fix race conditions.

-* [<a href="https://issues.apache.org/jira/browse/CALCITE-106">CALCITE-106</a>]
- Make `Schema` and `Table` SPIs simpler to implement, and make them
- re-usable across connections
- (**This is a breaking change**.)
-* Make it easier to define sub-classes of rule operands. The new class
- `RelOptRuleOperandChildren` contains the children of an operand and
- the policy for dealing with them. Existing rules now use the new
- methods to construct operands: `operand()`, `leaf()`, `any()`, `none()`,
- `unordered()`. The previous methods are now deprecated and will be
- removed before 0.4.18. (**This is a breaking change**.)
-* [<a href="https://issues.apache.org/jira/browse/CALCITE-101">CALCITE-101</a>]

- remove `subList`, `butLast`.
-* Convert `SqlIdentifier.names` from `String[]` to `ImmutableList<String>`.
-* Rename `OptiqAssert.assertThat()` to `that()`, to avoid clash with junit's

- Externalize RelNode to and from JSON
-
-Tuning
-* If `EnumerableAggregateRel` has no aggregate functions, generate a
- call to `Enumerable.distinct()`, thereby saving the effort of
- building trivial accumulators.
-* Default rule set now does not introduce `CalcRel` until a later phase
- of planning. This reduces the number of trivial projects and calcs
- created, merged, and elimated.
-* Reduce the amount of time spent creating record types that
- already exist.
-* More efficient implementation of `Util.isDistinct` for small lists.
-* When an internal record has 0 fields, rather than generating a
- synthetic class and lots of instances that are all the same, use the
- new `Unit` class, which is a singleton.
-* To take advantage of asymmetric hash join added recently in linq4j,
- tweak cost of `EnumerableJoinRel` so that join is cheaper if the
- larger input is on the left, and more expensive if it is a cartesian
- product.
-* [<a href="https://issues.apache.org/jira/browse/CALCITE-70">CALCITE-70</a>]
- Joins seem to be very expensive in memory
-* Make planning process more efficient by not sorting the list of
- matched rules each cycle. It is sorted if tracing is enabled;
- otherwise we scan to find the most important element. For this list,
- replace `LinkedList` with `ChunkList`, which has an O(1) remove and add,
- a fast O(n) get, and fast scan.

- together via many-to-one relationships. The queries that define
- materializations and end-user queries are canonized in terms of star tables.
- Matching (not done yet) will then be a matter of looking for sort, groupBy,
- project. It is not yet possible to define a star in an Optiq model file.
-* Add section to <a href="howto.md">HOWTO</a> on implementing adapters.
-* Fix data type conversions when creating a clone table in memory.
-* Fix how strings are escaped in JsonBuilder.
-* Test suite now depends on an embedded hsqldb database, so you can run
- <code>mvn test</code> right after pulling from git. You can instead use a
- MySQL database if you specify '-Dcalcite.test.db=mysql', but you need to
- manually populate it.
-* Fix a planner issue which occurs when the left and right children of join are
- the same relational expression, caused by a self-join query.
-* [<a href="https://issues.apache.org/jira/browse/CALCITE-76">CALCITE-76</a>]
- Precedence of the item operator, <code>map[index]</code>; remove the space
- before '[' when converting parse tree to string.
-* Allow <code>CAST(expression AS ANY)</code>, and fix an issue with the ANY type
- and NULL values.
-* Handle null timestamps and dates coming out of JDBC adapter.
-* Add <code>jdbcDriver</code> attribute to JDBC schema in model, for drivers
- that do not auto-register.
-* Allow join rules to match any subclass of JoinRelBase.
-* Push projects, filters and sorts down to MongoDB. (Fixes
- [<a href="https://issues.apache.org/jira/browse/CALCITE-57">CALCITE-57</a>],
- [<a href="https://issues.apache.org/jira/browse/CALCITE-60">CALCITE-60</a>] and
- [<a href="https://issues.apache.org/jira/browse/CALCITE-72">CALCITE-72</a>].)
-* Add instructions for loading FoodMart data set into MongoDB, and how to enable
- tracing.
-* Now runs on JDK 1.8 (still runs on JDK 1.6 and JDK 1.7).
-* Upgrade to junit-4.11 (avoiding the dodgy junit-4.1.12).
-* Upgrade to linq4j-0.1.11.
-
-## <a href="https://github.com/apache/incubator-calcite/releases/tag/optiq-parent-0.4.15">0.4.15</a> / 2013-10-14
-
-* Lots of good stuff that this margin is too small to contain. See
- <a href="reference.md">SQL language reference</a> and
- <a href="model.md">JSON model reference</a>.
-

+Here's some miscellaneous documentation about using Calcite and its various
+adapters.
+
+## Building from a source distribution
+
+Prerequisites are maven (3.2.1 or later)
+and Java (JDK 1.7 or later, 1.8 preferred) on your path.
+
+Unpack the source distribution `.tar.gz` or `.zip` file,
+`cd` to the root directory of the unpacked source,
+then build using maven:
+
+{% highlight bash %}
+$ tar xvfz calcite-1.3.0-incubating-source.tar.gz
+$ cd calcite-1.3.0-incubating
+$ mvn install
+{% endhighlight %}
+
+[Running tests](#running-tests) describes how to run more or fewer
+tests.
+
+## Building from git
+
+Prerequisites are git, maven (3.2.1 or later)
+and Java (JDK 1.7 or later, 1.8 preferred) on your path.
+
+Create a local copy of the github repository,
+`cd` to its root directory,
+then build using maven:
+
+{% highlight bash %}
+$ git clone git://github.com/apache/incubator-calcite.git
+$ cd incubator-calcite
+$ mvn install
+{% endhighlight %}
+
+[Running tests](#running-tests) describes how to run more or fewer
+tests.
+
+## Running tests
+
+The test suite will run by default when you build, unless you specify
+`-DskipTests`:
+
+{% highlight bash %}
+# Note: "mvn clean install" does not work; use "mvn clean" then "mvn install"
+$ mvn clean
+$ mvn -DskipTests install
+{% endhighlight %}
+
+There are other options that control which tests are run, and in what
+environment, as follows.
+
+* `-Dcalcite.test.db=DB` (where db is `h2`, `hsqldb`, `mysql`, or `postgresql`) allows you
+ to change the JDBC data source for the test suite. Calcite's test
+ suite requires a JDBC data source populated with the foodmart data
+ set.
+ * `hsqldb`, the default, uses an in-memory hsqldb database.
+ * All others access a test virtual machine
+ (see [integration tests](#running-integration-tests) below).
+ `mysql` and `postgresql` might be somewhat faster than hsqldb, but you need
+ to populate it (i.e. provision a VM).
+* `-Dcalcite.debug` prints extra debugging information to stdout.
+* `-Dcalcite.test.slow` enables tests that take longer to execute. For
+ example, there are tests that create virtual TPC-H and TPC-DS schemas
+ in-memory and run tests from those benchmarks.
+* `-Dcalcite.test.splunk=true` enables tests that run against Splunk.
+ Splunk must be installed and running.
+
+## Running integration tests
+
+For testing Calcite's external adapters, a test virtual machine should be used.
+The VM includes H2, HSQLDB, MySQL, MongoDB, and PostgreSQL.
+
+Test VM requires 5GiB of disk space and it takes 30 minutes to build.
+
+Note: you can use [calcite-test-dataset](https://github.com/vlsi/calcite-test-dataset)
+ to populate your own database, however it is recommended to use test VM so the test environment can be reproduced.
+
+### VM preparation
+
+0) Install dependencies: [Vagrant](https://www.vagrantup.com/) and [VirtualBox](https://www.virtualbox.org/)
+
+1) Clone https://github.com/vlsi/calcite-test-dataset.git at the same level as calcite repository.
+For instance:
+
+{% highlight bash %}
+code
+ +-- calcite
+ +-- calcite-test-dataset
+{% endhighlight %}
+
+Note: integration tests search for ../calcite-test-dataset or ../../calcite-test-dataset.
+ You can specify full path via calcite.test.dataset system property.
+
+2) Build and start the VM:
+
+{% highlight bash %}
+cd calcite-test-dataset && mvn install
+{% endhighlight %}
+
+### VM management
+
+Test VM is provisioned by Vagrant, so regular Vagrant `vagrant up` and `vagrant halt` should be used to start and stop the VM.
+The connection strings for different databases are listed in [calcite-test-dataset](https://github.com/vlsi/calcite-test-dataset) readme.
+
+### Suggested test flow
+
+Note: test VM should be started before you launch integration tests. Calcite itself does not start/stop the VM.
+
+Command line:
+
+* Executing regular unit tests (does not require external data): no change. `mvn test` or `mvn install`.
+* Executing all tests, for all the DBs: `mvn verify -Pit`. `it` stands for "integration-test". `mvn install -Pit` works as well.
+* Executing just tests for external DBs, excluding unit tests: `mvn -Dtest=foo -DfailIfNoTests=false -Pit verify`
+* Executing just MongoDB tests: `cd mongo; mvn verify -Pit`
+
+From within IDE:
+
+* Executing regular unit tests: no change.
+* Executing MongoDB tests: run `MongoAdapterIT.java` as usual (no additional properties are required)
+* Executing MySQL tests: run `JdbcTest` and `JdbcAdapterTest` with setting `-Dcalcite.test.db=mysql`
+* Executing PostgreSQL tests: run `JdbcTest` and `JdbcAdapterTest` with setting `-Dcalcite.test.db=postgresql`
+
+### Integration tests technical details
+
+Tests with external data are executed at maven's integration-test phase.
+We do not currently use pre-integration-test/post-integration-test, however we could use that in future.
+The verification of build pass/failure is performed at verify phase.
+Integration tests should be named `...IT.java`, so they are not picked up on unit test execution.
+
+## Contributing
+
+We welcome contributions.
+
+If you are planning to make a large contribution, talk to us first! It
+helps to agree on the general approach. Log a
+[JIRA case](https://issues.apache.org/jira/browse/CALCITE) for your
+proposed feature or start a discussion on the dev list.
+
+Fork the github repository, and create a branch for your feature.
+
+Develop your feature and test cases, and make sure that `mvn
+install` succeeds. (Run extra tests if your change warrants it.)
+
+Commit your change to your branch, and use a comment that starts with
+the JIRA case number, like this:
+
+`[CALCITE-345] AssertionError in RexToLixTranslator comparing to date literal`
+
+If your change had multiple commits, use `git rebase -i master` to
+combine them into a single commit, and to bring your code up to date
+with the latest on the main line.
+
+Then push your commit(s) to github, and create a pull request from
+your branch to the incubator-calcite master branch. Update the JIRA case
+to reference your pull request, and a committer will review your
+changes.
+
+## Getting started
+
+Calcite is a community, so the first step to joining the project is to introduce yourself.
+Join the [developers list](http://mail-archives.apache.org/mod_mbox/incubator-calcite-dev/)
+and send an email.
+
+If you have the chance to attend a [meetup](http://www.meetup.com/Apache-Calcite/),
+or meet [members of the community](http://calcite.incubator.apache.org/team-list.html)
+at a conference, that's also great.
+
+Choose an initial task to work on. It should be something really simple,
+such as a bug fix or a [Jira task that we have labeled
+"newbie"](https://issues.apache.org/jira/issues/?jql=labels%20%3D%20newbie%20%26%20project%20%3D%20Calcite%20%26%20status%20%3D%20Open).
+Follow the [contributing guidelines](#contributing) to get your change committed.
+
+After you have made several useful contributions we may
+[invite you to become a committer](https://community.apache.org/contributors/).
+We value all contributions that help to build a vibrant community, not just code.
+You can contribute by testing the code, helping verify a release,
+writing documentation or the web site,
+or just by answering questions on the list.
+
+## Tracing
+
+To enable tracing, add the following flags to the java command line:
+
+`-Dcalcite.debug=true -Djava.util.logging.config.file=core/src/test/resources/logging.properties`
+
+The first flag causes Calcite to print the Java code it generates
+(to execute queries) to stdout. It is especially useful if you are debugging
+mysterious problems like this:
+
+`Exception in thread "main" java.lang.ClassCastException: Integer cannot be cast to Long
+ at Baz$1$1.current(Unknown Source)`
+
+The second flag specifies a config file for
+the <a href="http://docs.oracle.com/javase/7/docs/api/java/util/logging/package-summary.html">java.util.logging</a>
+framework. Put the following into core/src/test/resources/logging.properties:
+
+{% highlight properties %}
+handlers= java.util.logging.ConsoleHandler
+.level= INFO
+org.apache.calcite.plan.RelOptPlanner.level=FINER
+java.util.logging.ConsoleHandler.level=ALL
+{% endhighlight %}
+
+The line `org.apache.calcite.plan.RelOptPlanner.level=FINER` tells the planner to produce
+fairly verbose output. You can modify the file to enable other loggers, or to change levels.
+For instance, if you change `FINER` to `FINEST` the planner will give you an account of the
+planning process so detailed that it might fill up your hard drive.
+
+## CSV adapter
+
+See the [tutorial](/docs/tutorial.html).
+
+## MongoDB adapter
+
+First, download and install Calcite,
+and <a href="http://www.mongodb.org/downloads">install MongoDB</a>.
+
+Note: you can use MongoDB from integration test virtual machine above.
+
+Import MongoDB's zipcode data set into MongoDB:
+
+{% highlight bash %}
+$ curl -o /tmp/zips.json http://media.mongodb.org/zips.json
+$ mongoimport --db test --collection zips --file /tmp/zips.json
+Tue Jun 4 16:24:14.190 check 9 29470
+Tue Jun 4 16:24:14.469 imported 29470 objects
+{% endhighlight %}
+
+Log into MongoDB to check it's there:
+
+{% highlight bash %}
+$ mongo
+MongoDB shell version: 2.4.3
+connecting to: test
+> db.zips.find().limit(3)
+{ "city" : "ACMAR", "loc" : [ -86.51557, 33.584132 ], "pop" : 6055, "state" : "AL", "_id" : "35004" }
+{ "city" : "ADAMSVILLE", "loc" : [ -86.959727, 33.588437 ], "pop" : 10616, "state" : "AL", "_id" : "35005" }

+
+## Splunk adapter
+
+To run the test suite and sample queries against Splunk,
+load Splunk's `tutorialdata.zip` data set as described in
+<a href="http://docs.splunk.com/Documentation/Splunk/6.0.2/PivotTutorial/GetthetutorialdataintoSplunk">the Splunk tutorial</a>.
+
+(This step is optional, but it provides some interesting data for the sample
+queries. It is also necessary if you intend to run the test suite, using
+`-Dcalcite.test.splunk=true`.)
+
+## Implementing an adapter
+
+New adapters can be created by implementing `CalcitePrepare.Context`:
+
+{% highlight java %}
+import org.apache.calcite.adapter.java.JavaTypeFactory;
+import org.apache.calcite.jdbc.CalcitePrepare;
+import org.apache.calcite.jdbc.CalciteRootSchema;
+
+public class AdapterContext implements CalcitePrepare.Context {
+ @Override
+ public JavaTypeFactory getTypeFactory() {
+ // adapter implementation
+ return typeFactory;
+ }
+
+ @Override
+ public CalciteRootSchema getRootSchema() {
+ // adapter implementation
+ return rootSchema;
+ }
+}
+{% endhighlight %}
+
+### Testing adapter in Java
+
+The example below shows how SQL query can be submitted to
+`CalcitePrepare` with a custom context (`AdapterContext` in this
+case). Calcite prepares and implements the query execution, using the
+resources provided by the `Context`. `CalcitePrepare.PrepareResult`
+provides access to the underlying enumerable and methods for
+enumeration. The enumerable itself can naturally be some adapter
+specific implementation.
+
+{% highlight java %}
+import org.apache.calcite.jdbc.CalcitePrepare;
+import org.apache.calcite.prepare.CalcitePrepareImpl;
+import org.junit.Test;
+
+public class AdapterContextTest {
+ @Test
+ public void testSelectAllFromTable() {
+ AdapterContext ctx = new AdapterContext();
+ String sql = "SELECT * FROM TABLENAME";
+ Class elementType = Object[].class;
+ CalcitePrepare.PrepareResult<Object> prepared =
+ new CalcitePrepareImpl().prepareSql(ctx, sql, null, elementType, -1);
+ Object enumerable = prepared.getExecutable();
+ // etc.
+ }
+}
+{% endhighlight %}
+
+### JavaTypeFactory
+
+When Calcite compares types (instances of `RelDataType`), it requires them to be the same
+object. If there are two distinct type instances that refer to the
+same Java type, Calcite may fail to recognize that they match. It is
+recommended to:
+
+* Use a single instance of `JavaTypeFactory` within the calcite context;
+* Store the types so that the same object is always returned for the same type.
+
+## Set up PGP signing keys (for Calcite committers)
+
+Follow instructions [here](http://www.apache.org/dev/release-signing) to
+create a key pair. (On Mac OS X, I did `brew install gpg` and
+`gpg --gen-key`.)
+
+Add your public key to the `KEYS` file by following instructions in
+the `KEYS` file.
+
+## Making a snapshot (for Calcite committers)
+
+Before you start:
+
+* Set up signing keys as described above.
+* Make sure you are using JDK 1.7 (not 1.8).
+* Make sure build and tests succeed with `-Dcalcite.test.db=hsqldb` (the default)
+
+{% highlight bash %}
+# Set passphrase variable without putting it into shell history
+read -s GPG_PASSPHRASE
+
+# Make sure that there are no junk files in the sandbox
+git clean -xn
+mvn clean
+
+mvn -Papache-release -Dgpg.passphrase=${GPG_PASSPHRASE} install
+{% endhighlight %}
+
+When the dry-run has succeeded, change `install` to `deploy`.
+
+## Making a release (for Calcite committers)
+
+Before you start:
+
+* Set up signing keys as described above.
+* Make sure you are using JDK 1.7 (not 1.8).
+* Check that `README`, `README.md` and `doc/howto.md` have the correct version number.
+* Set `version.major` and `version.minor` in `pom.xml`.
+* Make sure build and tests succeed, including with
+ -Dcalcite.test.db={mysql,hsqldb}, -Dcalcite.test.slow=true,
+ -Dcalcite.test.mongodb=true, -Dcalcite.test.splunk=true.
+* Trigger a
+ <a href="https://scan.coverity.com/projects/2966">Coverity scan</a>
+ by merging the latest code into the `julianhyde/coverity_scan` branch,
+ and when it completes, make sure that there are no important issues.
+* Make sure that
+ <a href="https://issues.apache.org/jira/issues/?jql=project%20%3D%20CALCITE%20AND%20status%20%3D%20Resolved%20and%20fixVersion%20is%20null">
+ every "resolved" JIRA case</a> (including duplicates) has
+ a fix version assigned (most likely the version we are
+ just about to release)
+
+Create a release branch named after the release, e.g. `branch-1.1`, and push it to Apache.
+
+{% highlight bash %}
+$ git checkout -b branch-X.Y
+$ git push -u origin branch-X.Y
+{% endhighlight %}
+
+We will use the branch for the entire the release process. Meanwhile,
+we do not allow commits to the master branch. After the release is
+final, we can use `git merge --ff-only` to append the changes on the
+release branch onto the master branch. (Apache does not allow reverts
+to the master branch, which makes it difficult to clean up the kind of
+messy commits that inevitably happen while you are trying to finalize
+a release.)
+
+Now, set up your environment and do a dry run. The dry run will not
+commit any changes back to git and gives you the opportunity to verify
+that the release process will complete as expected.
+
+If any of the steps fail, clean up (see below), fix the problem, and
+start again from the top.
+
+{% highlight bash %}
+# Set passphrase variable without putting it into shell history
+read -s GPG_PASSPHRASE
+
+# Make sure that there are no junk files in the sandbox
+git clean -xn
+mvn clean
+
+# Do a dry run of the release:prepare step, which sets version numbers.
+mvn -DdryRun=true -DskipTests -DreleaseVersion=X.Y.Z-incubating -DdevelopmentVersion=X.Y.Z+1-incubating-SNAPSHOT -Papache-release -Darguments="-Dgpg.passphrase=${GPG_PASSPHRASE}" release:prepare 2>&1 | tee /tmp/prepare-dry.log
+{% endhighlight %}
+
+Check the artifacts:
+
+* In the `target` directory should be these 8 files, among others:
+ * apache-calcite-X.Y.Z-incubating-src.tar.gz
+ * apache-calcite-X.Y.Z-incubating-src.tar.gz.asc
+ * apache-calcite-X.Y.Z-incubating-src.tar.gz.md5
+ * apache-calcite-X.Y.Z-incubating-src.tar.gz.sha1
+ * apache-calcite-X.Y.Z-incubating-src.zip
+ * apache-calcite-X.Y.Z-incubating-src.zip.asc
+ * apache-calcite-X.Y.Z-incubating-src.zip.md5
+ * apache-calcite-X.Y.Z-incubating-src.zip.sha1
+* Note that the file names start `apache-calcite-` and include
+ `incubating` in the version.
+* In the two source distros `.tar.gz` and `.zip` (currently there is
+ no binary distro), check that all files belong to a directory called
+ `apache-calcite-X.Y.Z-incubating-src`.
+* That directory must contain files `DISCLAIMER`, `NOTICE`, `LICENSE`,
+ `README`, `README.md`
+ * Check that the version in `README` is correct
+* In each .jar (for example
+ `core/target/calcite-core-X.Y.Z-incubating.jar` and
+ `mongodb/target/calcite-mongodb-X.Y.Z-incubating-sources.jar`), check
+ that the `META-INF` directory contains `DEPENDENCIES`, `LICENSE`,
+ `NOTICE` and `git.properties`
+* In each .jar, check that `org-apache-calcite-jdbc.properties` is
+ present and does not contain un-substituted `${...}` variables
+* Check PGP, per [this](https://httpd.apache.org/dev/verification.html)
+
+Now, remove the `-DdryRun` flag and run the release for real.
+
+{% highlight bash %}

+
+Apache Calcite is a dynamic data management framework.
+
+It contains many of the pieces that comprise a typical database
+management system, but omits some key functions: storage of data,
+algorithms to process data, and a repository for storing metadata.
+
+Calcite intentionally stays out of the business of storing and
+processing data. As we shall see, this makes it an excellent choice
+for mediating between applications and one or more data storage
+locations and data processing engines. It is also a perfect foundation
+for building a database: just add data.
+
+To illustrate, let's create an empty instance of Calcite and then
+point it at some data.
+
+{% highlight java %}
+public static class HrSchema {
+ public final Employee[] emps = 0;
+ public final Department[] depts = 0;
+}
+Class.forName("org.apache.calcite.jdbc.Driver");
+Properties info = new Properties();
+info.setProperty("lex", "JAVA");
+Connection connection = DriverManager.getConnection("jdbc:calcite:", info);
+CalciteConnection calciteConnection =
+ connection.unwrap(CalciteConnection.class);
+ReflectiveSchema.create(calciteConnection,
+ calciteConnection.getRootSchema(), "hr", new HrSchema());
+Statement statement = calciteConnection.createStatement();
+ResultSet resultSet = statement.executeQuery(
+ "select d.deptno, min(e.empid)\n"
+ + "from hr.emps as e\n"
+ + "join hr.depts as d\n"
+ + " on e.deptno = d.deptno\n"
+ + "group by d.deptno\n"
+ + "having count(*) > 1");
+print(resultSet);
+resultSet.close();
+statement.close();
+connection.close();
+{% endhighlight %}
+
+Where is the database? There is no database. The connection is
+completely empty until `ReflectiveSchema.create` registers a Java
+object as a schema and its collection fields `emps` and `depts` as
+tables.
+
+Calcite does not want to own data; it does not even have favorite data
+format. This example used in-memory data sets, and processed them
+using operators such as `groupBy` and `join` from the linq4j
+library. But Calcite can also process data in other data formats, such
+as JDBC. In the first example, replace
+
+{% highlight java %}
+ReflectiveSchema.create(calciteConnection,
+ calciteConnection.getRootSchema(), "hr", new HrSchema());
+{% endhighlight %}
+
+with
+
+{% highlight java %}
+Class.forName("com.mysql.jdbc.Driver");
+BasicDataSource dataSource = new BasicDataSource();
+dataSource.setUrl("jdbc:mysql://localhost");
+dataSource.setUsername("username");
+dataSource.setPassword("password");
+JdbcSchema.create(calciteConnection.getRootSchema(), "name", dataSource,
+ null, "hr");
+{% endhighlight %}
+
+and Calcite will execute the same query in JDBC. To the application,
+the data and API are the same, but behind the scenes the
+implementation is very different. Calcite uses optimizer rules to push
+the `JOIN` and `GROUP BY` operations to the source database.
+
+In-memory and JDBC are just two familiar examples. Calcite can handle
+any data source and data format. To add a data source, you need to
+write an adapter that tells Calcite what collections in the data
+source it should consider "tables".
+
+For more advanced integration, you can write optimizer
+rules. Optimizer rules allow Calcite to access data of a new format,
+allow you to register new operators (such as a better join algorithm),
+and allow Calcite to optimize how queries are translated to
+operators. Calcite will combine your rules and operators with built-in
+rules and operators, apply cost-based optimization, and generate an
+efficient plan.
+
+### Writing an adapter
+
+The subproject under example/csv provides a CSV adapter, which is
+fully functional for use in applications but is also simple enough to
+serve as a good template if you are writing your own adapter.
+
+See the <a href="tutorial.html">tutorial</a> for information on using
+the CSV adapter and writing other adapters.
+
+See the <a href="howto.html">HOWTO</a> for more information about
+using other adapters, and about using Calcite in general.
+
+## Status
+
+The following features are complete.
+
+* Query parser, validator and optimizer
+* Support for reading models in JSON format
+* Many standard functions and aggregate functions
+* JDBC queries against Linq4j and JDBC back-ends
+* Linq4j front-end
+* SQL features: SELECT, FROM (including JOIN syntax), WHERE, GROUP BY
+ (including GROUPING SETS), aggregate functions (including
+ COUNT(DISTINCT ...) and FILTER), HAVING, ORDER BY (including NULLS
+ FIRST/LAST), set operations (UNION, INTERSECT, MINUS), sub-queries
+ (including correlated sub-queries), windowed aggregates, LIMIT
+ (syntax as <a
+ href="http://www.postgresql.org/docs/8.4/static/sql-select.html#SQL-LIMIT">Postgres</a>);
+ more details in the [SQL reference](reference.html)
+* Local and remote JDBC drivers; see [Avatica](avatica.html)
+* Several [adapters](adapter.html)
+
+
+## Disclaimer
+
+Apache Calcite is an effort undergoing incubation at The Apache Software
+Foundation (ASF), sponsored by the Apache Incubator. Incubation is
+required of all newly accepted projects until a further review
+indicates that the infrastructure, communications, and decision making
+process have stabilized in a manner consistent with other successful
+ASF projects. While incubation status is not necessarily a reflection
+of the completeness or stability of the code, it does indicate that
+the project has yet to be fully endorsed by the ASF.

+A lattice is a framework for creating and populating materialized views,
+and for recognizing that a materialized view can be used to solve a
+particular query.
+
+A lattice represents a star (or snowflake) schema, not a general
+schema. In particular, all relationships must be many-to-one, heading
+from a fact table at the center of the star.
+
+The name derives from the mathematics: a
+<a href="http://en.wikipedia.org/wiki/Lattice_(order)">lattice</a>
+is a
+<a href="http://en.wikipedia.org/wiki/Partially_ordered_set">partially
+ordered set</a> where any two elements have a unique greatest lower
+bound and least upper bound.
+
+[<a href="#ref-hru96">HRU96</a>] observed that the set of possible
+materializations of a data cube forms a lattice, and presented an
+algorithm to choose a good set of materializations. Calcite's
+recommendation algorithm is derived from this.
+
+The lattice definition uses a SQL statement to represent the star. SQL
+is a useful short-hand to represent several tables joined together,
+and assigning aliases to the column names (it more convenient than
+inventing a new language to represent relationships, join conditions
+and cardinalities).
+
+Unlike regular SQL, order is important. If you put A before B in the
+FROM clause, and make a join between A and B, you are saying that
+there is a many-to-one foreign key relationship from A to B. (E.g. in
+the example lattice, the Sales fact table occurs before the Time
+dimension table, and before the Product dimension table. The Product
+dimension table occurs before the ProductClass outer dimension table,
+further down an arm of a snowflake.)
+
+A lattice implies constraints. In the A to B relationship, there is a
+foreign key on A (i.e. every value of A's foreign key has a
+corresponding value in B's key), and a unique key on B (i.e. no key
+value occurs more than once). These constraints are really important,
+because it allows the planner to remove joins to tables whose columns
+are not being used, and know that the query results will not change.
+
+Calcite does not check these constraints. If they are violated,
+Calcite will return wrong results.
+
+A lattice is a big, virtual join view. It is not materialized (it
+would be several times larger than the star schema, because of
+denormalization) and you probably wouldn't want to query it (far too
+many columns). So what is it useful for? As we said above, (a) the
+lattice declares some very useful primary and foreign key constraints,
+(b) it helps the query planner map user queries onto
+filter-join-aggregate materialized views (the most useful kind of
+materialized view for DW queries), (c) gives Calcite a framework
+within which to gather stats about data volumes and user queries, (d)
+allows Calcite to automatically design and populate materialized
+views.
+
+Most star schema models force you to choose whether a column is a
+dimension or a measure. In a lattice, every column is a dimension
+column. (That is, it can become one of the columns in the GROUP BY clause
+to query the star schema at a particular dimensionality). Any column
+can also be used in a measure; you define measures by giving the
+column and an aggregate function.
+
+If "unit_sales" tends to be used much more often as a measure rather
+than a dimension, that's fine. Calcite's algorithm should notice that
+it is rarely aggregated, and not be inclined to create tiles that
+aggregate on it. (By "should" I mean "could and one day will". The
+algorithm does not currently take query history into account when
+designing tiles.)
+
+But someone might want to know whether orders with fewer than 5 items
+were more or less profitable than orders with more than 100. All of a
+sudden, "unit_sales" has become a dimension. If there's virtually zero
+cost to declaring a column a dimension column, I figured let's make
+them all dimension columns.
+
+The model allows for a particular table to be used more than once,
+with a different table alias. You could use this to model say
+OrderDate and ShipDate, with two uses to the Time dimension table.
+
+Most SQL systems require that the column names in a view are unique.
+This is hard to achieve in a lattice, because you often include
+primary and foreign key columns in a join. So Calcite lets you refer
+to columns in two ways. If the column is unique, you can use its name,
+["unit_sales"]. Whether or not it is unique in the lattice, it will be
+unique in its table, so you can use it qualified by its table alias.
+Examples:
+
+* ["sales", "unit_sales"]
+* ["ship_date", "time_id"]
+* ["order_date", "time_id"]
+
+A "tile" is a materialized table in a lattice, with a particular
+dimensionality. (What Kylin calls a "cuboid".) The "tiles" attribute
+of the <a href="model.html#lattice">lattice JSON element</a>
+defines an initial set of tiles to materialize.
+
+If you run the algorithm, you can omit the tiles attribute. Calcite
+will choose an initial set. If you include the tiles attribute, the
+algorithm will start with that list and then start finding other tiles
+that are complementary (i.e. "fill in the gaps" left by the initial
+tiles).

+Calcite models can be represented as JSON files.
+This page describes the structure of those files.
+
+Models can also be built programmatically using the `Schema` SPI.
+
+## Elements
+
+### Root
+
+{% highlight json %}
+{
+ version: '1.0',
+ defaultSchema: 'mongo',
+ schemas: [ Schema... ]
+}
+{% endhighlight %}
+
+`version` (required string) must have value `1.0`.
+
+`defaultSchema` (optional string). If specified, it is
+the name (case-sensitive) of a schema defined in this model, and will
+become the default schema for connections to Calcite that use this model.
+
+`schemas` (optional list of <a href="#schema">Schema</a> elements).
+
+### Schema
+
+Occurs within `root.schemas`.
+
+{% highlight json %}
+{
+ name: 'foodmart',
+ path: ['lib'],
+ cache: true,
+ materializations: [ Materialization... ]
+}
+{% endhighlight %}
+
+`name` (required string) is the name of the schema.
+
+`type` (optional string, default `map`) indicates sub-type. Values are:
+
+* `map` for <a href="#map-schema">Map Schema</a>
+* `custom` for <a href="#custom-schema">Custom Schema</a>
+* `jdbc` for <a href="#jdbc-schema">JDBC Schema</a>
+
+`path` (optional list) is the SQL path that is used to
+resolve functions used in this schema. If specified it must be a list,
+and each element of the list must be either a string or a list of
+strings. For example,
+
+{% highlight json %}
+ path: [ ['usr', 'lib'], 'lib' ]
+{% endhighlight %}
+
+declares a path with two elements: the schema '/usr/lib' and the
+schema '/lib'. Most schemas are at the top level, so you can use a
+string.
+
+`materializations` (optional list of
+<a href="#materialization">Materialization</a>) defines the tables
+in this schema that are materializations of queries.
+
+`cache` (optional boolean, default true) tells Calcite whether to
+cache metadata (tables, functions and sub-schemas) generated
+by this schema.
+
+* If `false`, Calcite will go back to the schema each time it needs
+ metadata, for example, each time it needs a list of tables in order to
+ validate a query against the schema.
+
+* If `true`, Calcite will cache the metadata the first time it reads
+ it. This can lead to better performance, especially if name-matching is
+ case-insensitive.
+
+However, it also leads to the problem of cache staleness.
+A particular schema implementation can override the
+`Schema.contentsHaveChangedSince` method to tell Calcite
+when it should consider its cache to be out of date.
+
+Tables, functions and sub-schemas explicitly created in a schema are
+not affected by this caching mechanism. They always appear in the schema
+immediately, and are never flushed.
+
+### Map Schema
+
+Like base class <a href="#schema">Schema</a>, occurs within `root.schemas`.
+
+{% highlight json %}
+{
+ name: 'foodmart',
+ type: 'map',
+ tables: [ Table... ],
+ functions: [ Function... ]
+}
+{% endhighlight %}
+
+`name`, `type`, `path`, `cache`, `materializations` inherited from
+<a href="#schema">Schema</a>.
+
+`tables` (optional list of <a href="#table">Table</a> elements)
+defines the tables in this schema.
+
+`functions` (optional list of <a href="#function">Function</a> elements)
+defines the functions in this schema.
+
+### Custom Schema
+
+Like base class <a href="#schema">Schema</a>, occurs within `root.schemas`.
+
+{% highlight json %}
+{
+ name: 'mongo',
+ type: 'custom',
+ factory: 'org.apache.calcite.adapter.mongodb.MongoSchemaFactory',
+ operand: {
+ host: 'localhost',
+ database: 'test'
+ }
+}
+{% endhighlight %}
+
+`name`, `type`, `path`, `cache`, `materializations` inherited from
+<a href="#schema">Schema</a>.
+
+`factory` (required string) is the name of the factory class for this
+schema. Must implement interface `org.apache.calcite.schema.SchemaFactory`
+and have a public default constructor.
+
+`operand` (optional map) contains attributes to be passed to the
+factory.
+
+### JDBC Schema
+
+Like base class <a href="#schema">Schema</a>, occurs within `root.schemas`.
+
+{% highlight json %}
+{
+ name: 'foodmart',
+ type: 'jdbc',
+ jdbcDriver: TODO,
+ jdbcUrl: TODO,
+ jdbcUser: TODO,
+ jdbcPassword: TODO,
+ jdbcCatalog: TODO,
+ jdbcSchema: TODO
+}
+{% endhighlight %}
+
+`name`, `type`, `path`, `cache`, `materializations` inherited from
+<a href="#schema">Schema</a>.
+
+`jdbcDriver` (optional string) is the name of the JDBC driver class. It not
+specified, uses whichever class the JDBC DriverManager chooses.
+
+`jdbcUrl` (optional string) is the JDBC connect string, for example
+"jdbc:mysql://localhost/foodmart".
+
+`jdbcUser` (optional string) is the JDBC user name.
+
+`jdbcPassword` (optional string) is the JDBC password.
+
+`jdbcCatalog` (optional string) is the name of the initial catalog in the JDBC
+data source.
+
+`jdbcSchema` (optional string) is the name of the initial schema in the JDBC
+data source.
+
+### Materialization
+
+Occurs within `root.schemas.materializations`.
+
+{% highlight json %}
+{
+ view: 'V',
+ table: 'T',
+ sql: 'select deptno, count(*) as c, sum(sal) as s from emp group by deptno'
+}
+{% endhighlight %}
+
+`view` (optional string) TODO
+
+`table` (optional string) TODO
+
+`sql` (optional string, or list of strings that will be concatenated as a
+ multi-line string) is the SQL definition of the materialization.
+
+### Table
+
+Occurs within `root.schemas.tables`.
+
+{% highlight json %}
+{
+ name: 'sales_fact',
+ columns: [ Column... ]
+}
+{% endhighlight %}
+
+`name` (required string) is the name of this table. Must be unique within the schema.
+
+`type` (optional string, default `custom`) indicates sub-type. Values are:
+
+* `custom` for <a href="#custom-table">Custom Table</a>
+* `view` for <a href="#view">View</a>
+
+`columns` (optional list of <a href="#column">Column</a> elements)
+
+### View
+
+Like base class <a href="#table">Table</a>, occurs within `root.schemas.tables`.
+
+{% highlight json %}
+{
+ name: 'female_emps',
+ type: 'view',
+ sql: "select * from emps where gender = 'F'",
+ modifiable: true
+}
+{% endhighlight %}
+
+`name`, `type`, `columns` inherited from <a href="#table">Table</a>.
+
+`sql` (required string, or list of strings that will be concatenated as a
+ multi-line string) is the SQL definition of the view.
+
+`path` (optional list) is the SQL path to resolve the query. If not
+specified, defaults to the current schema.
+
+`modifiable` (optional boolean) is whether the view is modifiable.
+If null or not specified, Calcite deduces whether the view is modifiable.
+
+A view is modifiable if contains only SELECT, FROM, WHERE (no JOIN, aggregation
+or sub-queries) and every column:
+
+* is specified once in the SELECT clause; or
+* occurs in the WHERE clause with a `column = literal` predicate; or
+* is nullable.
+
+The second clause allows Calcite to automatically provide the correct value for
+hidden columns. It is useful in multi-tenant environments, where the `tenantId`
+column is hidden, mandatory (NOT NULL), and has a constant value for a
+particular view.
+
+Errors regarding modifiable views:
+
+* If a view is marked `modifiable: true` and is not modifiable, Calcite throws
+ an error while reading the schema.
+* If you submit an INSERT, UPDATE or UPSERT command to a non-modifiable view,
+ Calcite throws an error when validating the statement.
+* If a DML statement creates a row that would not appear in the view
+ (for example, a row in `female_emps`, above, with `gender = 'M'`),
+ Calcite throws an error when executing the statement.

+In *merge*, at least one of the WHEN MATCHED and WHEN NOT MATCHED clauses must
+be present.
+
+In *orderItem*, if *expression* is a positive integer *n*, it denotes
+the <em>n</em>th item in the SELECT clause.
+
+An aggregate query is a query that contains a GROUP BY or a HAVING
+clause, or aggregate functions in the SELECT clause. In the SELECT,
+HAVING and ORDER BY clauses of an aggregate query, all expressions
+must be constant within the current group (that is, grouping constants
+as defined by the GROUP BY clause, or constants), or aggregate
+functions, or a combination of constants and aggregate
+functions. Aggregate and grouping functions may only appear in an
+aggregate query, and only in a SELECT, HAVING or ORDER BY clause.
+
+A scalar sub-query is a sub-query used as an expression. It can occur
+in most places where an expression can occur (such as the SELECT
+clause, WHERE clause, or as an argument to an aggregate
+function). If the sub-query returns no rows, the value is NULL; if it
+returns more than one row, it is an error.
+
+A sub-query can occur in the FROM clause of a query and also in IN
+and EXISTS expressions. A sub-query that occurs in IN and
+EXISTS expressions may be correlated; that is, refer to tables in
+the FROM clause of an enclosing query.
+
+## Identifiers
+
+Identifiers are the names of tables, columns and other metadata
+elements used in a SQL query.
+
+Unquoted identifiers, such as emp, must start with a letter and can
+only contain letters, digits, and underscores. They are implicitly
+converted to upper case.
+
+Quoted identifiers, such as `"Employee Name"`, start and end with
+double quotes. They may contain virtually any character, including
+spaces and other punctuation. If you wish to include a double quote
+in an identifier, use another double quote to escape it, like this:
+`"An employee called ""Fred""."`.
+
+In Calcite, matching identifiers to the name of the referenced object is
+case-sensitive. But remember that unquoted identifiers are implicitly
+converted to upper case before matching, and if the object it refers
+to was created using an unquoted identifier for its name, then its
+name will have been converted to upper case also.

+### Aggregate functions
+
+Syntax:
+
+{% highlight SQL %}
+aggregateCall:
+ agg( [ DISTINCT ] value [, value]* ) [ FILTER ( WHERE condition ) ]
+ | agg(*) [ FILTER ( WHERE condition ) ]
+{% endhighlight %}
+
+If `FILTER` is present, the aggregate function only considers rows for which
+*condition* evaluates to TRUE.
+
+If `DISTINCT` is present, duplicate argument values are eliminated before being
+passed to the aggregate function.
+
+| Operator syntax | Description
+|:---------------------------------- |:-----------
+| COUNT( [ DISTINCT ] value [, value]* ) | Returns the number of input rows for which *value* is not null (wholly not null if *value* is composite)
+| COUNT(*) | Returns the number of input rows
+| AVG( [ DISTINCT ] numeric) | Returns the average (arithmetic mean) of *numeric* across all input values
+| SUM( [ DISTINCT ] numeric) | Returns the sum of *numeric* across all input values
+| MAX( [ DISTINCT ] value) | Returns the maximum value of *value* across all input values
+| MIN( [ DISTINCT ] value) | Returns the minimum value of *value* across all input values
+| STDDEV_POP( [ DISTINCT ] numeric) | Returns the population standard deviation of *numeric* across all input values
+| STDDEV_SAMP( [ DISTINCT ] numeric) | Returns the sample standard deviation of *numeric* across all input values
+| VAR_POP( [ DISTINCT ] value) | Returns the population variance (square of the population standard deviation) of *numeric* across all input values
+| VAR_SAMP( [ DISTINCT ] numeric) | Returns the sample variance (square of the sample standard deviation) of *numeric* across all input values
+| COVAR_POP(numeric1, numeric2) | Returns the population covariance of the pair (*numeric1*, *numeric2*) across all input values
+| COVAR_SAMP(numeric1, numeric2) | Returns the sample covariance of the pair (*numeric1*, *numeric2*) across all input values
+| REGR_SXX(numeric1, numeric2) | Returns the sum of squares of the dependent expression in a linear regression model
+| REGR_SYY(numeric1, numeric2) | Returns the sum of squares of the independent expression in a linear regression model
+
+Not implemented:
+
+* REGR_AVGX(numeric1, numeric2)
+* REGR_AVGY(numeric1, numeric2)
+* REGR_COUNT(numeric1, numeric2)
+* REGR_INTERCEPT(numeric1, numeric2)
+* REGR_R2(numeric1, numeric2)
+* REGR_SLOPE(numeric1, numeric2)
+* REGR_SXY(numeric1, numeric2)
+
+### Window functions
+
+| Operator syntax | Description
+|:----------------------------------------- |:-----------
+| COUNT(value [, value ]* ) OVER window | Returns the number of rows in *window* for which *value* is not null (wholly not null if *value* is composite)
+| COUNT(*) OVER window | Returns the number of rows in *window*
+| AVG(numeric) OVER window | Returns the average (arithmetic mean) of *numeric* across all values in *window*
+| SUM(numeric) OVER window | Returns the sum of *numeric* across all values in *window*
+| MAX(value) OVER window | Returns the maximum value of *value* across all values in *window*
+| MIN(value) OVER window | Returns the minimum value of *value* across all values in *window*
+| RANK() OVER window | Returns the rank of the current row with gaps; same as ROW_NUMBER of its first peer
+| DENSE_RANK() OVER window | Returns the rank of the current row without gaps; this function counts peer groups
+| ROW_NUMBER() OVER window | Returns the number of the current row within its partition, counting from 1
+| FIRST_VALUE(value) OVER window | Returns *value* evaluated at the row that is the first row of the window frame
+| LAST_VALUE(value) OVER window | Returns *value* evaluated at the row that is the last row of the window frame
+| LEAD(value, offset, default) OVER window | Returns *value* evaluated at the row that is *offset* rows after the current row within the partition; if there is no such row, instead returns *default*. Both *offset* and *default* are evaluated with respect to the current row. If omitted, *offset* defaults to 1 and *default* to NULL
+| LAG(value, offset, default) OVER window | Returns *value* evaluated at the row that is *offset* rows before the current row within the partition; if there is no such row, instead returns *default*. Both *offset* and *default* are evaluated with respect to the current row. If omitted, *offset* defaults to 1 and *default* to NULL
+| NTILE(value) OVER window | Returns an integer ranging from 1 to *value*, dividing the partition as equally as possible
+
+Not implemented:
+
+* COUNT(DISTINCT value) OVER window
+* FIRST_VALUE(value) IGNORE NULLS OVER window
+* LAST_VALUE(value) IGNORE NULLS OVER window
+* PERCENT_RANK(value) OVER window
+* CUME_DIST(value) OVER window
+* NTH_VALUE(value, nth) OVER window
+
+### Grouping functions
+
+| Operator syntax | Description
+|:-------------------- |:-----------
+| GROUPING(expression) | Returns 1 if expression is rolled up in the current row's grouping set, 0 otherwise
+| GROUP_ID() | Returns an integer that uniquely identifies the combination of grouping keys
+| GROUPING_ID(expression [, expression ] * ) | Returns a bit vector of the given grouping expressions
