+ <title>Drill 1.8 Released</title>
+ <description><p>Today, we&#39;re happy to announce the availability of Drill 1.8.0. You can download it <a href="https://drill.apache.org/download/">here</a>.</p>
+
+<p>The release provides the following bug fixes and improvements:</p>
+
+<h2 id="metadata-cache-pruning">Metadata Cache Pruning</h2>
+
+<p>Drill now applies partition pruning to the metadata cache file. See <a href="https://drill.apache.org/docs/partition-pruning-introduction/">Partition Pruning Introduction</a> and <a href="https://drill.apache.org/docs/optimizing-parquet-metadata-reading/">Optimizing Parquet Metadata Reading</a>. </p>
+
+<h2 id="if-exists-support">IF EXISTS Support</h2>
+
+<p>You can include the new IF EXISTS parameter with the DROP TABLE and DROP VIEW commands to prevent Drill from returning error messages when a table or view does not exist. See <a href="https://drill.apache.org/docs/drop-table/">DROP TABLE</a> and <a href="https://drill.apache.org/docs/drop-view/">DROP VIEW</a>.</p>
+
+<h2 id="describe-schema-command">DESCRIBE SCHEMA Command</h2>
+
+<p>Drill now supports the DESCRIBE SCHEMA command which provides schema properties for storage plugin configurations and workspaces. See <a href="https://drill.apache.org/docs/describe/">DESCRIBE</a>. </p>
+
+<h2 id="multi-byte-delimiter-support">Multi-Byte Delimiter Support</h2>
+
+<p>Drill now supports multi-byte delimiters for text files, such as \r\n. See <a href="https://drill.apache.org/docs/plugin-configuration-basics/#list-of-attributes-and-definitions">List of Attributes and Definitions</a>. </p>
+
+<h2 id="filter-selectivity-estimate-parameters">Filter Selectivity Estimate Parameters</h2>
+
+<p>New parameters set the minimum filter selectivity estimate to increase the parallelization of the major fragment performing a join. See <a href="https://drill.apache.org/docs/configuration-options-introduction/#system-options">System Options</a>. </p>
+
+<p>A complete list of JIRAs resolved in the 1.8.0 release can be found <a href="https://issues.apache.org/jira/secure/ReleaseNote.jspa?version=12334768&amp;styleName=Html&amp;projectId=12313820&amp;Create=Create&amp;atl_token=A5KQ-2QAV-T4JA-FDED%7Ce8d020149d9a6082481af301e563adbe35c76a87%7Clout">here</a>.</p>

- <title>Drill 1.0 Released</title>
- <description><p>We embarked on the Drill project in late 2012 with two primary objectives:</p>
-
-<ul>
-<li>Enable agility by getting rid of all the traditional overhead - namely, the need to load data, create and maintain schemas, transform data, etc. We wanted to develop a system that would support the speed and agility at which modern organizations want (or need) to operate in this era.</li>
-<li>Unlock the data housed in non-relational datastores like NoSQL, Hadoop and cloud storage, making it available not only to developers, but also business users, analysts, data scientists and anyone else who can write a SQL query or use a BI tool. Non-relational datastores are capturing an increasing share of the world&#39;s data, and it&#39;s incredibly hard to explore and analyze this data.</li>
-</ul>
-
-<p>Today we&#39;re happy to announce the availability of the production-ready Drill 1.0 release. This release addresses <a href="https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12313820&amp;version=12325568">228 JIRAs</a> on top of the 0.9 release earlier this month. Highlights include:</p>
-
-<ul>
-<li>Substantial improvements in stability, memory handling and performance</li>
-<li>Improvements in Drill CLI experience with addition of convenience shortcuts and improved colors/alignment</li>
-<li>Substantial additions to documentation including coverage of troubleshooting, performance tuning and many additions to the SQL reference</li>
-<li>Enhancements in join planning to facilitate high speed planning of large and complicated joins</li>
-<li>Add support for new context functions including <code>CURRENT_USER</code> and <code>CURRENT_SCHEMA</code></li>
-<li>Ability to treat all numbers as approximate decimals when reading JSON</li>
-<li>Enhancements in Drill&#39;s text and CSV handling to support first row skipping, configurable field/line delimiters and configurable quoting</li>
-<li>Improved JDBC compatibility (and tracing proxy for easy debugging).</li>
-<li>Ability to do JDBC connections with direct urls (avoiding ZooKeeper)</li>
-<li>Automatic selection of spooling or back-pressure exchange semantics to avoid distributed deadlocks in complex sort-heavy queries</li>
-<li>Improvements in query profile reporting</li>
-<li>Addition of <code>ILIKE(VARCHAR, PATTERN)</code> and <code>SUBSTR(VARCHAR, REGEX)</code> functions</li>
-</ul>
-
-<p>We would not have been able to reach this milestone without the tremendous effort by all the <a href="/team/">committers</a> and contributors, and we would like to congratulate the entire community on achieving this milestone. While 1.0 is an exciting milestone, it&#39;s really just the beginning of the journey. We&#39;ll release 1.1 next month, and continue with our 4-6 week release cycle, so you can count on many additional enhancements over the coming months.</p>

+ <p>Today, we're happy to announce the availability of Drill 1.8.0. You can download it <a href="https://drill.apache.org/download/">here</a>.</p>
+
+<p>The release provides the following bug fixes and improvements:</p>
+
+<h2 id="metadata-cache-pruning">Metadata Cache Pruning</h2>
+
+<p>Drill now applies partition pruning to the metadata cache file. See <a href="https://drill.apache.org/docs/partition-pruning-introduction/">Partition Pruning Introduction</a> and <a href="https://drill.apache.org/docs/optimizing-parquet-metadata-reading/">Optimizing Parquet Metadata Reading</a>. </p>
+
+<h2 id="if-exists-support">IF EXISTS Support</h2>
+
+<p>You can include the new IF EXISTS parameter with the DROP TABLE and DROP VIEW commands to prevent Drill from returning error messages when a table or view does not exist. See <a href="https://drill.apache.org/docs/drop-table/">DROP TABLE</a> and <a href="https://drill.apache.org/docs/drop-view/">DROP VIEW</a>.</p>
+
+<h2 id="describe-schema-command">DESCRIBE SCHEMA Command</h2>
+
+<p>Drill now supports the DESCRIBE SCHEMA command which provides schema properties for storage plugin configurations and workspaces. See <a href="https://drill.apache.org/docs/describe/">DESCRIBE</a>. </p>
+
+<h2 id="multi-byte-delimiter-support">Multi-Byte Delimiter Support</h2>
+
+<p>Drill now supports multi-byte delimiters for text files, such as \r\n. See <a href="https://drill.apache.org/docs/plugin-configuration-basics/#list-of-attributes-and-definitions">List of Attributes and Definitions</a>. </p>
+
+<h2 id="filter-selectivity-estimate-parameters">Filter Selectivity Estimate Parameters</h2>
+
+<p>New parameters set the minimum filter selectivity estimate to increase the parallelization of the major fragment performing a join. See <a href="https://drill.apache.org/docs/configuration-options-introduction/#system-options">System Options</a>. </p>
+
+<p>A complete list of JIRAs resolved in the 1.8.0 release can be found <a href="https://issues.apache.org/jira/secure/ReleaseNote.jspa?version=12334768&styleName=Html&projectId=12313820&Create=Create&atl_token=A5KQ-2QAV-T4JA-FDED%7Ce8d020149d9a6082481af301e563adbe35c76a87%7Clout">here</a>.</p>

+ <p><strong>Release date:</strong> August 30, 2016</p>
+
+<p>Today, we're happy to announce the availability of Drill 1.8.0. You can download it <a href="https://drill.apache.org/download/">here</a>.</p>
+
+<h2 id="new-features">New Features</h2>
+
+<p>This release of Drill provides the following new features: </p>
+
+<ul>
+<li>Metadata cache pruning</li>
+<li>IF EXISTS parameter with the DROP TABLE and DROP VIEW commands</li>
+<li>DESCRIBE SCHEMA command</li>
+<li>Multi-byte delimiter support</li>
+<li>New parameters for filter selectivity estimates<br></li>
+</ul>
+
+<h2 id="configuration-and-launch-script-changes">Configuration and Launch Script Changes</h2>
+
+<p>This release of Drill also includes the following changes to the configuration and launch scripts: </p>
+
+<ul>
+<li>The <code>$DRILL_HOME/conf/drill-env.sh</code> file has been simplified. Default Drill settings have moved out of this file and now reside in <code>$DRILL_HOME/bin/drill-config.sh</code>. The <code>drill-env.sh</code> file now ships with descriptions of the options that you can set. You can override many settings by creating an entry in <code>$DRILL_HOME/conf/drill-env.sh</code>. (<a href="https://issues.apache.org/jira/browse/DRILL-4581">DRILL-4581</a>)<br></li>
+<li>Due to issues at high concurrency, the native Linux epoll transport is now disabled by default. (<a href="https://issues.apache.org/jira/browse/DRILL-4623">DRILL-4623</a>)<br></li>
+</ul>
+
+<p>Changes to the Drill launch scripts provide a new option that simplifies the Drill upgrade for Drill 1.8 and later. The new scripts support a \u201csite directory\u201d that holds site-specific files separate from the Drill product directory. The site directory is a simple extension of the config directory in previous Drill releases. You can add a \u201cjars\u201d subdirectory to the config directory for your custom jars instead of storing them in $DRILL_HOME. You can even add native libraries in the new \u201clib\u201d directory and Drill automatically loads them. </p>
+
+<p>Example: </p>
+<div class="highlight"><pre><code class="language-text" data-lang="text"> /my/conf/dir
+ |- drill-override.conf
+ |- drill-env.sh
+ |- jars
+ |- myudf.jar
+ |- lib
+ |- mysecurity.so
+</code></pre></div>
+<p>To use the site directory:</p>
+<div class="highlight"><pre><code class="language-text" data-lang="text"> drillbit.sh \u2014site /my/conf/dir start
+</code></pre></div>
+<p>Note that <code>--config</code> still works as well.</p>
+
+<p>You can set an environment variable for the directory:</p>
+<div class="highlight"><pre><code class="language-text" data-lang="text"> export DRILL_CONF_DIR=/my/conf/dir
+ drillbit.sh start
+</code></pre></div>
+<p>The site directory works with <code>drillbit.sh</code> and the various Drill client scripts.</p>
+
+<p>To upgrade Drill using the new site directory, just delete the old Drill product directory and expand the Drill archive to create a new one. There is no need to back up and merge files each time you upgrade because the site files are not affected by an upgrade. Using the site directory, you can have different site directories for different Drill sessions: one for development, another for test, and so on. You can use the site directory to run multiple Drill clusters from as single Drill installation by creating a site directory for each Drill cluster and then configuring Drill. </p>

+ <p>The DROP VIEW command removes a view that was created in a workspace using the CREATE VIEW command. As of Drill 1.8, you can include the IF EXISTS parameter with the DROP VIEW command.</p>
<h2 id="syntax">Syntax</h2>
<p>The DROP VIEW command supports the following syntax:</p>
-<div class="highlight"><pre><code class="language-text" data-lang="text"> DROP VIEW [workspace.]view_name;
+<div class="highlight"><pre><code class="language-text" data-lang="text">DROP VIEW [IF EXISTS] [workspace.]view_name;
</code></pre></div>
+<h2 id="parameters">Parameters</h2>
+
+<p>IF EXISTS<br>
+Drill does not throw an error if the view does not exist. Instead, Drill returns "<code>View [view_name] not found in schema [workspace].</code>" </p>
+
+<p><em>workspace</em><br>
+The location of the view in subdirectories of a local or distributed file system.</p>
+
+<p><em>name</em><br>
+A unique directory or file name, optionally prefaced by a storage plugin name, such as <code>dfs</code>, and a workspace, such as <code>tmp</code> using dot notation. </p>
+
<h2 id="usage-notes">Usage Notes</h2>
<p>When you drop a view, all information about the view is deleted from the workspace in which it was created. DROP VIEW applies to the view only, not to the underlying data sources used to create the view. However, if you drop a view that another view is dependent on, you can no longer use the dependent view. If the underlying tables or views change after a view is created, you may want to drop and re-create the view. Alternatively, you can use the CREATE OR REPLACE VIEW syntax to update the view.</p>
<h2 id="example">Example</h2>
-<p>This example shows you some steps to follow when you want to drop a view in Drill using the DROP VIEW command. A workspace named \u201cdonuts\u201d was created for the steps in this example.
-Complete the following steps to drop a view in Drill:

<li>Move the downloaded file to the directory where you want to install Drill.</li>
<li>Unzip the GZ file using a third-party tool. If the tool you use does not unzip the underlying TAR file as well as the GZ file, perform a second unzip to extract the Drill software. The extraction process creates the installation directory containing the Drill software. </li>

<p>Partition pruning is a performance optimization that limits the number of files and partitions that Drill reads when querying file systems and Hive tables. When you partition data, Drill only reads a subset of the files that reside in a file system or a subset of the partitions in a Hive table when a query matches certain filter criteria.</p>
+<p>As of Drill 1.8, partition pruning also applies to the Parquet metadata cache. When data is partitioned in a directory hierarchy, Drill attempts to read the metadata cache file from a sub-partition, based on matching filter criteria instead of reading from the top level partition, to reduce the amount of metadata read during the query planning time. If you created a metadata cache file in a previous version of Drill, you must issue the REFRESH TABLE METADATA command to regenerate the metadata cache file before running queries for metadata cache pruning to occur. See <a href="/docs/optimizing-parquet-metadata-reading/">Optimizing Parquet Metadata Reading</a> for more information. </p>
+
<p>The query planner in Drill performs partition pruning by evaluating the filters. If no partition filters are present, the underlying Scan operator reads all files in all directories and then sends the data to operators, such as Filter, downstream. When partition filters are present, the query planner pushes the filters down to the Scan if possible. The Scan reads only the directories that match the partition filters, thus reducing disk I/O.</p>

This option is useful for deeply nested queries with complicated predicates and serves as a workaround when statistics are insufficient or unavailable. The selectivity can vary between 0 and 1. The value of this option caps the estimated SELECTIVITY. The estimated ROWCOUNT is derived by multiplying the estimated SELECTIVITY by the estimated ROWCOUNT of the upstream operator. The estimated ROWCOUNT displays when you use the EXPLAIN PLAN INCLUDING ALL ATTRIBUTES FOR command. This option does not control the estimated ROWCOUNT of downstream operators (post FILTER). However, estimated ROWCOUNTs may change because the operator ROWCOUNTs depend on their downstream operators. The FILTER operator relies on the input of its immediate upstream operator, for example SCAN, AGGREGATE. If two filters are present in a plan, e
ach filter may have a different estimated ROWCOUNT based on the immediate upstream operator's estimated ROWCOUNT.</td>
