# Multilingual
-Multilingual support was added to the website in June 2021 using the polyglot Jekyll plugin. The fallback language is set to English which means that when a translated page is not available the English version will be shown. This means that a language which is incompletely translated is still deployable with no adverse effects.
+Multilingual support was added to the docs section of the website in June 2021 using the polyglot Jekyll plugin. The fallback language is set to English which means that when a translated page is not available the English version will be shown.
## Add a new language
-1. Add the two-letter language code (`lang-code` forthwith) to the `languages` property in _config.yml.
-2. Add a `lang-code/` subdirectory to the root directory.
-3. Add a `lang-code/` subdirectory to each collection that will be translated, e.g. `_docs/lang-code/`.
-4. Check the `exclude_from_localization` list in _config.yml to ensure that the content you
-want to translate is not excluded from processing by the multlingual plugin.
+1. Add the two-letter language code to the `languages` property in _config.yml.
+2. Add a subdirectory with name equal to the language code under _docs/.
-## Add translated site pages
+## Add translated documentation
-The English versions of "site" pages such as index.html are stored in the root directory. Create corresponding translated pages under `lang-code/` in which you set `lang` in the front matter to `lang-code` and leave the `permalink` the same as the English page.
-
-## Add translated collection pages
-
-The English versions of "collection" pages such as the markdown under _docs/ are stored in an en/ subdirectory of the collection root. Create corresponding translated pages in the collection under `lang-code/` in which you translate both `title` and `parent` in the front matter but leave the `slug` the same as the English page and set `lang` to `lang-code`.
+1. Incrementally add translated pages to the relevant language subdirectory under _docs/ by replicating the path structure under _docs/en.
+2. In the "front matter" at the top of each new page, translate both `title` and `parent` but leave the `slug` the same as the English page and set `lang` to the language code you are writing in.
+3. A language which is incompletely translated is still deployable with no adverse effects (see the remark concerning English fallback above).

+## Aggregate Functions
+
+The following table lists the aggregate functions that you can use in Drill
+queries.
+
+|\-------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------|
+
+| **Function** | **Argument Type** | **Return Type** |
+| ------------------------------------------------------------ | ----------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------ |
+| ANY_VALUE(expression) | BIT, INT, BIGINT, FLOAT4, FLOAT8, DATE, TIMESTAMP, TIME, VARCHAR, VARBINARY, LIST, MAP, INTERVAL, INTERVALDAY, INTERVALYEAR, VARDECIMAL | Same as argument type |
+| AVG(expression) | SMALLINT, INTEGER, BIGINT, FLOAT, DOUBLE, DECIMAL, INTERVAL | DECIMAL for DECIMAL argument, DOUBLE for all other arguments |
+| BOOL_AND(expression), BOOL_OR(expression) | BIT | BIT |
+| BIT_AND(expression), BIT_OR(expression), BIT_XOR(expression) | INT, BIGINT | Same as argument type |
+| COUNT(\*) | - | BIGINT |
+| COUNT(\[DISTINCT\] expression) | any | BIGINT |
+| MAX(expression), MIN(expression) | BINARY, DECIMAL, VARCHAR, DATE, TIME, or TIMESTAMP | Same as argument type |
+| SUM(expression) | SMALLINT, INTEGER, BIGINT, FLOAT, DOUBLE, DECIMAL, INTERVAL | DECIMAL for DECIMAL argument, BIGINT for any integer-type argument (including BIGINT), DOUBLE for floating-point arguments |
+| ------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------ |
+
+- Drill 1.14 and later supports the ANY_VALUE function.
+- Starting in Drill 1.14, the DECIMAL data type is enabled by default.
+- AVG, COUNT, MIN, MAX, and SUM accept ALL and DISTINCT keywords. The default is
+ ALL.
+- The aggregate function examples use the `cp` storage plugin to access the
+ [`employee.json`](%7B%7Bsite.baseurl%7D%7D/docs/querying-json-files/) file
+ installed with Drill. By default, JSON reads numbers as double-precision
+ floating point numbers. These examples assume that you are using the default
+ option
+ [all_text_mode](%7B%7Bsite.baseurl%7D%7D/docs/json-data-model/#handling-type-differences)
+ set to false.
+
+## ANY_VALUE
+
+Supported in Drill 1.14 and later. Returns one of the values of value across all
+input values. This function is NOT specified in the SQL standard.
+
+### ANY_VALUE Syntax
+
+```
+ANY_VALUE([ ALL | DISTINCT ] value)
+```
+
+### ANY_VALUE Examples
+
+```

+
+## Aggregate Statistical Functions
+
+The following table lists the aggregate statistical functions that you can use
+in Drill queries.
+
+| **Function** | **Argument Type** | **Return Type** |
+| ----------------------------- | ------------------------------------------------- | ----------------------------------------------- |
+| APPROX_COUNT_DUPS(expression) | any | BIGINT |
+| STDDEV(expression) | SMALLINT, INTEGER, BIGINT, FLOAT, DOUBLE, DECIMAL | DECIMAL for DECIMAL arguments, otherwise DOUBLE |
+| STDDEV_POP(expression) | SMALLINT, INTEGER, BIGINT, FLOAT, DOUBLE, DECIMAL | DECIMAL for DECIMAL arguments, otherwise DOUBLE |
+| VARIANCE(expression) | SMALLINT, INTEGER, BIGINT, FLOAT, DOUBLE, DECIMAL | DECIMAL for DECIMAL arguments, otherwise DOUBLE |
+| VAR_POP(expression) | SMALLINT, INTEGER, BIGINT, FLOAT, DOUBLE, DECIMAL | DECIMAL for DECIMAL arguments, otherwise DOUBLE |
+
+## APPROX_COUNT_DUPS
+
+Returns an approximate count of the values that are duplicates (not unique).
+
+### APPROX_COUNT_DUPS Syntax
+
+```
+APPROX_COUNT_DUPS( expression )
+```
+
+### APPROX_COUNT_DUPS Examples
+
+```
+select
+ COUNT(*),
+ APPROX_COUNT_DUPS(e1.employee_id),
+ APPROX_COUNT_DUPS(e1.gender)
+FROM cp.`employee.json` e1
+
+|--------|--------|--------|
+| EXPR$0 | EXPR$1 | EXPR$2 |
+| ------ | ------ | ------ |
+| 1155 | 0 | 1153 |
+|--------|--------|--------|
+```
+
+Use COUNT - APPROX_COUNT_DUPS to approximate a distinct count.
+
+```
+select
+ COUNT(*),
+ COUNT(salary) - APPROX_COUNT_DUPS(salary),
+ COUNT(distinct salary)
+from cp.`employee.json`;
+
+|--------|--------|--------|
+| EXPR$0 | EXPR$1 | EXPR$2 |
+|--------|--------|--------|
+| 1155 | 48 | 48 |
+|--------|--------|--------|
+```
+
+### APPROX_COUNT_DUPS Usage Notes
+
+The underlying Bloom filter is a probabilistic data structure that may return a
+false positive when an element is tested for duplication. Consequently, the
+approximate count returned _overestimates_ the true duplicate count. In return
+for this inaccuracy, Bloom filters are highly space- and time-efficient at large
+scales with the specifics determined by the parameters of the filter (see
+below).
+
+### Configuration options
+
+{% include startnote.html %} The APPROX_COUNT_DUPS function is used internally
+by Drill when it computes table statistics. As a result, setting configuration
+options that affect it in the global configuration scope will affect the
+computation of table statistics accordingly. {% include endnote.html %}
+
+- exec.statistics.ndv_extrapolation_bf_elements
+- exec.statistics.ndv_extrapolation_bf_fpprobability
+
+## STDDEV

+
+|-------------------|
+| EXPR$0 |
+|-------------------|
+| 5371.847873988941 |
+|-------------------|
+```
+
+### STDDEV Usage Notes
+
+1. Aliases: STDDEV_SAMP
+
+## STDDEV_POP
+
+Returns the estimate of the population standard deviation obtained by applying
+Bessel's correction to the sample standard deviation.
+

-false positive when an element is tested for duplication. Consequently, the
-approximate count returned <em>overestimates</em> the true duplicate count. In return

# Multilingual
-Multilingual support was added to the website in June 2021 using the polyglot Jekyll plugin. The fallback language is set to English which means that when a translated page is not available the English version will be shown. This means that a language which is incompletely translated is still deployable with no adverse effects.
+Multilingual support was added to the docs section of the website in June 2021 using the polyglot Jekyll plugin. The fallback language is set to English which means that when a translated page is not available the English version will be shown.
## Add a new language
-1. Add the two-letter language code (`lang-code` forthwith) to the `languages` property in _config.yml.
-2. Add a `lang-code/` subdirectory to the root directory.
-3. Add a `lang-code/` subdirectory to each collection that will be translated, e.g. `_docs/lang-code/`.
-4. Check the `exclude_from_localization` list in _config.yml to ensure that the content you
-want to translate is not excluded from processing by the multlingual plugin.
+1. Add the two-letter language code to the `languages` property in _config.yml.
+2. Add a subdirectory with name equal to the language code under _docs/.
-## Add translated site pages
+## Add translated documentation
-The English versions of "site" pages such as index.html are stored in the root directory. Create corresponding translated pages under `lang-code/` in which you set `lang` in the front matter to `lang-code` and leave the `permalink` the same as the English page.
-
-## Add translated collection pages
-
-The English versions of "collection" pages such as the markdown under _docs/ are stored in an en/ subdirectory of the collection root. Create corresponding translated pages in the collection under `lang-code/` in which you translate both `title` and `parent` in the front matter but leave the `slug` the same as the English page and set `lang` to `lang-code`.
+1. Incrementally add translated pages to the relevant language subdirectory under _docs/ by replicating the path structure under _docs/en.
+2. In the "front matter" at the top of each new page, translate both `title` and `parent` but leave the `slug` the same as the English page and set `lang` to the language code you are writing in.
+3. A language which is incompletely translated is still deployable with no adverse effects (see the remark concerning English fallback above).

- <p>One of the many interesting and unique features about Drill is its ability to support multiple query languages, data formats, and data sources, as well as cross-platform querying (such as joining HBase tables with your Mongo collections) using ANSI SQL.</p>
-
-<p>As of now, Drill supports multiple storage plugins, including HDFS, HBase, Hive, and LocalFileSystem. Since Drill is optimized for nested data, we realized that a Mongo storage plugin would be a useful feature.</p>
-
-<p>So, recently Kamesh and I (we have an avid interest in all things Mongo) contributed the MongoDB storage plugin feature to the Apache Drill project. As part of this blog post, we would like to provide instructions on how to use this plugin, which has been included in the <a href="http://incubator.apache.org/drill/download/">Drill 0.6 release</a>.</p>
-
-<p>The instructions are divided into the following subtopics:</p>
-
-<ul>
- <li>Drill and Mongo setup (standalone/replicated/sharded)</li>
- <li>Running queries</li>
- <li>Securely accessing MongoDB</li>
- <li>Optimizations</li>
-</ul>

-<p><img src="/static/sql-on-mongodb/sharded.png" alt="Drill on MongoDB in sharded mode" /></p>
-
-<p>In sharded mode, drillbit first connects to the <code class="language-plaintext highlighter-rouge">mongos</code> server to get the shard information.</p>
-
-<h2 id="endpoint-assignments">Endpoint Assignments</h2>
-
-<p>Drill is designed to maximize data locality:</p>
-
-<ul>
- <li>When drillbits and shards run together on the same machines, each drillbit (endpoint) will read the chunks from the local shard. That is, all the chunks from a shard will be assigned to its local drillbit. This is known as data locality, and is the ideal scenario.</li>
- <li>When all drillbits and shards are running on different machines, chunks will be assigned to drillbits in a round-robin fashion. In this case there is no data locality.</li>
- <li>When some of drillbits and shards are colocated, and some of them are running on different machines, partial data locality is achieved.</li>
-</ul>
-
-<h2 id="running-queries">Running Queries</h2>
-
-<p>Here is a simple exercise that provides steps for creating an <code class="language-plaintext highlighter-rouge">empinfo</code> collection in an <code class="language-plaintext highlighter-rouge">employee</code> database in Mongo that you can query using Drill:</p>
-
-<ol>
- <li>Download <a href="http://media.mongodb.org/zips.json">zips.json</a> and the <a href="/static/sql-on-mongodb/empinfo.json">empinfo.json</a> dataset referenced at the end of blog.</li>
- <li>
- <p>Import the zips.json and empinfo.json files into Mongo using the following command:</p>
-
- <div class="language-bash highlighter-rouge"><div class="highlight"><pre class="highlight"><code> mongoimport <span class="nt">--host</span> localhost <span class="nt">--db</span> <span class="nb">test</span> <span class="nt">--collection</span> zips < zips.json
- mongoimport <span class="nt">--host</span> localhost <span class="nt">--db</span> employee <span class="nt">--collection</span> empinfo < empinfo.json
-</code></pre></div> </div>
- </li>
- <li>Issue the following queries either from sqlline (Drill’s shell) or from the Drill Web UI to get corresponding results from the Mongo collection.
- <ul>
- <li>To issue queries from the web UI, open the Drill web UI and go to Query tab.</li>
- <li>
- <p>To issue queries from sqlline, connect to sqlline using the following command:</p>
-
- <div class="language-bash highlighter-rouge"><div class="highlight"><pre class="highlight"><code> <DRILLHOME>/bin/sqlline <span class="nt">-u</span> jdbc:drill:zk<span class="o">=</span>zkhost:2181 <span class="nt">-n</span> admin <span class="nt">-p</span> admin

-
-<p><em>Note</em>: If a field contains a mixture of different data types across different records, such as both int and decimal values, then queries fail unless <code class="language-plaintext highlighter-rouge">store.mongo.all_text_mode = true</code> and aggregations fail in that case.

-
-<p>To set <code class="language-plaintext highlighter-rouge">store.mongo.all_text_mode = true</code>, execute the following command in sqlline:</p>
-
-<div class="language-sql highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="k">alter</span> <span class="k">session</span> <span class="k">set</span> <span class="n">store</span><span class="p">.</span><span class="n">mongo</span><span class="p">.</span><span class="n">all_text_mode</span> <span class="o">=</span> <span class="k">true</span>

-
-<h2 id="securely-accessing-mongodb">Securely Accessing MongoDB</h2>
-<p>Create two databases, emp and zips. For each database, create a user with read privileges. As an example, for the zips database, create a user “apache” with read privileges. For the emp database, create a user “drill” with read privileges.</p>
-
-<p>The apache user will be able to query the zips database by using the following storage plugin configuration:</p>

- <p>The Apache Software Foundation has just announced that it has promoted Drill to a top-level project at Apache, similar to other well-known projects like Apache Hadoop and httpd (the world’s most popular Web server). This marks a significant accomplishment for the Drill community, and I wanted to personally thank everyone who has contributed to the project. It takes many people, and countless hours, to develop something as complex and innovative as Drill.</p>
-
-<p>In this post I wanted to reflect on the past and future of Drill.</p>
-
-<h2 id="why-we-started-drill">Why We Started Drill</h2>
-
-<h3 id="the-evolution-of-application-development-and-data">The Evolution of Application Development and Data</h3>
-
-<p>Over the last decade, organizations have been striving to become more agile and data-driven, seeking to gain competitive advantage in their markets. This trend has led to dramatic changes in the way applications are built and delivered, and in the type and volume of data that is being leveraged.</p>
-
-<p><strong>Applications</strong>: In previous decades, software development was a carefully orchestrated and planned process. The release cycles were often measured in years, and upgrades were infrequent. Today, Web and mobile applications are developed in a much more iterative fashion. The release cycles are measured in days or weeks, and upgrades are a non-issue. (What version of Salesforce.com or Google Maps are you using?)</p>
-
-<p><strong>Data</strong>: In previous decades, data was measured in MBs or GBs, and it was highly structured and denormalized. Today’s data is often measured in TBs or PBs, and it tends to be multi-structured — a combination of unstructured, semi-structured and structured. The data comes from many different sources, including a variety of applications, devices and services, and its structure changes much more frequently.</p>
-
-<h3 id="a-new-generation-of-datastores">A New Generation of Datastores</h3>
-
-<p>The relational database, which was invented in 1970, was not designed for these new processes and data volumes and structures. As a result, a new generation of datastores has emerged, including HDFS, NoSQL (HBase, MongoDB, etc.) and search (Elasticsearch, Solr). These systems are schema-free (also known as “dynamic schema”). Applications, as opposed to DBAs, control the data structure, enabling more agility and flexibility. For example, an application developer can independently evol [...]
-
-<h2 id="the-need-for-a-new-query-engine">The Need for a New Query Engine</h2>
-
-<p>With data increasingly being stored in schema-free datastores (HDFS, HBase, MongoDB, etc.) and a variety of cloud services, users need a way to explore and analyze this data, and a way to visualize it with BI tools (reports, dashboards, etc.). In 2012 we decided to embark on a journey to create the world’s next-generation SQL engine. We had several high-level requirements in mind:</p>
-
-<ul>
- <li><strong>A schema-free data model.</strong> Schema-free datastores (HDFS, NoSQL, search) need a schema-free SQL engine. These datastores became popular for a reason, and we shouldn’t expect organizations to sacrifice those advantages in order to enjoy SQL-based analytics and BI. Today’s organizations need agility and flexibility to cope with the volume, variety and velocity associated with modern applications and data.</li>
- <li><strong>A standalone query engine that supports multiple data sources.</strong> Most companies now use a variety of best-of-breed datastores and services to store data. This is true not just for large Global 2000 companies, but also for small startups. For example, it is not uncommon for a startup to have data in MySQL, MongoDB, HBase and HDFS, as well as a variety of online services. ETL was hard even 10 years ago when data was static and 100x smaller than it is today, and in toda [...]
- <li><strong>Ease of use.</strong> The SQL engine can’t be hard to setup and use. Analysts and developers should be able to download and use it without deploying any complex infrastructure such as Hadoop.</li>
- <li><strong>Scalability and performance.</strong> The SQL engine must support interactive queries. It can’t be batch-oriented like Hive. In addition, it must be able to scale linearly from a small laptop or virtual machine to a large cluster with hundreds or thousands of powerful servers.</li>
-</ul>
-
-<p>With these requirements in mind, we decided to incubate a new project in 2012 in the Apache Software Foundation so that a community of vendors and developers could come together and develop the technology. (One little known fact is that the name “Drill” was actually suggested by Google engineers due to its inspiration from Google’s Dremel execution engine.)</p>
-
-<p>After almost two years of research and development, we released Drill 0.4 in August, and continued with monthly releases since then.</p>
-
-<h2 id="whats-next">What’s Next</h2>
-
-<p>Graduating to a top-level project is a significant milestone, but it’s really just the beginning of the journey. In fact, we’re currently wrapping up Drill 0.7, which includes hundreds of fixes and enhancements, and we expect to release that in the next couple weeks.</p>
-
-<p>Drill is currently being used by dozens of organizations, ranging from small startups to some of the largest Fortune 100s. These organizations are already gaining tremendous business value with Drill. As we march towards a 1.0 release early next year, these organizations are helping us shape the project and ensure that it meets the needs of a broad range of organizations as well as users (business analysts, technical analysts, data scientists and application developers). I would like [...]

-<p>Happy Drilling!<br />
