# Multilingual
-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.
+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.
## Add a new language
-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/.
+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.
-## Add translated documentation
+## Add translated site pages
-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).
+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`.

-- 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.
-

-## 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

-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.
+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.
## Add a new language
-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/.
+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.
-## Add translated documentation
+## Add translated site pages
-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).
+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`.

+ <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>Drill is designed to maximize data locality:</p>
+

+ <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>

+ <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>

+<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 [...]

+ <article class="post-content">
+ <p>2014 was an exciting year for the Drill community. In August we made Drill available for downloads, and last week the Apache Software Foundation promoted Drill to a top-level project. Many of you have asked me what’s coming next, so I decided to sit down and outline some of the interesting initiatives that the Drill community is currently working on:</p>
+
+<ul>
+ <li>Flexible Access Control</li>
+ <li>JSON in Any Shape or Form</li>
+ <li>Advanced SQL</li>
+ <li>New Data Sources</li>
+ <li>Drill/Spark Integration</li>
+ <li>Operational Enhancements: Speed, Scalability and Workload Management</li>
+</ul>
+
+<p>This is by no means intended to be an exhaustive list of everything that will be added to Drill in 2015. With Drill’s rapidly expanding community, I anticipate that you’ll see a whole lot more.</p>
+
+<h2 id="flexible-access-control">Flexible Access Control</h2>
+
+<p>Many organizations are now interested in providing Drill as a service to their users, supporting many users, groups and organizations with a single cluster. To do so, they need to be able to control who can access what data. Today’s volume and variety of data requires a new approach to access control. For example, it is becoming impractical for organizations to manage a standalone, centralized repository of permissions for every column/row of every table. Drill’s virtual datasets (vie [...]
+
+<ul>
+ <li>The user creates a virtual dataset (<code class="language-plaintext highlighter-rouge">CREATE VIEW vd AS SELECT ...</code>), selecting the data to be exposed/shared. The virtual dataset is defined as a SQL statement. For example, a virtual dataset may represent only the records that were created in the last 30 days and don’t have the <code class="language-plaintext highlighter-rouge">restricted</code> flag. It could even mask some columns. Drill’s virtual datasets (just the SQL sta [...]
+ <li>A virtual dataset is owned by a specific user and can only “select” data that the owner has access to. The data sources (HDFS, HBase, MongoDB, etc.) are responsible for access control decisions. Users and administrators do not need to define separate permissions inside Drill or utilize yet another centralized permission repository, such as Sentry and Ranger.</li>

+<h2 id="json-in-any-shape-or-form">JSON in Any Shape or Form</h2>
+
+<p>When data is <strong>Big</strong> (as in Big Data), it is painful to copy and transform it. Users should be able to explore the raw data without (or at least prior to) transforming it into another format. Drill is designed to enable in-situ analytics. Just point it at a file or directory and run the queries.</p>
+
+<p>JSON has emerged as the most common self-describing format, and Drill is able to query JSON files out of the box. Drill currently assumes that the JSON documents (or records) are stored sequentially in a file:</p>

+<p>However, many JSON-based datasets, ranging from <a href="http://data.gov">data.gov</a> (government) datasets to Twitter API responses, are not organized as simple sequences of JSON documents. In some cases the actual records are listed as elements of an internal array inside a single JSON document. For example, consider the following file, which technically consists of a single JSON document, but really contains three records (under the <code class="language-plaintext highlighter-roug [...]

+<p>While this works today, the dataset is technically a single JSON document, so Drill ends up reading the entire dataset into memory. We’re developing a FLATTEN-pushdown mechanism that will enable the JSON reader to emit the individual records into the downstream operators, thereby making this work with datasets of arbitrary size. Once that’s implemented, users will be able to explore any JSON-based dataset in-situ (ie, without having to transform it).</p>
+
+<h2 id="full-sql">Full SQL</h2>
+
+<p>Unlike the majority of SQL engines for Hadoop and NoSQL databases, which support SQL-like languages (HiveQL, CQL, etc.), Drill is designed from the ground up to be compliant with ANSI SQL. We simply started with a real SQL parser (Apache Calcite, previously known as Optiq). We’re currently implementing the remaining SQL constructs, and plan to support the full TPC-DS suite (with no query modifications) in 2015. Full SQL support makes BI tools work better, and enables users who are pro [...]
+
+<h2 id="new-data-sources">New Data Sources</h2>
+
+<p>Drill is a standalone, distributed SQL engine. It has a pluggable architecture that allows it to support multiple data sources. Drill 0.6 includes storage plugins for:</p>
+
+<ul>
+ <li><a href="https://hadoop.apache.org/docs/current/api/org/apache/hadoop/fs/FileSystem.html">Hadoop File System</a> implementations (local file system, HDFS, MapR-FS, Amazon S3, etc.)</li>
+ <li>HBase and MapR-DB</li>
+ <li>MongoDB</li>
+ <li>Hive Metastore (query any dataset that is registered in Hive Metastore)</li>
+</ul>
+
+<p>A single query can join data from different systems. For example, a query can join user profiles in MongoDB with log files in Hadoop, or datasets in multiple Hadoop clusters.</p>
+
+<p>I’m eager to see what storage plugins the community develops over the next 12 months. In the last few weeks alone, developers in the community have expressed their desire (on the <a href="mailto:dev@drill.apache.org">public list</a>) to develop additional storage plugins for the following data sources:</p>
+
+<ul>
+ <li>Cassandra</li>
+ <li>Solr</li>
+ <li>JDBC (any RDBMS, including Oracle, MySQL, PostgreSQL and SQL Server)</li>
+</ul>
+
+<p>If you’re interested in implementing a new storage plugin, I would encourage you to reach out to the Drill developer community on <a href="mailto:dev@drill.apache.org">dev@drill.apache.org</a>. I’m looking forward to publishing an example of a single-query join across 10 data sources.</p>
+
+<h2 id="drillspark-integration">Drill/Spark Integration</h2>
+
+<p>We’re seeing growing interest in Spark as an execution engine for data pipelines, providing an alternative to MapReduce. The Drill community is working on integrating Drill and Spark to address a few new use cases:</p>
+
+<ul>
+ <li>
+ <p>Use a Drill query (or view) as the input to Spark. Drill is a powerful engine for extracting and pre-processing data from various data sources, thereby reducing development time and effort. Here’s an example:</p>
+
+ <div class="language-scala highlighter-rouge"><div class="highlight"><pre class="highlight"><code> <span class="k">val</span> <span class="nv">sc</span> <span class="k">=</span> <span class="k">new</span> <span class="nc">SparkContext</span><span class="o">(</span><span class="n">conf</span><span class="o">)</span>

+ <span class="n">s</span><span class="s">"$first $last $visits"</span>
+ <span class="o">}</span>
+</code></pre></div> </div>
+ </li>
+ <li>
+ <p>Use Drill to query Spark RDDs. Analysts will be able to use BI tools like MicroStrategy, Spotfire and Tableau to query in-memory data in Spark. In addition, Spark developers will be able to embed Drill execution in a Spark data pipeline, thereby enjoying the power of Drill’s schema-free, columnar execution engine.</p>
+ </li>
+</ul>
+
+<h2 id="operational-enhancements">Operational Enhancements</h2>
+
+<p>As we continue with our monthly releases and march towards the 1.0 release early next year, we’re focused on improving Drill’s speed and scalability. We’ll also enhance Drill’s multi-tenancy with more advanced workload management.</p>
+
+<ul>
+ <li><strong>Speed</strong>: Drill is already extremely fast, and we’re going to make it even faster over the next few months. With that said, we think that improving user productivity and time-to-insight is as important as shaving a few milliseconds off a query’s runtime.</li>
+ <li><strong>Scalability</strong>: To date we’ve focused mainly on clusters of up to a couple hundred nodes. We’re currently working to support clusters with thousands of nodes. We’re also improving concurrency to better support deployments in which hundreds of analysts or developers are running queries at the same time.</li>
+ <li><strong>Workload management</strong>: A single cluster is often shared among many users and groups, and everyone expects answers in real-time. Workload management prioritizes the allocation of resources to ensure that the most important workloads get done first so that business demands can be met. Administrators need to be able to assign priorities and quotas at a fine granularity. We’re working on enhancing Drill’s workload management to provide these capabilities while providing [...]

+ <article class="post-content">
+ <p>JSON has emerged in recent years as the de-facto standard data exchange format. It is being used everywhere. Front-end Web applications use JSON to maintain data and communicate with back-end applications. Web APIs are JSON-based (eg, <a href="https://dev.twitter.com/rest/public">Twitter REST APIs</a>, <a href="http://developers.marketo.com/documentation/rest/">Marketo REST APIs</a>, <a href="https://developer.github.com/v3/">GitHub API</a>). It’s the format of choice for public d [...]
+
+<h1 id="why-is-json-a-convenient-data-exchange-format">Why is JSON a Convenient Data Exchange Format?</h1>
+
+<p>While I won’t dive into the historical roots of JSON (JavaScript Object Notation, <a href="http://en.wikipedia.org/wiki/JSON#JavaScript_eval.28.29"><code class="language-plaintext highlighter-rouge">eval()</code></a>, etc.), I do want to highlight several attributes of JSON that make it a convenient data exchange format:</p>
+
+<ul>
+ <li><strong>JSON is self-describing</strong>. You can look at a JSON document and understand what it represents. The field names are included in the document. You don’t need an external schema or definition to interpret JSON-encoded data. This makes life easier for anyone who wants to deal with the data, and it also means that a collection of JSON documents represents what many people call a “schema-less dataset” (where structure can evolve, and different records can have different fie [...]
+ <li><strong>JSON is simple</strong>. Other self-describing formats such as XML are much more complicated. A JSON document is made up of arrays and maps (or objects, in JSON terminology), and that’s about it.</li>
+ <li><strong>JSON can naturally represent real-world objects</strong>. Try representing your application’s <code class="language-plaintext highlighter-rouge">Customer</code> object (with the person’s address, order history, etc.) in a CSV file or a relational database. It’s hard. In fact, ORM systems were invented to help alleviate this issue.</li>
+ <li><strong>JSON libraries are available in virtually every programming language</strong>. Take a look at <a href="http://www.json.org/">the list of supported languages on JSON.org</a>. I counted 15 languages that start with the letters A, B or C.</li>
+ <li><strong>JSON is idiomatic in loosely typed languages</strong>. Many loosely typed languages, such as Python, Ruby and JavaScript, have data structures that are similar to JSON objects, making it very natural to handle JSON data in those languages. For example, a Python dictionary looks just like a JSON object. This makes it easy for developers to utilize JSON in their applications.</li>
+</ul>
+
+<h1 id="json-data-infrastructure">JSON Data Infrastructure</h1>
+
+<p>Traditional data infrastructure, such as relational databases, has some features that make it easier to store and process JSON-encoded data. For example, Oracle has <a href="https://docs.oracle.com/database/121/ADXDB/json.htm">a JSON data type and a set of functions for handling JSON data</a>.</p>
+
+<p>However, a new class of data infrastructure is providing a much more seamless experience via a full-fledged JSON data model. For example:</p>
+
+<ul>
+ <li>Drill is a SQL engine in which each record is conceptually a JSON document.</li>
+ <li>Elasticsearch is a search engine in which each indexed document is conceptually a JSON document.</li>
+ <li>MongoDB is an operational database in which each record is conceptually a JSON document.</li>
+</ul>
+
+<p>These systems view JSON as a data model as opposed to one of many data types, realizing that JSON offers a simple way to represent real-world objects.</p>

+ <p>Today MicroStrategy <a href="http://ir.microstrategy.com/releasedetail.cfm?ReleaseID=902795">announced</a> that it has certified its platform with Apache Drill. According to MicroStrategy’s CTO, Tim Lang, Drill reduces the time-to-value for MicroStrategy users, and enables them to leverage multi-structured data.</p>
+
+<p>Many early adopters of Drill have been interested in leveraging MicroStrategy’s powerful BI platform. With it’s first-class support for self-describing data and evolving structure, Drill enables MicroStrategy users to explore and analyze the data in Hadoop and NoSQL databases without the usual friction that comes with having to define and manage schemas.</p>

+
+<ul>
+ <li><strong>Bytecode rewriting</strong>. Drill now leverages code optimization techniques such as bytecode rewriting and inlining to enhance the speed of many queries by reducing overall memory usage and CPU instructions.</li>
+ <li><strong>Advanced partition pruning</strong>. Drill can now prune partitions based on arbitrarily complex expressions. For example, specify <code class="language-plaintext highlighter-rouge">WHERE dir0 LIKE '2015-%'</code> and your query will look inside the directory “2015-01” but not inside “2014-12”.</li>
+ <li><strong>Real-time query diagnostics</strong>. You can now see exactly what your queries are doing in real-time, making it easy to troubleshoot, optimize and manage execution.</li>
+ <li><strong>Large records, large # of files</strong>. Drill was previously limited to small records of up to 128KB. It now supports records of any size. In addition, query performance has been improved when dealing with large numbers of files thanks to a variety of optimizations such as parallel metadata reads.</li>
+ <li><strong>More SQL</strong>. Drill now features complete support for <code class="language-plaintext highlighter-rouge">UNION ALL</code> and <code class="language-plaintext highlighter-rouge">COUNT(DISTINCT)</code>. Drill 0.8 also includes new functions such as <code class="language-plaintext highlighter-rouge">unix_timestamp</code> and the window functions <code class="language-plaintext highlighter-rouge">sum</code>, <code class="language-plaintext highlighter-rouge">count</code> a [...]
