+<title>Apache Flink 1.4.0 Release Announcement</title>
+<description><p>The Apache Flink community is pleased to announce the 1.4.0 release. Over the past 5 months, the
+Flink community has been working hard to resolve more than 900 issues. See the <a href="https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12315522&amp;version=12340533">complete changelog</a>
+for more detail.</p>
+
+<p>This is the fifth major release in the 1.x.y series. It is API-compatible with the other 1.x.y
+releases for APIs annotated with the @Public annotation.</p>
+
+<p>We encourage everyone to download the release and check out the <a href="https://ci.apache.org/projects/flink/flink-docs-release-1.4/">documentation</a>.</p>
+
+<p>Feedback through the <a href="http://flink.apache.org/community.html#mailing-lists">Flink mailing lists</a> is, as always, gladly encouraged!</p>
+
+<p>You can find the binaries on the updated <a href="http://flink.apache.org/downloads.html">Downloads</a> page on the Flink project site.</p>
+
+<p>The release includes improvements to many different aspects of Flink, including:</p>
+
+<ul>
+ <li>The ability to build end-to-end exactly-once applications with Flink and popular data sources and sinks such as Apache Kafka.</li>
+ <li>A more developer-friendly dependency structure as well as Hadoop-free Flink for Flink users who do not have Hadoop dependencies.</li>
+ <li>Support for JOIN and for new sources and sinks in table API and SQL, expanding the range of logic that can be expressed with these APIs.</li>
+</ul>
+
+<p>A summary of some of the features in the release is available below.</p>
+
+<p>For more background on the Flink 1.4.0 release and the work planned for the Flink 1.5.0 release, please refer to <a href="http://flink.apache.org/news/2017/11/22/release-1.4-and-1.5-timeline.html">this blog post</a> on the Apache Flink blog.</p>
+
+<h2 id="new-features-and-improvements">New Features and Improvements</h2>
+
+<h3 id="end-to-end-exactly-once-applications-with-apache-flink-and-apache-kafka-and-twophasecommitsinkfunction">End-to-end Exactly Once Applications with Apache Flink and Apache Kafka and TwoPhaseCommitSinkFunction</h3>
+
+<p>Flink 1.4 includes a first version of an exactly-once producer for Apache Kafka 0.11. This producer
+enables developers who build Flink applications with Kafka as a data source and sink to compute
+exactly-once results not just within the Flink program, but truly “end-to-end” in the application.</p>
+
+<p>The common pattern used for exactly-once applications in Kafka and in other sinks–the two-phase
+commit algorithm–has been extracted in Flink 1.4.0 into a common class, the
+TwoPhaseCommitSinkFunction (<a href="https://issues.apache.org/jira/browse/FLINK-7210">FLINK-7210</a>). This
+will make it easier for users to create their own exactly-once data sinks in the future.</p>
+
+<h3 id="table-api-and-streaming-sql-enhancements">Table API and Streaming SQL Enhancements</h3>
+
+<p>Flink SQL now supports windowed joins based on processing time and event time
+(<a href="https://issues.apache.org/jira/browse/FLINK-5725">FLINK-5725</a>). Users will be able to execute a
+join between 2 streaming tables and compute windowed results according to these 2 different concepts
+of time. The syntax and semantics in Flink are the same as standard SQL with JOIN and with Flink’s
+streaming SQL more broadly.</p>
+
+<p>Flink SQL also now supports “INSERT INTO SELECT” queries, which makes it possible to write results
+from SQL directly into a data sink (an external system that receives data from a Flink application).
+This improves operability and ease-of-use of Flink SQL.</p>
+
+<p>The Table API now supports aggregations on streaming tables; previously, the only supported
+operations on streaming tables were projection, selection, and union
+(<a href="https://issues.apache.org/jira/browse/FLINK-4557">FLINK-4557</a>). This feature was initially discussed in Flink
+Improvement Proposal 11: <a href="https://cwiki.apache.org/confluence/display/FLINK/FLIP-11%3A+Table+API+Stream+Aggregations">FLIP-11</a>.</p>
+
+<p>The release also adds support for new table API and SQL sources and sinks, including a Kafka 0.11
+source and JDBC sink.</p>
+
+<p>Lastly, Flink SQL now uses Apache Calcite 1.14, which was just released in October 2017
+(<a href="https://issues.apache.org/jira/browse/FLINK-7051">FLINK-7051</a>).</p>
+
+<h3 id="a-significantly-improved-dependency-structure-and-reversed-class-loading">A Significantly-Improved Dependency Structure and Reversed Class Loading</h3>
+
+<p>Flink 1.4.0 shades a number of dependences and subtle runtime conflicts, including:</p>
+
+<ul>
+ <li>ASM</li>
+ <li>Guava</li>
+ <li>Jackson</li>
+ <li>Netty</li>
+ <li>Apache Zookeeper</li>
+</ul>
+
+<p>These changes improve Flink’s overall stability and removes friction when embedding Flink or calling
+Flink “library style”.</p>
+
+<p>The release also introduces default reversed (child-first) class loading for dynamically-loaded user
+code, allowing for different dependencies than those included in the core framework.</p>
+
+<p>For details on those changes please check out the relevant Jira issues:</p>
+
+<ul>
+ <li><a href="https://issues.apache.org/jira/browse/FLINK-7442">FLINK-7442</a></li>
+ <li><a href="https://issues.apache.org/jira/browse/FLINK-6529">FLINK-6529</a></li>
+</ul>
+
+<h3 id="hadoop-free-flink">Hadoop-free Flink</h3>
+
+<p>Apache Flink users without any Apache Hadoop dependencies can now run Flink without Hadoop. Flink
+programs that do not rely on Hadoop components can now be much smaller, a benefit particularly in a
+container-based setup resulting in less network traffic and better performance.</p>
+
+<p>This includes the addition of Flink’s own Amazon S3 filesystem implementations based on Hadoop’s S3a
+and Presto’s S3 file system with properly shaded dependencies (<a href="https://issues.apache.org/jira/browse/FLINK-5706">FLINK-5706</a>).</p>
+
+<p>The details of these changes regarding Hadoop-free Flink are available in the Jira issue:
+<a href="https://issues.apache.org/jira/browse/FLINK-2268">FLINK-2268</a>.</p>
+
+<h3 id="improvements-to-flink-internals">Improvements to Flink Internals</h3>
+
+<p>Flink 1.4.0 introduces a new blob storage architecture that was first discussed in
+<a href="https://cwiki.apache.org/confluence/display/FLINK/FLIP-19%3A+Improved+BLOB+storage+architecture">Flink Improvement Proposal 19</a> (<a href="https://issues.apache.org/jira/browse/FLINK-6916">FLINK-6916</a>).</p>
+
+<p>This will enable easier integration with both the work being done in <a href="https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=65147077">Flink Improvement Proposal 6</a> in
+the future and with other improvements in the 1.4.0 release, such as support for messages larger
+than the maximum Akka Framesize (<a href="https://issues.apache.org/jira/browse/FLINK-6046">FLINK-6046</a>).</p>
+
+<p>The improvement also enables Flink to leverage distributed file systems in high availability
+settings for optimized distribution of deployment data to TaskManagers.</p>
+
+<h3 id="improvements-to-the-queryable-state-client">Improvements to the Queryable State Client</h3>
+
+<p>Flink’s <a href="https://ci.apache.org/projects/flink/flink-docs-release-1.4/dev/stream/state/queryable_state.html">queryable state</a> makes it possible for users to access application state directly in Flink
+before the state has been sent to an external database or key-value store.</p>
+
+<p>Flink 1.4.0 introduces a range of improvements to the queryable state client, including a more
+container-friendly architecture, a more user-friendly API that hides configuration parameters, and
+the groundwork to be able to expose window state (the state of an in-flight window) in the future.</p>
+
+<p>For details about the changes to queryable state please refer to the umbrella Jira issue:
+<a href="https://issues.apache.org/jira/browse/FLINK-5675">FLINK-5675</a>.</p>
+
+<h3 id="metrics-and-monitoring">Metrics and Monitoring</h3>
+
+<p>Flink’s metrics system now also includes support for Prometheus, an increasingly-popular metrics and
+reporting system within the Flink community (<a href="https://issues.apache.org/jira/browse/FLINK-6221">FLINK-6221</a>).</p>
+
+<p>And the Apache Kafka connector in Flink now exposes metrics for failed and successful offset commits
+in the Kafka consumer callback (<a href="https://issues.apache.org/jira/browse/FLINK-6998">FLINK-6998</a>).</p>
+
+<h3 id="connector-improvements-and-fixes">Connector improvements and fixes</h3>
+
+<p>Flink 1.4.0 introduces an Apache Kafka 0.11 connector and, as described above, support for an
+exactly-once producer for Kafka 0.11 (<a href="https://issues.apache.org/jira/browse/FLINK-6988">FLINK-6988</a>).</p>
+
+<p>Additionally, the Flink-Kafka consumer now supports dynamic partition discovery &amp; topic discovery
+based on regex. This means that the Flink-Kafka consumer can pick up new Kafka partitions without
+needing to restart the job and while maintaining exactly-once guarantees
+(<a href="https://issues.apache.org/jira/browse/FLINK-4022">FLINK-4022</a>).</p>
+
+<p>Flink’s Apache Kinesis connector now uses an updated version of the Kinesis Consumer Library and
+Kinesis Consumer Library. This introduces improved retry logic to the connector and should
+significantly reduce the number of failures caused by Flink writing too quickly to Kinesis
+(<a href="https://issues.apache.org/jira/browse/FLINK-7366">FLINK-7366</a>).</p>
+
+<p>Flink’s Apache Cassandra connector now supports Scala tuples–previously, only streams of Java
+tuples were supported (<a href="https://issues.apache.org/jira/browse/FLINK-4497">FLINK-4497</a>). Also, a bug was fixed in
+the Cassandra connector that caused messages to be lost in certain instances
+(<a href="https://issues.apache.org/jira/browse/FLINK-4500">FLINK-4500</a>).</p>
+
+<h2 id="release-notes---please-read">Release Notes - Please Read</h2>
+
+<p>Some of these changes will require updating the configuration or Maven dependencies for existing
+programs. Please read below to see if you might be affected.</p>
+
+<h3 id="changes-to-dynamic-class-loading-of-user-code">Changes to dynamic class loading of user code</h3>
+
+<p>As mentioned above, we changed the way Flink loads user code from the previous default of
+<em>parent-first class loading</em> (the default for Java) to <em>child-first classloading</em>, which is a common
+practice in Java Application Servers, where this is also referred to as inverted or reversed class
+loading.</p>
+
+<p>This should not affect regular user code but will enable programs to use a different version of
+dependencies that come with Flink – for example Akka, netty, or Jackson. If you want to change back
+to the previous default, you can use the configuration setting <code>classloader.resolve-order: parent-first</code>,
+the new default being <code>child-first</code>.</p>
+
+<h3 id="no-more-avro-dependency-included-by-default">No more Avro dependency included by default</h3>
+
+<p>Flink previously included Avro by default so user programs could simply use Avro and not worry about
+adding any dependencies. This behavior was changed in Flink 1.4 because it can lead to dependency
+clashes.</p>
+
+<p>You now must manually include the Avro dependency (<code>flink-avro</code>) with your program jar (or add it to
+the Flink lib folder) if you want to use Avro.</p>
+
+<h3 id="hadoop-free-flink-1">Hadoop-free Flink</h3>
+
+<p>Starting with version 1.4, Flink can run without any Hadoop dependencies present in the Classpath.
+Along with simply running without Hadoop, this enables Flink to dynamically use whatever Hadoop
+version is available in the classpath.</p>
+
+<p>You could, for example, download the Hadoop-free release of Flink but use that to run on any
+supported version of YARN, and Flink would dynamically use the Hadoop dependencies from YARN.</p>
+
+<p>This also means that in cases where you used connectors to HDFS, such as the <code>BucketingSink</code> or
+<code>RollingSink</code>, you now have to ensure that you either use a Flink distribution with bundled Hadoop
+dependencies or make sure to include Hadoop dependencies when building a jar file for your
+application.</p>

+ <h1>Apache Flink 1.4.0 Release Announcement</h1>
+
+ <article>
+ <p>12 Dec 2017 Aljoscha Krettek (<a href="https://twitter.com/aljoscha">@aljoscha</a>) & Mike Winters (<a href="https://twitter.com/wints">@wints</a>)</p>
+
+<p>The Apache Flink community is pleased to announce the 1.4.0 release. Over the past 5 months, the
+Flink community has been working hard to resolve more than 900 issues. See the <a href="https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12315522&version=12340533">complete changelog</a>
+for more detail.</p>
+
+<p>This is the fifth major release in the 1.x.y series. It is API-compatible with the other 1.x.y
+releases for APIs annotated with the @Public annotation.</p>
+
+<p>We encourage everyone to download the release and check out the <a href="https://ci.apache.org/projects/flink/flink-docs-release-1.4/">documentation</a>.</p>
+
+<p>Feedback through the <a href="http://flink.apache.org/community.html#mailing-lists">Flink mailing lists</a> is, as always, gladly encouraged!</p>
+
+<p>You can find the binaries on the updated <a href="http://flink.apache.org/downloads.html">Downloads</a> page on the Flink project site.</p>
+
+<p>The release includes improvements to many different aspects of Flink, including:</p>
+
+<ul>
+ <li>The ability to build end-to-end exactly-once applications with Flink and popular data sources and sinks such as Apache Kafka.</li>
+ <li>A more developer-friendly dependency structure as well as Hadoop-free Flink for Flink users who do not have Hadoop dependencies.</li>
+ <li>Support for JOIN and for new sources and sinks in table API and SQL, expanding the range of logic that can be expressed with these APIs.</li>
+</ul>
+
+<p>A summary of some of the features in the release is available below.</p>
+
+<p>For more background on the Flink 1.4.0 release and the work planned for the Flink 1.5.0 release, please refer to <a href="http://flink.apache.org/news/2017/11/22/release-1.4-and-1.5-timeline.html">this blog post</a> on the Apache Flink blog.</p>
+
+<h2 id="new-features-and-improvements">New Features and Improvements</h2>
+
+<h3 id="end-to-end-exactly-once-applications-with-apache-flink-and-apache-kafka-and-twophasecommitsinkfunction">End-to-end Exactly Once Applications with Apache Flink and Apache Kafka and TwoPhaseCommitSinkFunction</h3>
+
+<p>Flink 1.4 includes a first version of an exactly-once producer for Apache Kafka 0.11. This producer
+enables developers who build Flink applications with Kafka as a data source and sink to compute
+exactly-once results not just within the Flink program, but truly “end-to-end” in the application.</p>
+
+<p>The common pattern used for exactly-once applications in Kafka and in other sinks–the two-phase
+commit algorithm–has been extracted in Flink 1.4.0 into a common class, the
+TwoPhaseCommitSinkFunction (<a href="https://issues.apache.org/jira/browse/FLINK-7210">FLINK-7210</a>). This
+will make it easier for users to create their own exactly-once data sinks in the future.</p>
+
+<h3 id="table-api-and-streaming-sql-enhancements">Table API and Streaming SQL Enhancements</h3>
+
+<p>Flink SQL now supports windowed joins based on processing time and event time
+(<a href="https://issues.apache.org/jira/browse/FLINK-5725">FLINK-5725</a>). Users will be able to execute a
+join between 2 streaming tables and compute windowed results according to these 2 different concepts
+of time. The syntax and semantics in Flink are the same as standard SQL with JOIN and with Flink’s
+streaming SQL more broadly.</p>
+
+<p>Flink SQL also now supports “INSERT INTO SELECT” queries, which makes it possible to write results
+from SQL directly into a data sink (an external system that receives data from a Flink application).
+This improves operability and ease-of-use of Flink SQL.</p>
+
+<p>The Table API now supports aggregations on streaming tables; previously, the only supported
+operations on streaming tables were projection, selection, and union
+(<a href="https://issues.apache.org/jira/browse/FLINK-4557">FLINK-4557</a>). This feature was initially discussed in Flink
+Improvement Proposal 11: <a href="https://cwiki.apache.org/confluence/display/FLINK/FLIP-11%3A+Table+API+Stream+Aggregations">FLIP-11</a>.</p>
+
+<p>The release also adds support for new table API and SQL sources and sinks, including a Kafka 0.11
+source and JDBC sink.</p>
+
+<p>Lastly, Flink SQL now uses Apache Calcite 1.14, which was just released in October 2017
+(<a href="https://issues.apache.org/jira/browse/FLINK-7051">FLINK-7051</a>).</p>
+
+<h3 id="a-significantly-improved-dependency-structure-and-reversed-class-loading">A Significantly-Improved Dependency Structure and Reversed Class Loading</h3>
+
+<p>Flink 1.4.0 shades a number of dependences and subtle runtime conflicts, including:</p>
+
+<ul>
+ <li>ASM</li>
+ <li>Guava</li>
+ <li>Jackson</li>
+ <li>Netty</li>
+ <li>Apache Zookeeper</li>
+</ul>
+
+<p>These changes improve Flink’s overall stability and removes friction when embedding Flink or calling
+Flink “library style”.</p>
+
+<p>The release also introduces default reversed (child-first) class loading for dynamically-loaded user
+code, allowing for different dependencies than those included in the core framework.</p>
+
+<p>For details on those changes please check out the relevant Jira issues:</p>
+
+<ul>
+ <li><a href="https://issues.apache.org/jira/browse/FLINK-7442">FLINK-7442</a></li>
+ <li><a href="https://issues.apache.org/jira/browse/FLINK-6529">FLINK-6529</a></li>
+</ul>
+
+<h3 id="hadoop-free-flink">Hadoop-free Flink</h3>
+
+<p>Apache Flink users without any Apache Hadoop dependencies can now run Flink without Hadoop. Flink
+programs that do not rely on Hadoop components can now be much smaller, a benefit particularly in a
+container-based setup resulting in less network traffic and better performance.</p>
+
+<p>This includes the addition of Flink’s own Amazon S3 filesystem implementations based on Hadoop’s S3a
+and Presto’s S3 file system with properly shaded dependencies (<a href="https://issues.apache.org/jira/browse/FLINK-5706">FLINK-5706</a>).</p>
+
+<p>The details of these changes regarding Hadoop-free Flink are available in the Jira issue:
+<a href="https://issues.apache.org/jira/browse/FLINK-2268">FLINK-2268</a>.</p>
+
+<h3 id="improvements-to-flink-internals">Improvements to Flink Internals</h3>
+
+<p>Flink 1.4.0 introduces a new blob storage architecture that was first discussed in
+<a href="https://cwiki.apache.org/confluence/display/FLINK/FLIP-19%3A+Improved+BLOB+storage+architecture">Flink Improvement Proposal 19</a> (<a href="https://issues.apache.org/jira/browse/FLINK-6916">FLINK-6916</a>).</p>
+
+<p>This will enable easier integration with both the work being done in <a href="https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=65147077">Flink Improvement Proposal 6</a> in
+the future and with other improvements in the 1.4.0 release, such as support for messages larger
+than the maximum Akka Framesize (<a href="https://issues.apache.org/jira/browse/FLINK-6046">FLINK-6046</a>).</p>
+
+<p>The improvement also enables Flink to leverage distributed file systems in high availability
+settings for optimized distribution of deployment data to TaskManagers.</p>
+
+<h3 id="improvements-to-the-queryable-state-client">Improvements to the Queryable State Client</h3>
+
+<p>Flink’s <a href="https://ci.apache.org/projects/flink/flink-docs-release-1.4/dev/stream/state/queryable_state.html">queryable state</a> makes it possible for users to access application state directly in Flink
+before the state has been sent to an external database or key-value store.</p>
+
+<p>Flink 1.4.0 introduces a range of improvements to the queryable state client, including a more
+container-friendly architecture, a more user-friendly API that hides configuration parameters, and
+the groundwork to be able to expose window state (the state of an in-flight window) in the future.</p>
+
+<p>For details about the changes to queryable state please refer to the umbrella Jira issue:
+<a href="https://issues.apache.org/jira/browse/FLINK-5675">FLINK-5675</a>.</p>
+
+<h3 id="metrics-and-monitoring">Metrics and Monitoring</h3>
+
+<p>Flink’s metrics system now also includes support for Prometheus, an increasingly-popular metrics and
+reporting system within the Flink community (<a href="https://issues.apache.org/jira/browse/FLINK-6221">FLINK-6221</a>).</p>
+
+<p>And the Apache Kafka connector in Flink now exposes metrics for failed and successful offset commits
+in the Kafka consumer callback (<a href="https://issues.apache.org/jira/browse/FLINK-6998">FLINK-6998</a>).</p>
+
+<h3 id="connector-improvements-and-fixes">Connector improvements and fixes</h3>
+
+<p>Flink 1.4.0 introduces an Apache Kafka 0.11 connector and, as described above, support for an
+exactly-once producer for Kafka 0.11 (<a href="https://issues.apache.org/jira/browse/FLINK-6988">FLINK-6988</a>).</p>
+
+<p>Additionally, the Flink-Kafka consumer now supports dynamic partition discovery & topic discovery
+based on regex. This means that the Flink-Kafka consumer can pick up new Kafka partitions without
+needing to restart the job and while maintaining exactly-once guarantees
+(<a href="https://issues.apache.org/jira/browse/FLINK-4022">FLINK-4022</a>).</p>
+
+<p>Flink’s Apache Kinesis connector now uses an updated version of the Kinesis Consumer Library and
+Kinesis Consumer Library. This introduces improved retry logic to the connector and should
+significantly reduce the number of failures caused by Flink writing too quickly to Kinesis
+(<a href="https://issues.apache.org/jira/browse/FLINK-7366">FLINK-7366</a>).</p>
+
+<p>Flink’s Apache Cassandra connector now supports Scala tuples–previously, only streams of Java
+tuples were supported (<a href="https://issues.apache.org/jira/browse/FLINK-4497">FLINK-4497</a>). Also, a bug was fixed in
+the Cassandra connector that caused messages to be lost in certain instances
+(<a href="https://issues.apache.org/jira/browse/FLINK-4500">FLINK-4500</a>).</p>
+
+<h2 id="release-notes---please-read">Release Notes - Please Read</h2>
+
+<p>Some of these changes will require updating the configuration or Maven dependencies for existing
+programs. Please read below to see if you might be affected.</p>
+
+<h3 id="changes-to-dynamic-class-loading-of-user-code">Changes to dynamic class loading of user code</h3>
+
+<p>As mentioned above, we changed the way Flink loads user code from the previous default of
+<em>parent-first class loading</em> (the default for Java) to <em>child-first classloading</em>, which is a common
+practice in Java Application Servers, where this is also referred to as inverted or reversed class
+loading.</p>
+
+<p>This should not affect regular user code but will enable programs to use a different version of
+dependencies that come with Flink – for example Akka, netty, or Jackson. If you want to change back
+to the previous default, you can use the configuration setting <code>classloader.resolve-order: parent-first</code>,
+the new default being <code>child-first</code>.</p>
+
+<h3 id="no-more-avro-dependency-included-by-default">No more Avro dependency included by default</h3>
+
+<p>Flink previously included Avro by default so user programs could simply use Avro and not worry about
+adding any dependencies. This behavior was changed in Flink 1.4 because it can lead to dependency
+clashes.</p>
+
+<p>You now must manually include the Avro dependency (<code>flink-avro</code>) with your program jar (or add it to
+the Flink lib folder) if you want to use Avro.</p>
+
+<h3 id="hadoop-free-flink-1">Hadoop-free Flink</h3>
+
+<p>Starting with version 1.4, Flink can run without any Hadoop dependencies present in the Classpath.
+Along with simply running without Hadoop, this enables Flink to dynamically use whatever Hadoop
+version is available in the classpath.</p>
+
+<p>You could, for example, download the Hadoop-free release of Flink but use that to run on any
+supported version of YARN, and Flink would dynamically use the Hadoop dependencies from YARN.</p>
+
+<p>This also means that in cases where you used connectors to HDFS, such as the <code>BucketingSink</code> or
+<code>RollingSink</code>, you now have to ensure that you either use a Flink distribution with bundled Hadoop
+dependencies or make sure to include Hadoop dependencies when building a jar file for your
+application.</p>
