+
+<h2 id="flink-110-release">Flink 1.10 Release</h2>
+
+<p>To kick off the new year, the Flink community <a
href="https://flink.apache.org/news/2020/02/11/release-1.10.0.html">released
Flink 1.10</a> with the record contribution of over 200 engineers. This
release introduced significant improvements to the overall performance and
stability of Flink jobs, a preview of native Kubernetes integration and
advances in Python support (PyFlink). Flink 1.10 also marked the completion of
the <a href="https://flink.ap [...]
+
+<p>The community is now discussing the <a

of Flink 1.10.1</a>, covering some outstanding bugs from Flink
1.10.</p>
+
+<h2
id="stateful-functions-contribution-and-20-release">Stateful
Functions Contribution and 2.0 Release</h2>
+
+<p>Last January, the first version of Stateful Functions (<a
href="https://statefun.io/">statefun.io</a>) code was pushed
to the <a href="https://github.com/apache/flink-statefun">Flink
repository</a>. Stateful Functions started out as an API to build general
purpose event-driven applications on Flink, taking advantage of its advanced
state management mechanism to cut the “middleman” that usually handles state
coordination in such applica [...]

update</a>, some new features were announced, like multi-language
support (including a Python SDK), function unit testing and Stateful Functions’
own flavor of the <a

+
+<h2 id="building-up-to-flink-111">Building up to Flink
1.11</h2>
+
+<p>Amidst the usual outpour of discussion threads, JIRA tickets and
FLIPs, the community is working full steam on bringing Flink 1.11 to life in
the next few months. The feature freeze is currently scheduled for late April,
so the release is expected around mid May.
+The upcoming release will focus on new features and integrations that broaden
the scope of Flink use cases, as well as core runtime enhancements to
streamline the operations of complex deployments.</p>
+
+<p>Some of the plans on the use case side include support for changelog
streams in the Table API/SQL (<a
href="https://cwiki.apache.org/confluence/display/FLINK/FLIP-105%3A+Support+to+Interpret+and+Emit+Changelog+in+Flink+SQL">FLIP-105</a>),

and support for Pandas DataFrames in [...]
+
+<p>Throw into the mix improvements around type systems, the WebUI,
metrics reporting and supported formats, this release is bound to keep the
community busy. For a complete overview of the ongoing development, check <a

Flink Repository</h2>
+
+<p>In the <a
href="https://flink.apache.org/news/2019/09/10/community-update.html">last
update</a>, we shared some numbers around Flink releases and mailing
list activity. This time, we’re looking into the activity in the Flink
repository and how it’s evolving.</p>

width="725px" alt="GitHub 1" />
+</center>
+
+<p>There is a clear upward trend in the number of contributions to the
repository, based on the number of commits. This reflects the
<strong>fast pace of development</strong> the project is
experiencing and also the <strong>successful integration of the
China-based Flink contributors</strong> started early last year. To
complement these observations, the repository registered a <strong>1.5x
increase in the number of individual contributors in 2019</ [...]
+
+<p>But did this increase in capacity produce any other measurable
benefits?</p>

+</center>
+
+<p>If we look at the average time of Pull Request (PR) “resolution”, it
seems like it did: <strong>the average time it takes to close a PR these
days has been steadily decreasing</strong> since last year, sitting
between 5-6 days for the past few months.</p>
+
+<p>These are great indicators of the health of Flink as an open source
project!</p>

Room”</a>, a dedicated space in Flink’s Wiki for knowledge sharing
between contributors. The goal of this initiative is to make ongoing
development on Flink internals more transparent across different work streams,
and also to help new contributors get on board with best practices. The first
blogpost is already up and shed [...]

+

Virtual Conference</h2>
+
+<p>The organization of Flink Forward had to make the hard decision of
cancelling this year’s event in San Francisco. But all is not lost!
<strong>Flink Forward SF will be held online on April 22-24 and you can

-
-<h2 id="overview-of-major-new-features">Overview of major new
features</h2>
-
-<p><strong>Flink Streaming:</strong> The gem of the 0.7.0
release is undoubtedly Flink Streaming. Available currently in alpha, Flink
Streaming provides a Java API on top of Apache Flink that can consume streaming
data sources (e.g., from Apache Kafka, Apache Flume, and others) and process
them in real time. A dedicated blog post on Flink Streaming and its performance
is coming up here soon. You can check out the Streaming programming guide <a
href="http://ci.ap [...]
-
-<p><strong>New Scala API:</strong> The Scala API has been
completely rewritten. The Java and Scala APIs have now the same syntax and
transformations and will be kept from now on in sync in every future release.
See the new Scala API <a
href="http://ci.apache.org/projects/flink/flink-docs-release-0.7/programming_guide.html">here</a>.</p>
-
-<p><strong>Logical key expressions:</strong> You can now
specify grouping and joining keys with logical names for member variables of
POJO data types. For example, you can join two data sets as
<code>persons.join(cities).where(“zip”).equalTo(“zipcode”)</code>.
Read more <a
href="http://ci.apache.org/projects/flink/flink-docs-release-0.7/programming_guide.html#specifying-keys">here</a>.</p>
-
-<p><strong>Hadoop MapReduce compatibility:</strong> You can
run unmodified Hadoop Mappers and Reducers (mapred API) in Flink, use all
Hadoop data types, and read data with all Hadoop InputFormats.</p>
-
-<p><strong>Collection-based execution backend:</strong> The
collection-based execution backend enables you to execute a Flink job as a
simple Java collections program, bypassing completely the Flink runtime and
optimizer. This feature is extremely useful for prototyping, and embedding
Flink jobs in projects in a very lightweight manner.</p>
-
-<p><strong>Record API deprecated:</strong> The (old)
Stratosphere Record API has been marked as deprecated and is planned for
removal in the 0.9.0 release.</p>
-
-<p><strong>BLOB service:</strong> This release contains a
new service to distribute jar files and other binary data among the JobManager,
TaskManagers and the client.</p>
-
-<p><strong>Intermediate data sets:</strong> A major rewrite
of the system internals introduces intermediate data sets as first class
citizens. The internal state machine that tracks the distributed tasks has also
been completely rewritten for scalability. While this is not visible as a
user-facing feature yet, it is the foundation for several upcoming exciting
features.</p>
-
-<p><strong>Note:</strong> Currently, there is limited
support for Java 8 lambdas when compiling and running from an IDE. The problem
is due to type erasure and whether Java compilers retain type information. We
are currently working with the Eclipse and OpenJDK communities to resolve
this.</p>

+ <p><p>Nowadays, a lot of open-source systems for analyzing large data
sets are implemented in Java or other JVM-based programming languages. The most
well-known example is Apache Hadoop, but also newer frameworks such as Apache
Spark, Apache Drill, and also Apache Flink run on JVMs. A common challenge that
JVM-based data analysis engines face is to store large amounts of data in

+
+<h2 id="flink-110-release">Flink 1.10 Release</h2>
+
+<p>To kick off the new year, the Flink community <a
href="https://flink.apache.org/news/2020/02/11/release-1.10.0.html";>released
Flink 1.10</a> with the record contribution of over 200 engineers. This release
introduced significant improvements to the overall performance and stability of
Flink jobs, a preview of native Kubernetes integration and advances in Python
support (PyFlink). Flink 1.10 also marked the completion of the <a
href="https://flink.apache.org/news/2019/08/22/release-1.9 [...]
+
+<p>The community is now discussing the <a
href="http://apache-flink-mailing-list-archive.1008284.n3.nabble.com/DISCUSS-Releasing-Flink-1-10-1-td38689.html#a38690";>release
of Flink 1.10.1</a>, covering some outstanding bugs from Flink 1.10.</p>
+
+<h2 id="stateful-functions-contribution-and-20-release">Stateful Functions
Contribution and 2.0 Release</h2>
+
+<p>Last January, the first version of Stateful Functions (<a
href="https://statefun.io/";>statefun.io</a>) code was pushed to the <a
href="https://github.com/apache/flink-statefun";>Flink repository</a>. Stateful
Functions started out as an API to build general purpose event-driven
applications on Flink, taking advantage of its advanced state management
mechanism to cut the “middleman” that usually handles state coordination in
such applications (e.g. a database).</p>
+
+<p>In a <a

update</a>, some new features were announced, like multi-language support
(including a Python SDK), function unit testing and Stateful Functions’ own
flavor of the <a

Processor API</a>. The release cycle will be independen [...]
+
+<h2 id="building-up-to-flink-111">Building up to Flink 1.11</h2>
+
+<p>Amidst the usual outpour of discussion threads, JIRA tickets and FLIPs, the
community is working full steam on bringing Flink 1.11 to life in the next few
months. The feature freeze is currently scheduled for late April, so the
release is expected around mid May.
+The upcoming release will focus on new features and integrations that broaden
the scope of Flink use cases, as well as core runtime enhancements to
streamline the operations of complex deployments.</p>
+
+<p>Some of the plans on the use case side include support for changelog
streams in the Table API/SQL (<a
href="https://cwiki.apache.org/confluence/display/FLINK/FLIP-105%3A+Support+to+Interpret+and+Emit+Changelog+in+Flink+SQL";>FLIP-105</a>),
easy streaming data ingestion into Apache Hive (<a
href="https://cwiki.apache.org/confluence/display/FLINK/FLIP-115%3A+Filesystem+connector+in+Table";>FLIP-115</a>)
and support for Pandas DataFrames in PyFlink. On the operational side, the

+
+<p>Throw into the mix improvements around type systems, the WebUI, metrics
reporting and supported formats, this release is bound to keep the community
busy. For a complete overview of the ongoing development, check <a

+
+<p>In the <a
href="https://flink.apache.org/news/2019/09/10/community-update.html";>last
update</a>, we shared some numbers around Flink releases and mailing list
activity. This time, we’re looking into the activity in the Flink repository
and how it’s evolving.</p>

width="725px" alt="GitHub 1" />
+</center>
+
+<p>There is a clear upward trend in the number of contributions to the
repository, based on the number of commits. This reflects the <strong>fast pace
of development</strong> the project is experiencing and also the
<strong>successful integration of the China-based Flink contributors</strong>
started early last year. To complement these observations, the repository
registered a <strong>1.5x increase in the number of individual contributors in
2019</strong>, compared to the previous year.</p>
+
+<p>But did this increase in capacity produce any other measurable benefits?</p>
+
+<center>

+</center>
+
+<p>If we look at the average time of Pull Request (PR) “resolution”, it seems
like it did: <strong>the average time it takes to close a PR these days has
been steadily decreasing</strong> since last year, sitting between 5-6 days for
the past few months.</p>
+
+<p>These are great indicators of the health of Flink as an open source
project!</p>

Room”</a>, a dedicated space in Flink’s Wiki for knowledge sharing between
contributors. The goal of this initiative is to make ongoing development on
Flink internals more transparent across different work streams, and also to
help new contributors get on board with best practices. The first blogpost is
already up and sheds light on the <a href="http [...]

+
+<p>The organization of Flink Forward had to make the hard decision of
cancelling this year’s event in San Francisco. But all is not lost!
<strong>Flink Forward SF will be held online on April 22-24 and you can
register (for free)</strong> <a

interactive talks and Q&A sessions with core Flink contributors and
companies like Splunk, Lyft, Netflix or Google.</p>

around COVID-19, so this time we’ll leave you with some interesting content to
