+This has been an exciting, fast-paced year for the Apache Flink community. But
with over 10k messages across the mailing lists, 3k Jira tickets and 2k pull
requests, it is not easy to keep up with the latest state of the project. Plus
everything happening around it. With that in mind, we want to bring back
regular community updates to the Flink blog.
+
+The first post in the series takes you on an little detour across the year, to
freshen up and make sure you're all up to date.

+
+# The Year (so far) in Flink
+
+Two major versions were released this year: [Flink
1.8](https://flink.apache.org/news/2019/04/09/release-1.8.0.html) and [Flink
1.9](https://flink.apache.org/news/2019/08/22/release-1.9.0.html); paving the
way for the goal of making Flink the first framework to seamlessly support
stream and batch processing with a single, unified runtime. The [contribution
of
Blink](https://flink.apache.org/news/2019/02/13/unified-batch-streaming-blink.html)
to Apache Flink was key in accelerating the pa [...]
+
+The 1.9 release was the result of the **biggest community effort the project
has experienced so far**, with the number of contributors soaring to 190 (see
[The Bigger Picture](#the-bigger-picture)). For a quick overview of the
upcoming work for Flink 1.10 (and beyond), have a look at the updated
[roadmap](https://flink.apache.org/roadmap.html)!
+
+## Integration of the Chinese-speaking community
+
+As the number of Chinese-speaking Flink users rapidly grows, the community is
working on translating resources and creating dedicated spaces for discussion
to invite and include these users in the wider Flink community. Part of the
ongoing work is described in
[FLIP-35](https://cwiki.apache.org/confluence/display/FLINK/FLIP-35%3A+Support+Chinese+Documents+and+Website)
and has resulted in:
+
+* A new user mailing list (user-zh@f.a.o) dedicated to Chinese-speakers.
+<p></p>
+* A Chinese translation of the Apache Flink
[website](https://flink.apache.org/zh/) and
[documentation](https://ci.apache.org/projects/flink/flink-docs-master/zh/).
+<p></p>
+* Multiple meetups organized all over China, with the biggest one reaching a
whopping number of 500+ participants. Some of these meetups were also organized
in collaboration with communities from other projects, like Apache Pulsar and
Apache Kafka.

+
+In case you're interested in knowing more about this work in progress, Robert
Metzger and Fabian Hueske will be diving into "Inviting Apache Flink's Chinese
User Community" at the upcoming ApacheCon Europe 2019 (see [Upcoming Flink
Community Events](#upcoming-flink-community-events)).
+
+## Improving Flink's Documentation
+
+Besides the translation effort, the community has also been working quite hard
on a **Flink docs overhaul**. The main goals are to:
+
+ * Organize and clean-up the structure of the docs;
+ <p></p>
+ * Align the content with the overall direction of the project;
+ <p></p>
+ * Improve the _getting-started_ material and make the content more accessible
to different levels of Flink experience.
+
+Given that there has been some confusion in the past regarding unclear
definition of core Flink concepts, one of the first completed efforts was to
introduce a
[Glossary](https://ci.apache.org/projects/flink/flink-docs-release-1.9/concepts/glossary.html#glossary)
in the docs. To get up to speed with the roadmap for the remainder efforts,
you can refer to
[FLIP-42](https://cwiki.apache.org/confluence/display/FLINK/FLIP-42%3A+Rework+Flink+Documentation)
and the corresponding [umbrella Jira [...]
+
+## Adjusting the Contribution Process and Experience
+
+The [guidelines](https://flink.apache.org/contributing/how-to-contribute.html)
to contribute to Apache Flink have been reworked on the website, in an effort
to lower the entry barrier for new contributors and reduce the overall friction
in the contribution process. In addition, the Flink community discussed and
adopted
[bylaws](https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=120731026)
to help the community collaborate and coordinate more smoothly.
+
+For code contributors, a [Code Style and Quality
Guide](https://flink.apache.org/contributing/code-style-and-quality-preamble.html)
that captures the expected standards for contributions was also added to the
"Contributing" section of the Flink website.
+
+It's important to stress that **contributions are not restricted to code**.
Non-code contributions such as mailing list support, documentation work or
organization of community events are equally as important to the development of
the project and highly encouraged.
+
+## New Committers and PMC Members
+
+The Apache Flink community has welcomed **5 new Committers** and **4 PMC
(Project Management Committee) Members** in 2019, so far:
+
+### New PMC Members
+ Jincheng Sun, Kete (Kurt) Young, Kostas Kloudas, Thomas Weise
+
+### New Committers
+ Andrey Zagrebin, Hequn, Jiangjie (Becket) Qin, Rong Rong, Zhijiang Wang
+
+Congratulations and thank you for your hardworking commitment to Flink!
+
+# The Bigger Picture
+
+Flink continues to push the boundaries of (stream) data processing, and the
community is proud to see an ever-increasingly diverse set of contributors,
users and technologies join the ecosystem.
+
+In the timeframe of three releases, the project jumped from **112 to 190
contributors**, also doubling down on the number of requested changes and
improvements. To top it off, the Flink GitHub repository recently reached the
milestone of **10k stars**, all the way up from the incubation days in 2014.

+
+The activity across the user@ and dev@<sup>1</sup> mailing lists shows a
healthy heartbeat, and the gradual ramp up of user-zh@ suggests that this was a
well-received community effort. Looking at the numbers for the same period in
2018, the dev@ mailing list has seen the biggest surge in activity, with an
average growth of **2.5x in the number of messages and distinct users** — a
great reflection of the hyperactive pace of development of the Flink codebase.

+In support of these observations, the report for the financial year of 2019
from the Apache Software Foundation (ASF) features Flink as one of the most
thriving open source projects, with mentions for:
