| <h1>Flink Community Update - May'20</h1> |
| <p><i></i></p> |
| |
| <article> |
| <p>07 May 2020 Marta Paes (<a href="https://twitter.com/morsapaes">@morsapaes</a>)</p> |
| |
| <p>Can you smell it? It’s release month! It took a while, but now that we’re <a href="https://flink.apache.org/news/2020/04/01/community-update.html">all caught up with the past</a>, the Community Update is here to stay. This time around, we’re warming up for Flink 1.11 and peeping back to the month of April in the Flink community — with the release of Stateful Functions 2.0, a new self-paced Flink training and some efforts to improve the Flink documentation experience.</p> |
| |
| <p>Last month also marked the debut of Flink Forward Virtual Conference 2020: what did you think? If you missed it altogether or just want to recap some of the sessions, the <a href="https://www.youtube.com/playlist?list=PLDX4T_cnKjD0ngnBSU-bYGfgVv17MiwA7">videos</a> and <a href="https://www.slideshare.net/FlinkForward">slides</a> are now available!</p> |

| |
| <p>In the beginning of April, the Flink community announced the <a href="https://flink.apache.org/news/2020/04/07/release-statefun-2.0.0.html">release of Stateful Functions 2.0</a> — the first as part of the Apache Flink project. From this release, you can use Flink as the base of a (stateful) serverless platform with out-of-the-box consistent and scalable state, and efficient messaging between functions. You can even run your stateful functions on platforms like AWS Lambda, as Gordon (<a href="https://twitter.com/tzulitai">@tzulitai</a>) demonstrated in <a href="https://www.youtube.com/watch?v=tuSylBadNSo&list=PLDX4T_cnKjD0ngnBSU-bYGfgVv17MiwA7&index=27&t=8s">his Flink Forward talk</a>.</p> |

| <div style="line-height:60%;"> |
| <br /> |
| </div> |
| |
| <p>It’s been encouraging to see so many questions about Stateful Functions popping up in the <a href="https://lists.apache.org/list.html?user@flink.apache.org:lte=3M:statefun">mailing list</a> and Stack Overflow! If you’d like to get involved, we’re always <a href="https://github.com/apache/flink-statefun#contributing">looking for new contributors</a> — especially around SDKs for other languages like Go, Javascript and Rust.</p> |

| |
| <h2 id="warming-up-for-flink-111">Warming up for Flink 1.11</h2> |
| |
| <p>The final preparations for the release of Flink 1.11 are well underway, with the feature freeze scheduled for May 15th, and there’s a lot of new features and improvements to look out for:</p> |
| |
| <ul> |
| <li> |
| <p>On the <strong>usability</strong> side, you can expect a big focus on smoothing data ingestion with contributions like support for Change Data Capture (CDC) 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>) or support for Pandas DataFrames in PyFlink (<a href="https://cwiki.apache.org/confluence/display/FLINK/FLIP-120%3A+Support+conversion+between+PyFlink+Table+and+Pandas+DataFrame">FLIP-120</a>). A great deal of effort has also gone into maturing PyFlink, with the introduction of user defined metrics in Python UDFs (<a href="https://cwiki.apache.org/confluence/display/FLINK/FLIP-112%3A+Support+User-Defined+Metrics+in++Python+UDF">FLIP-112</a>) and the extension of Python UDF support beyond the Python Table API (<a href="https://cwiki.apache.org/confluence/display/FLINK/FLIP-106%3A+Support+Python+UDF+in+SQL+Function+DDL">FLIP-106</a>,<a href="https://cwiki.apache.org/confluence/display/FLINK/FLIP-114%3A+Support+Python+UDF+in+SQL+Client">FLIP-114</a>).</p> |
| </li> |
| <li> |
| <p>On the <strong>operational</strong> side, the much anticipated new Source API (<a href="https://cwiki.apache.org/confluence/display/FLINK/FLIP-27%3A+Refactor+Source+Interface">FLIP-27</a>) will unify batch and streaming sources, and improve out-of-the-box event-time behavior; while unaligned checkpoints (<a href="https://cwiki.apache.org/confluence/display/FLINK/FLIP-76%3A+Unaligned+Checkpoints">FLIP-76</a>) and changes to network memory management will allow to speed up checkpointing under backpressure — this is part of a bigger effort to rethink fault tolerance that will introduce many other non-trivial changes to Flink. You can learn more about it in <a href="https://youtu.be/ssEmeLcL5Uk">this</a> recent Flink Forward talk!</p> |
| </li> |
| </ul> |
| |
| <p>Throw into the mix improvements around type systems, the WebUI, metrics reporting, supported formats and…we can’t wait! To get an overview of the ongoing developments, have a look at <a href="http://apache-flink-mailing-list-archive.1008284.n3.nabble.com/ANNOUNCE-Development-progress-of-Apache-Flink-1-11-tp40718.html">this thread</a>. We encourage the community to get involved in testing once an RC (Release Candidate) is out. Keep an eye on the <a href="https://flink.apache.org/community.html#mailing-lists">@dev mailing list</a> for updates!</p> |

| |
| <h2 id="flink-minor-releases">Flink Minor Releases</h2> |
| |
| <h3 id="flink-193">Flink 1.9.3</h3> |
| |
| <p>The community released Flink 1.9.3, covering some outstanding bugs from Flink 1.9! You can find more in the <a href="(https://flink.apache.org/news/2020/04/24/release-1.9.3.html)">announcement blogpost</a>.</p> |
| |
| <h3 id="flink-1101">Flink 1.10.1</h3> |
| |
| <p>Also in the pipeline is the release of Flink 1.10.1, already in the <a href="http://apache-flink-mailing-list-archive.1008284.n3.nabble.com/VOTE-Release-1-10-1-release-candidate-2-td41019.html">RC voting</a> phase. So, you can expect Flink 1.10.1 to be released soon!</p> |

| </div> |
| |
| <p>This week, the Flink website received the invaluable contribution of a self-paced training course curated by David (<a href="https://twitter.com/alpinegizmo">@alpinegizmo</a>) — or, what used to be the entire training materials under <a href="training.ververica.com">training.ververica.com</a>. The new materials guide you through the very basics of Flink and the DataStream API, and round off every concepts section with hands-on exercises to help you better assimilate what you learned.</p> |

| <p>Whether you’re new to Flink or just looking to strengthen your foundations, this training is the most comprehensive way to get started and is now completely open source: <a href="https://flink.apache.org/training.html">https://flink.apache.org/training.html</a>. For now, the materials are only available in English, but the community intends to also provide a Chinese translation in the future.</p> |

| <h2 id="google-season-of-docs-2020">Google Season of Docs 2020</h2> |
| |
| <p>Google Season of Docs (GSOD) is a great initiative organized by <a href="https://opensource.google.com/">Google Open Source</a> to pair technical writers with mentors to work on documentation for open source projects. Last year, the Flink community submitted <a href="https://flink.apache.org/news/2019/04/17/sod.html">an application</a> that unfortunately didn’t make the cut — but we are trying again! This time, with a project idea to improve the Table API & SQL documentation:</p> |
| |
| <p><strong>1) Restructure the Table API & SQL Documentation</strong></p> |
| |
| <p>Reworking the current documentation structure would allow to:</p> |
| |
| <ul> |
| <li> |
| <p>Lower the entry barrier to Flink for non-programmatic (i.e. SQL) users.</p> |
| </li> |
| <li> |
| <p>Make the available features more easily discoverable.</p> |
| </li> |
| <li> |
| <p>Improve the flow and logical correlation of topics.</p> |
| </li> |
| </ul> |
| |
| <p><a href="https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=127405685">FLIP-60</a> contains a detailed proposal on how to reorganize the existing documentation, which can be used as a starting point.</p> |
| |
| <p><strong>2) Extend the Table API & SQL Documentation</strong></p> |
| |
| <p>Some areas of the documentation have insufficient detail or are not <a href="https://flink.apache.org/contributing/docs-style.html#general-guiding-principles">accessible</a> for new Flink users. Examples of topics and sections that require attention are: planners, built-in functions, connectors, overview and concepts sections. There is a lot of work to be done and the technical writer could choose what areas to focus on — these improvements could then be added to the documentation rework umbrella issue (<a href="https://issues.apache.org/jira/browse/FLINK-12639">FLINK-12639</a>).</p> |
| |
| <p>If you’re interested in learning more about this project idea or want to get involved in GSoD as a technical writer, check out the <a href="https://flink.apache.org/news/2020/05/04/season-of-docs.html">announcement blogpost</a>.</p> |
