Subject [ANNOUNCE] Weekly Community Update 2019/45
Date Sun, 10 Nov 2019 16:16:47 GMT
Dear community,

happy to share this week's community digest with updates on stateful
functions & Flink 1.8.3, a discussion on a connector for
Hortonworks/Cloudera's schema registry, a couple of meetups and a bit more.

Flink Development

* [stateful functions] After the successful vote to accept* Stateful
Function*s into Flink Igal has started a thread to discuss a few details of
the contribution like repository name, mailing lists, component name, etc.

* [releases] Jingcheng has started a conversation about the release of *Flink
1.8.3*. Probably still waiting for a few fixes to come in, but looks like
there could be a first RC soon. [2]

* [connectors] Őrhidi Mátyás and Gyula propose to contribute a connector
for *Hortonworks/Cloudera Schema Registry*, which can be used during
de-/serialization in Flink's Kafka Connector. [3]

* [python] Apache Flink will start Python processes to execute *Python UDFs*
in the Table API, planned for 1.10. Dian Fu has published a proposal how to
integrate the resource requirements of these Python processes into the
unified memory configuration framework, which is currently introduced in
FLIP-49. [4]


Notable Bugs

* [FLINK-14382] [1.9.1] [1.8.2] [yarn] In Flink 1.9+ filesystem
dependencies can be loaded via a plugin mechanism, each with its own
classloader. This does currently not work on YARN, where the plugin
directory is directly added to the classpath instead. [5]
