[ANNOUNCE] Weekly Community Update 2020/18

[Konstantin Knauf-4]

Dear community,

happy to share - a brief - community update this week with an update on
Flink 1.10.1, our application to Google Season of Docs 2020, a discussion
to support Hadoop 3, a recap of Flink Forward Virtual 2020 and a bit more.

Flink Development
==============

* [releases] Yu has published a RC #2 for Flink 1.10.1. No -1s so far. [1]

* [docs] Apache Flink's application to Google Season of Docs 2020 is about
to be finalized. Marta has opened PR for the announcement and Seth &
Aljoscha volunteered as Mentor. Apache Flink is pitching a project to
improve the documentation of Table API & SQL. [2]

* [hadoop] Robert has started a discussion on adding support for Hadoop 3.
In particular, the thread discusses the questions of whether Hadoop 3 would
be supported via flink-shaded-hadoop or not. [3]

* [configuration] Timo has started a discussion on how we represent
configuration hierarchies in properties (Flink configuration as well as
Connector properties), so that the resulting files would be valid
JSON/YAML. [4]

* [connectors] Leonard Xu proposes to refactor package, module and class
names of the Flink JDBC connector to be consistent with other connectors .
Details in the [5].

flink-packages.org
==============

* Alibaba has published a preview version of its SpillableHeapStateBackend
on flink-packages.org. [6] This statebackend is contributed to Apache in
FLINK-12692 [7]. The SpillableHeapStateBackend is a Java Heap-based
Statebackend (like the FilesystemStatebackend) that spills the coldest
state to disk before the heap is exhausted.

[7] https://issues.apache.org/jira/browse/FLINK-12692
