[ANNOUNCE] Weekly Community Update 2020/02

[Konstantin Knauf-3]

Dear community,

happy new year from my side, too, and thanks a lot to Hequn for helping out
with the weekly updates during the last three weeks! I enjoyed reading
these myself for a change.

This week's community digest features an update on Flink 1.10 release
testing, a proposal for a SQL catalog to read the schema of relational
databases and the Call for Presentations of Flink Forward San Francisco.

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

* [releases] The community is still testing and fixing bugs for* Flink 1.10*.
You can follow the effort on the release burndown board [1]. Should not be
too long until a first RC is ready.

* [sql] Bowen proposes to add a *JDBC and Postgres Catalog *to the Table
API. By this, Flink could automatically create tables corresponding to the
tables in relational databases. Currently, users need to manually create
corresponding tables (incl. schema) on the Flink-side. [2,3]

* [configuration] Xintong proposes to change some of the default values for
Flink's memory configuration following his work on *FLIP-49 *and is looking
for feedback [4]

* [datastream api] Congxian proposes to unify the handling of adding "null"
values to *AppendingState* across statebackends. The proposed behavior is
to make all statebackends refuse "null" values. [5]

Notable Bugs
==========

A lot of activity due to release testing, but I did not catch any new
notable bugs for already released versions.
