[ANNOUNCE] Weekly Community Update 2020/25

[Konstantin Knauf-4]

Dear community,

happy to share this week's community update: release testing for Flink
1.11.0 is slowly converging, and the first feature discussions for the
upcoming release cycle are coming up.

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

* [releases] The community has published another non-voting release
candidate for Flink 1.11.0 to facilitate further release testing. [1]

* [connectors] Jacky Lau proposes to drop support for ElesaticSearch 5.x to
facilitate the implementation of FLIP-127, a source connector for
ElasticsSearch. [2]

* [connectors] Gyula proposes to upgrade the HBase connector to 2.2.x. and
dropping support for 1.4.x. The discussion indicates that there are still a
lot of HBase 1.x installations out there and hence there are reservations
on dropping support for it now. [3]

* [docs] Flink Master has been re-renamed to Jobmanager as part of a larger
discussion about the usage of the terms slave/master in Apache Flink. [4,5]

* [sql] Fabian has started a discussion on a SQL syntax for a Table API's
StatementSet. A StatementSet allows users to group multiple INSERT INTO
statements, so that they are compiled into a single Flink job. This
functionality has been added in FLIP-84, but is not exposed in SQL yet. [6]

* [sql] Jingsong Li has started a discussion on how to ensure that new SQL
features are also supported by the Flink SQL client going forward. So far,
new features are often only available in the Flink SQL client with a delay
as developers forget to explicitly add support for them directly. [7]
