[ANNOUNCE] Weekly Community Update 2019/41

[Konstantin Knauf-3]

Dear community,

happy to share a small community update this week with Flink Forward
Europe, "Stateful Functions" and a bit more.

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

* [api] Stephan proposes to contribute* Stateful Function (statefun.io
<http://statefun.io>)* to Apache Flink. Stateful Functions were announced
by Ververica earlier this week at Flink Forward Europe. It is an Actor-like
API, which makes it easier to to write general purpose event-driven
application on top of Flink. There has been a lot of positive feedback so
far. [1]

* [releases] The vote/verification of *Flink 1.9.1 RC1* is still ongoing.
[2]

* [python] Dian Fu started a discussion to *drop Python 2 support* in Flink
1.10. It looks like there is a consensus for this due to Python 2's EOL in
January 2020 and additional external dependencies (e.g. Beam) added for the
the 1.10 release increasing the burden of continued  support.  [3]

* [config] In a previous update, I covered FLIP-54 "Evolve ConfigOption and
Configuration". In the course of the discussion this FLIP has turned out to
be intertwined with too many other areas and ongoing developments. Hence,
Timo proposed to split it up into three FLIPS. The first of these is *FLIP-77
"Introduce ConfigOptions with Data Types"*. It proposes add information
about the described type to ConfigOptions. [4]

* [checkpointing] Biao Liu has started a survey about the usage of the "
*ExternallyInducedSource*" and "*WithMasterCheckpoint*" interfaces. He is
currently working on these and is looking for feedback from existing users.
