[ANNOUNCE] Weekly Community Update 2019/48

[Konstantin Knauf-3]

Dear community,

happy to share a short community update this week. With one week to go to
the planned feature freeze for Flink 1.10 and Flink Forward Asia in Beijing
the dev@ mailing list pretty quiet these days.

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

* [releases] Hequn has started the vote on RC1 for Flink 1.8.3, which
unfortunately has already received a -1 due to wrong/missing license
information. Expecting a new RC soon. [1]

* [sql] In the past timestamp fields in Flink SQL were internally
represented as longs and it was recommended to use longs directly in
user-defined functions. With the introduction of a new TimestampType the
situation has changed and conversion between long and TIMESTAMP will be
disabled. [2]

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

* [FLINK-14930] [1.9.1] The OSS filesystem did not allow the configuration
of additional credentials providers due to a shading-related bug. Resolved
for 1.9.2. [3]

Events, Blog Posts, Misc
===================

* Flink Forward Asia took place this week at the National Congress Center
in Beijing organized by Alibaba. Talks by Ververica, Tencent, Baidu,
Alibaba, Dell, Lyft, Netflix, Cloudera and many other members of the
Chinese Apache Flink community, and more than 1500 attendees as far as I
heard. Impressive! [4]

* At Flink Forward Asia Alibaba announced it has open sourced Alink, a
machine learning library on top of Apache Flink[5,6]

* Upcoming Meetups
    * The first meetup of the Apache Flink Meetup Chicago on 5th of
December comes with four talks(!) highlighting different deployment methods
of Apache Flink (AWS EMR, AWS Kinesis Analytics, Verveirca Platform, IBM
Kubernetes). Talks by *Trevor Grant*, *Seth Wiesman*, *Joe Olson* and
*Margarita
Uk*. [7]
    * On December 17th there will be the second Apache Flink meetup in
Seoul. Maybe Dongwon can share the list of speakers in this thread, my
Korean is a bit rusty. [8]
