[ANNOUNCE] Weekly community update #22

Dear community,

I know it has been quite some time but here is the weekly community update thread #22. Please post any news and updates you want to share with the community to this thread.

# Release 1.5

After a lot of work and good amount of testing, the community has finally released Apache Flink 1.5.0. The new release contains a lot of new features like a reworked deployment model, support for broadcast state, SQL CLI, full resource elasticity, faster recovery and an enhanced network stack to support higher throughput and lower latencies and many more [1].

# New committers

In the past weeks the Flink community could gain a couple of new committers. The community is proud that Xingcan Cui, Nico Kruber and Shuyi Chen are helping to stack up the committer ranks.

# On going discussions

## Enable GitBox integration for Flink's repository

In order to give the community a bit more tooling around it's Github mirror, the community decided to activate the GitBox integration [2]. That way, PR management and reviewing will hopefully be facilitated.

## Improving Flink's timer management

An effort to improve Flink's timer management has been started [3]. The goal is to make Flink timers scalable and asynchronously checkpointable.

## Adding Elastic Filter for record deduplication

The community started a discussion about adding an approximative deduplication operator based on filters (e.g. Bloom, Cuckoo, etc.) [4]. Having an approximate filter would allow to speed up certain operations.

# Flink Forward Berlin 2018 call for presentations

The call for presentations for Flink Forward Berlin 2018 [5] closes on June 4, 11:59 PM CEST. So if you have an interesting topic to share with the community, then please submit a proposal.
