Kurt Ostfeld commented on FLINK-3154:
-------------------------------------

The PR is ready: [https://github.com/apache/flink/pull/25896]

This is based on the Flink 2.0 master branch as of a few days ago. This passes 
all CI tests. There are no merge conflicts as of this moment.

This is a simpler PR, as it doesn't need compatibility with existing saved 
Flink 1.x state as Flink 2.0 isn't providing that.

If there is review feedback or requested changes, I can address those. 
Otherwise, this should be ready to merge.

> Flink's Kryo version is outdated and could be updated to a newer version, 
> e.g. kryo-3.0.3.
> From ML: we cannot bumping the Kryo version easily - the serialization format 
> changed (that's why they have a new major version), which would render all 
> Flink savepoints and checkpoints incompatible.
