Till Rohrmann closed FLINK-8569.
--------------------------------
Resolution: Won't Do
Making the key group partitioning configurable will have wide reaching
consequences for savepoints. I believe that we don't have the capacities for
such a change at the moment.
> Provide a hook to override the default KeyGroupRangeAssignment

> Key: FLINK-8569
> URL: https://issues.apache.org/jira/browse/FLINK-8569
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Coordination
> Reporter: Nagarjun Guraja
> Priority: Major
>
> Currently the class 'org.apache.flink.runtime.state.KeyGroupRangeAssignment'
> has static methods(not pluggable) which is a little prohibitive and
> unintuitive to onboard some of the keyed embarrassingly parallel jobs. It
> would be helpful if a hook per job is provided to make this pluggable.
