[jira] [Closed] (FLINK-8569) Provide a hook to override the default KeyGroupRangeAssignment

     [ https://issues.apache.org/jira/browse/FLINK-8569?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

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.

> 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.
