Yuan Mei updated FLINK-5337:
----------------------------
Priority: Minor (was: Major)
> Introduce backwards compatible state to task assignment
> -------------------------------------------------------
>
> Key: FLINK-5337
> URL: https://issues.apache.org/jira/browse/FLINK-5337
> Project: Flink
> Issue Type: Sub-task
> Components: Runtime / State Backends
> Reporter: Stefan Richter
> Priority: Minor
> Fix For: 2.0.0
>
>
> Flink assigns state to tasks through either a) user defined uids or b) uids
> generated through hashing certain properties of the StreamingJobGraph.
> While method a) is backwards compatible, it can be tedious for the user.
> Method b) easily breaks w.r.t. backwards compatibility under any changes to
> graph generation, e.g. when removing chaining.
> We should think about a backwards compatible way assigning state to tasks,
> that hopefully works without explicit uid assignment by the user.
