-------------------------------------

             Summary: JobID should not be part of the registration key to the SharedStateRegistry
                 Key: FLINK-6535
                 URL: https://issues.apache.org/jira/browse/FLINK-6535
             Project: Flink
          Issue Type: Improvement
          Components: State Backends, Checkpointing
    Affects Versions: 1.3.0
            Reporter: Stefan Richter
            Assignee: Stefan Richter


Currently, the job id is part of the registration key in the {{SharedStateRegistry}}. I suggest to remove this part of the key because the job id changes after a restart. So when we do not update job ids in the registry, referencing shared state will fail for future checkpoints. When we update it, we basically replace the information. So I think there would be no value in addint this the the composite key.
