[jira] [Created] (FLINK-5043) Converting keyed state from Flink 1.1 backend implementations to their new counterparts in 1.2

Stefan Richter created FLINK-5043:
-------------------------------------

             Summary: Converting keyed state from Flink 1.1 backend implementations to their new counterparts in 1.2
                 Key: FLINK-5043
                 URL: https://issues.apache.org/jira/browse/FLINK-5043
             Project: Flink
          Issue Type: Sub-task
          Components: State Backends, Checkpointing
    Affects Versions: 1.2.0
            Reporter: Stefan Richter
            Assignee: Stefan Richter


Keyed state backends became keygroup aware in Flink 1.2 and their hierarchy as a whole changed significantly. We need to implement a conversion so that old snapshots can be restored into new backends.
