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

             Summary: Remove magic number in key and namespace serialization
                 Key: FLINK-5606
                 URL: https://issues.apache.org/jira/browse/FLINK-5606
             Project: Flink
          Issue Type: Improvement
          Components: Queryable State
            Reporter: Ufuk Celebi
            Assignee: Ufuk Celebi
            Priority: Minor


The serialized key and namespace for state queries contains a magic number between the key and namespace: {{key|42|namespace}}. This was for historical reasons in order to skip deserialization of the key and namespace for our old {{RocksDBStateBackend}} which used the same format. This has now been superseded by the keygroup aware state backends and there is no point in doing this.
