[jira] [Created] (FLINK-6239) Sharing of State Across Operators

Elias Levy created FLINK-6239:

             Summary: Sharing of State Across Operators
                 Key: FLINK-6239
                 URL: https://issues.apache.org/jira/browse/FLINK-6239
             Project: Flink
          Issue Type: Improvement
          Components: Streaming
    Affects Versions: 1.1.4
            Reporter: Elias Levy


Currently state cannot be shared across operators.  On a keyed stream, the state is implicitly keyed by the operator id, in addition to the stream key.  This can make it more difficult and inefficient to implement complex topologies, where multiple operator may need to access the same state.  It would be value to be able to access keyed value and map stated across operators.
