Jingsong Lee created BEAM-1588:
----------------------------------

             Summary: Reuse StateNamespace.stringKey in Flink States
                 Key: BEAM-1588
                 URL: https://issues.apache.org/jira/browse/BEAM-1588
             Project: Beam
          Issue Type: Improvement
          Components: runner-flink
            Reporter: Jingsong Lee
            Assignee: Jingsong Lee


See BEAM-1587
StateNamespace.stringKey did two things: the base64 encoding of window , and then String.format.
These two things consumption is not small. We can cache it in State and reuse.
Further more, we can cache the state.
