[jira] [Created] (FLINK-7008) Update NFA state only when the NFA changes.

Kostas Kloudas created FLINK-7008:
-------------------------------------

             Summary: Update NFA state only when the NFA changes.
                 Key: FLINK-7008
                 URL: https://issues.apache.org/jira/browse/FLINK-7008
             Project: Flink
          Issue Type: Improvement
          Components: CEP
    Affects Versions: 1.3.1
            Reporter: Kostas Kloudas
             Fix For: 1.4.0


Currently in the {{AbstractKeyedCEPPatternOperator.updateNFA()}} method we update the NFA state every time the NFA is touched. This leads to redundant puts/gets to the state when there are no changes to the NFA itself.
