Date Mon, 18 Jul 2016 15:50:20 GMT
Greg Hogan created FLINK-4231:
---------------------------------

             Summary: Switch DistinctOperator from GroupReduceFunction to ReduceFunction
                 Key: FLINK-4231
                 URL: https://issues.apache.org/jira/browse/FLINK-4231
             Project: Flink
          Issue Type: Improvement
          Components: Java API
    Affects Versions: 1.1.0
            Reporter: Greg Hogan
            Assignee: Greg Hogan


As discussed in FLINK-3279, rewriting {{DistinctOperator}} to a {{ReduceFunction}} rather
than the current {{GroupReduceFunction}} allows the user to set the {{CombineHint}} and choose
a hash-based, sort-based, or no combiner.
