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

             Summary: Add ReducePartial and GroupReducePartial Operators
                 Key: FLINK-1622
                 URL: https://issues.apache.org/jira/browse/FLINK-1622
             Project: Flink
          Issue Type: Improvement
    Affects Versions: 0.9
            Reporter: Aljoscha Krettek


This does what a Reduce or GroupReduce Operator does, except it is only performed on a local partition.

This is also similar to an explicit combine that can output a type that is different from the input.
