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

             Summary: Allow users to specify methods instead of fields in key expressions
                 Key: FLINK-1138
                 URL: https://issues.apache.org/jira/browse/FLINK-1138
             Project: Flink
          Issue Type: Improvement
          Components: Java API
            Reporter: Robert Metzger
            Priority: Minor


Currently, users can specify grouping fields only on the fields of a POJO.
It would be nice to allow users also to name a method (such as "getVertexId()") to be called.
