-------------------------------------
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.
