Stephan Ewen resolved FLINK-1138.
---------------------------------
    Resolution: Won't Fix

Not crucial, and more complex than anticipated

> 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.
