Stephan Ewen commented on FLINK-2737:
-------------------------------------
Currently, the {{KeyedDataStream}} offers all functions from the {{DataStream}}.
I would suggest to restrict the functions to:
- The typical unary element-at-a-time functions ( map(), flatMap(), filter(),
... )
- window
- Future: joinWith()
- Future: order()
As per:
https://cwiki.apache.org/confluence/display/FLINK/Streams+and+Operations+on+Streams
> KeyedDataStream should not be a subclass of DataStream
