godfrey he updated FLINK-19822:
-------------------------------
Description:
This is similar
[FLINK-12575|https://issues.apache.org/jira/browse/FLINK-12575], we could
implement {{satisfyTraits}} method for stream nodes to remove redundant
shuffle. This could add more possibilities that more operator could be merged
into multiple input operator.
Note: This feature should only be enabled only when multiple input operator is
enabled because currently key selector is applied only at the header of the
chain.
