---------------------------------
Summary: Add interface for grouped policies to broadcast
information to other groups
Key: FLINK-1773
URL: https://issues.apache.org/jira/browse/FLINK-1773
Project: Flink
Issue Type: New Feature
Reporter: Gyula Fora
Priority: Minor
The current windowing does not allow grouped policies to broadcast information
to each other. Adding this would allow closing windows earlier than the next
element arrives for the same group. This makes nice use cases possible like
detecting user sessions on data streams.
