-------------------------------------
Summary: Support join/cogroup in BroadcastUtils.withBroadcastStream
Key: FLINK-31160
URL: https://issues.apache.org/jira/browse/FLINK-31160
Project: Flink
Issue Type: Improvement
Components: Library / Machine Learning
Affects Versions: ml-2.1.0, ml-2.0.0, ml-2.2.0
Reporter: Zhipeng Zhang
Fix For: ml-2.2.0
Currently BroadcastUtils#withBroadcastStream does not support cogroup/join,
since we restricted that users can only introduce one extra operator in the
specified lambda function.
To support using join/cogroup in BroadcastUtils#withBroadcastStream, we would
like to relax the restriction such that users can introduce more than more
extra operator, but only the output operator can access the broadcast variables.
