Aitozi commented on FLINK-31296: -------------------------------- But this will affect the join key pair in the Join operator which may affect the state compatibility, I'm not sure how to handle this implicit breaking > Add JoinConditionEqualityTransferRule to stream optimizer > --------------------------------------------------------- > > Key: FLINK-31296 > URL: https://issues.apache.org/jira/browse/FLINK-31296 > Project: Flink > Issue Type: Improvement > Components: Table SQL / Planner > Reporter: Aitozi > Priority: Major > > I find that {{JoinConditionEqualityTransferRule}} is a common rule for batch > and stream mode. So it should be added to the stream optimizer which will > bring performance improvement in some case. > Maybe, other rules also need to be reviewed whether can be aligned in batch > and stream case. -- This message was sent by Atlassian Jira (v8.20.10#820010)
