---------------------------------
Summary: Do not add mini-batch assigner operator if it is useless
Key: FLINK-32622
URL: https://issues.apache.org/jira/browse/FLINK-32622
Project: Flink
Issue Type: Improvement
Components: Table SQL / Planner
Affects Versions: 1.19.0
Reporter: Fang Yong
Currently if user config mini-batch for their sql jobs, flink will always add
mini-batch assigner operator in job plan even there's no agg/join operators in
the job. Mini-batch operator will generate useless event and cause performance
issue for them. If the mini-batch is useless for the specific jobs, flink
should not add mini-batch assigner even when users turn on mini-batch
mechanism.
