Summary: Allow skip everytime change log for row-time deduplicate
mini-batch
Key: FLINK-23531
URL: https://issues.apache.org/jira/browse/FLINK-23531
Project: Flink
Issue Type: Improvement
Components: Table SQL / Runtime
Reporter: tartarus
current we keep everytime change log for row-time deduplicate mini-batch,
we need buffer all record on heap.
In some cases, users do not need all change logs;
In this way, the memory pressure and the calculation pressure of downstream
operators can be reduced
