row-time deduplicate mini-batch
[ https://issues.apache.org/jira/browse/FLINK-23531?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
tartarus updated FLINK-23531:
-----------------------------
Description:
current we keep all 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
