[jira] [Created] (FLINK-15526) Add RollingPolicy to PartitionWriters

Jingsong Lee created FLINK-15526:
------------------------------------

             Summary: Add RollingPolicy to PartitionWriters
                 Key: FLINK-15526
                 URL: https://issues.apache.org/jira/browse/FLINK-15526
             Project: Flink
          Issue Type: Sub-task
          Components: Table SQL / Runtime
            Reporter: Jingsong Lee
             Fix For: 1.11.0


Now our partition writers will write a whole file in a checkpoint if there is no partition change.

Sometimes this file is too big, it is better to add a RollingPolicy for controlling file size.

We can just add policy controlled by file size and record number.
