------------------------------------
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.
