---------------------------------------------

             Summary: Reuse single FileSegmentCheckpointStateOutputStream for multiple checkpoints
                 Key: FLINK-11941
                 URL: https://issues.apache.org/jira/browse/FLINK-11941
             Project: Flink
          Issue Type: Sub-task
          Components: Runtime / Checkpointing
            Reporter: Congxian Qiu(klion26)
            Assignee: Congxian Qiu(klion26)


After the previous first sub-tasks have been resolved, we'll solve the small file problems by writing all states of one checkpoint into a single physical file. In this sub-task, we'll try to share the underlying physical file across multiple checkpoints.

This is configurable and disabled for default.
