Stephan Ewen created FLINK-5800:
-----------------------------------

             Summary: Make sure that the CheckpointStreamFactory is instantiated once per operator only
                 Key: FLINK-5800
                 URL: https://issues.apache.org/jira/browse/FLINK-5800
             Project: Flink
          Issue Type: Improvement
          Components: State Backends, Checkpointing
    Affects Versions: 1.2.0
            Reporter: Stephan Ewen
            Assignee: Stephan Ewen
             Fix For: 1.3.0, 1.2.1


Previously, the {{CheckpointSteamFactory}} was created once per checkpoint, and its repeated initialization logic (like ensuring existence of the parent directory) caused unnecessary load on some file systems at very large scale.
