Subject [jira] [Created] (FLINK-4754) Make number of retained checkpoints user configurable
Date Thu, 06 Oct 2016 12:03:20 GMT
Ufuk Celebi created FLINK-4754:
----------------------------------

             Summary: Make number of retained checkpoints user configurable
                 Key: FLINK-4754
                 URL: https://issues.apache.org/jira/browse/FLINK-4754
             Project: Flink
          Issue Type: Improvement
          Components: State Backends, Checkpointing
    Affects Versions: 1.1.2
            Reporter: Ufuk Celebi


The number of retained successful checkpoints is fixed to 1. Expose this setting via the {{CheckpointConfig}}
instead of having it fixed as a static field in the {{CheckpointRecoveryFactory}}.

With the current state of things, this would require to set this value lazily in the checkpoint
store implementations instead of setting it when creating the store.
