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