@tony810430 I am adding small followups. Most notably, I renamed the config
parameter to `state.checkpoints.num-retained`. In my experience, shorter
parameter names are better (less typos, easier to remember for users, etc...)
Please comment if you have objections.

> 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
> Assignee: Wei-Che Wei
>
> 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.
