>                 URL: https://issues.apache.org/jira/browse/FLINK-4322
>             Project: Flink
>          Issue Type: Improvement
>          Components: State Backends, Checkpointing
>    Affects Versions: 1.1.0
>            Reporter: Stephan Ewen
>            Assignee: Stephan Ewen
>             Fix For: 1.2.0
> The Checkpoint coordinator should have the functionality of both handling checkpoints
and savepoints.
> The difference between checkpoints and savepoints is minimal:
>   - savepoints always write the root metadata of the checkpoint
>   - savepoints are always full (never incremental)
> The commonalities are large
>   - jobs should be able to resume from checkpoint or savepoints
>   - jobs should fall back to the latest checkpoint or savepoint
> This subsumes issue https://issues.apache.org/jira/browse/FLINK-3397
