-----------------------------------
Summary: Unify CheckpointCoordinator and SavepointCoordinator
Key: FLINK-4322
URL: https://issues.apache.org/jira/browse/FLINK-4322
Project: Flink
Issue Type: Bug
Components: State Backends, Checkpointing
Affects Versions: 1.1.0
Reporter: 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
