      Description

      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
