> When the new checkpoint is completed, an old checkpoint will be deleted by
> calling CompletedCheckpoint.discardOnSubsume().
> When deleting old checkpoints, follow these steps:
> 1, drop the metadata
> 2, discard private state objects
> 3, discard location as a whole
> In some cases, is it possible to delete the checkpoint folder recursively by
> one call?
> As far as I know the full amount of checkpoint, it should be possible to
> delete the folder directly.
