failure processing logic.A callback interface about how to fail a job.Various reasons why a checkpoint was failure.A checkpoint ID counter.A collection of simple metrics, around the triggering of a checkpoint.A builder forCheckpointMetrics.Options for performing the checkpoint.How a checkpoint should be aligned.The plan of one checkpoint, indicating which tasks to trigger, waiting for
