-------------------------------------

             Summary: Introduce AbortCheckpoint message from JM to TMs
                 Key: FLINK-9375
                 URL: https://issues.apache.org/jira/browse/FLINK-9375
             Project: Flink
          Issue Type: Improvement
          Components: State Backends, Checkpointing
            Reporter: Stefan Richter


We should introduce an {{AbortCheckpoint}} message that a jobmanager can send to taskmanagers if a checkpoint is canceled so that the operators can eagerly stop their alignment phase and continue to normal processing. This can reduce some backpressure issues in the context of canceled and restarted checkpoints.
