> The operator coordinators are stateful and hence need to store state in checkpoints.
> See FLIP-27 for details on operator coordinators: https://cwiki.apache.org/confluence/display/FLINK/FLIP-27%3A+Refactor+Source+Interface
> The initial implementation approach is to trigger coordinator checkpoints first, and when all coordinator checkpoints are done, then the source checkpoint barriers will be injected.
> _Note:_ This functionality will eventually replace the checkpoint master hooks.
