Hi folks, I would like to know the difference between externalized checkpoint and savepoint. Regarding externalized checkpoint, is the checkpoint written to persistent storage only if the job is failed or suspended? What about cancelled or killed by the user? What information is written to persistent storage when externalzed checkpoint is created? How is it different when compared to savepoint? Consider this scenario, I have killed a flink job and would like to restart the job while restoring previous state. I have both options – restore from latest checkpoint and savepoint. Which should one choose for job restore and why?
