Ok, thanks for the clarification.    Sent from Mail for Windows   From: Francis Conroy Sent: Tuesday, April 26, 2022 7:26 AM To: lan tran Cc: user@flink.apache.org Subject: Re: UUID on TableAPI   Hi Quynh,    My understanding is mostly based on the documentation I linked in the first reply. If the flink version and the query both remain the same then you can restart a job from a savepoint, this means that it might be workable for running a low-criticality job on say an AWS spot instance. That's about all I know.   On Tue, 26 Apr 2022 at 10:17, lan tran <indigoblue7...@gmail.com> wrote: Hi Francis, Thanks for the reply. However, can you elaborate more on the part ‘work for cases where you wish to pause/resume a job’ ? Is there another way besides savepoint having this mechanism that can implement in Table API ?

Is that what you mean? The savepoint UUIDs are issued dynamically when you request them, flink won't know automatically what the last savepoint was, but you can start a new job and restore from a savepoint by passing in the UUID. All that said there are limitations around using savepoints and Flink SQL because of the way the planner works https://nightlies.apache.org/flink/flink-docs-release-1.14/docs/dev/table/concepts/overview/#stateful-upgrades-and-evolution. However it might work for cases where you wish to pause/resume a job.   On Fri, 22 Apr 2022 at 13:54, lan tran <indigoblue7...@gmail.com> wrote: Hi team, Currently, I want to use savepoints in Flink. However, one of the things that I concern is that is there any way we can set the UUID while using Table API (SQL API) ? If not, does it has any mechanism to know that when we start the Flink again, it will know that it was that UUID ?
