Hi Fanbin If you do not change the parallelism or add and remove operators, you could still use savepoint to resume your jobs with Flink SQL.
However, as far as I know, Flink SQL might not configure the uid currently and I’m pretty sure blink branch contains this part of setting uid to stream node.

How do we do this for Flink SQL? According to https://stackoverflow.com/questions/55464955/how-to-add-uid-to-operator-in-flink-table-api, it is not possible. Does that mean, I can't use savepoint to restart my program if I use Flink SQL? Thanks, Fanbin
