Cancel the flink task and restore from checkpoint ,can I change the flink operator's parallelism

[LakeShen]

Hi community,
      I have a question is that I cancel the flink task and retain the
checkpoint dir, then restore from the checkpoint dir ,can I change the
flink operator's parallelism,in my thoughts, I think I can't change the
flink operator's parallelism,but I am not sure.
     Thanks to your reply.

Best wishes,
LakeShen

I think you can modify the operator’s parallelism. It is only if you have
set maxParallelism, and while restoring from a checkpoint, you shouldn’t
modify the maxParallelism. Otherwise, I believe the state will be lost.
