Hi,

Yes, you can change the parallelism. One thing that you can not change is “max parallelism”.

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.
