 Hi Rex,

I think doc [1] should have given some descriptions. Rescaling from previous checkpoint is still supported in current Flink version.

Subject: Restoring from checkpoint with different parallism
 
Hello,

When using the TableAPI, is it safe to run a flink job with a different `-p` parallelism while restoring from a checkpoint (not a savepoint) using `-s`, without any rescaling of actual machines? I don't seem to find this documented anywhere.

Thanks!
