No. The default max parallelism of 128 will be applied. If you try to
restore above that value, the restore will fail and you can simply restore
at a smaller value.
No data loss.

Thanks for your replay. If we don't set the max parallelism, and we change the
parallelism to a very big num, will the state loss?

Hi Yang,
Flink keeps the max key groups the same no matter how parallelism changes, and
use this to avoid state data lost [1]

Hi,
to rescale, you should take a savepoint, stop the job, then restart from
the savepoint with your new desired parallelism. This way, no data will be
lost.
