Hi, [~fhueske] do you meant that we need call {{uid/setUidHash}} when we translate to DataStream? And we provided unique UID for per transformation and job.If so, we need to consider all the Operators which are in the {{table.scala}}. right?

> At the moment, the Table API does not assign UIDs and the max parallelism to operators (except for operators with parallelism 1).
> We should do that to avoid problems when rescaling or restarting jobs from savepoints.
