<p>The user provided hash is an alternative to the generated hashes, that is considered when
identifying an operator through the default hash mechanics fails (e.g. because of changes
between Flink versions).
<p><strong>Important</strong>: this should be used as a workaround or for trouble shooting.
The provided hash needs to be unique per transformation and job. Otherwise, job submission
will fail. Furthermore, you cannot assign user-specified hash to intermediate nodes in an
operator chain and trying so will let your job fail.
<p>A use case for this is in migration between Flink versions or changing the jobs in a way
that changes the automatically generated hashes. In this case, providing the previous hashes
directly through this method (e.g. obtained from old logs) can help to reestablish a lost
mapping from states to their target operator.

client connection is closed before the iterator is fully drained, then the remaining buffers

If an app ID is provided, only callers who've authenticated with the given app ID will be
