> This is a suggestion, up for discussion.
> I suggest to make the {{DataStream::print()}} sink function inherently non-parallel, i.e., always executed in a single parallel sink.
> Since printing is only for toy setups anyways, and the performance is usually bound by the stdout stream, non-parallel prints should be sufficient.
