Anton Solovev updated FLINK-5338:
---------------------------------
Description:
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.
