-----------------------------------

             Summary: Make printing sinks non-parallel
                 Key: FLINK-5338
                 URL: https://issues.apache.org/jira/browse/FLINK-5338
             Project: Flink
          Issue Type: Sub-task
          Components: Streaming
            Reporter: Stephan Ewen
            Priority: Minor
             Fix For: 2.0.0


This is a suggestion, up for discussion.

I suggest to make the {{DataStream::pring()}} 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.
