-----------------------------------
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.
