Github user uce commented on the issue: https://github.com/apache/flink/pull/5102 I would be in favour of removing this or moving it to Bahir, but it is currently used in a [doc example](https://ci.apache.org/projects/flink/flink-docs-release-1.4/quickstart/run_example_quickstart.html). Besides that I doubt that this is of much value to users. If you think it's OK with it, let's merge this for now and think about the example thing really needs it.
