I have created a simple minimal reproducible example that shows what I am talking about: https://github.com/DomWos/FlinkTTF/tree/sql-ttf
It contains a test that shows that even if the output is in order which is enforced by multiple sleeps, then for parallelism > 1 there is no output and for parallelism == 1, the output is produced normally. Best Regards, Dom.
