Hi All, A bit unusual FLIP [1], as this is a bug fix for a problem that I have recently discovered [2]. However I think FLIP is required, as properly fixing the issue requires changes to the public API.
As this is a bug fix, I would propose to back-port this change to previous releases (1.19 and 1.20), despite this changing Public API. Best, Piotrek [1] https://cwiki.apache.org/confluence/x/oQvOEg [2] https://issues.apache.org/jira/browse/FLINK-35886
