Github user sihuazhou commented on the issue: https://github.com/apache/flink/pull/6001 hi @medcv I think maybe it better to assign the issue to yourself before working on that, this could help to avoid depulicate works(cause i notice that you make the PRs without assigning to yourself), you can request the contribution permisson from the dev mail, i think PMCs will accpet your request once they saw your request, it always very quickly. With the permisson, you can assign the issue as you wish then. Best~
