Github user StefanRRichter commented on the issue: https://github.com/apache/flink/pull/6302 @indrc I think there is no contradiction between Stephan's comment and my suggestion about 1. I stand by my point that this is a very common task and there is no very special requirement in the random string that would really require a new method. My initial suggestions `RandomStringUtils` and Flink's `UUID` are both already available without adding another dependency and a full-test search for `randomstring` in the project also gave some hits like e.g. `StringUtil`, that could also be used or extended in a more general way than putting our own algorithm in this particular place.
