@Zhanghao Chen: I am not completely sure at this point what this will mean for 2.0 simply because I am also not sure what that will mean for the operator as well :) I think this will depend on the compatibility guarantees we can provide across Flink major versions in general. We have to look into that and tackle the question there independently.
