Hi, AFAIK, the difference between a BroadcastStream and a normal DataStream is that the BroadcastStream is with a BroadcastState, but it seems that the functionality of BroadcastState can also be achieved by MapState in a CoMapFunction or something since the control stream is still broadcasted without being turned into BroadcastStream. So, I’m wondering what’s the advantage of using BroadcastState? Thanks a lot!
