Hi all, I want to implement a join operator which can use different strategies for joining tuples. I saw that with CoProcessFunction I am able to implement low-level joins . However, I do know how to decide between different algorithms to join my tuples.
On the other hand, to do a broadcast join I will need to use the broadcast operator  which yields a BroadcastStream. Therefore, I am not sure if I will need to implement my own operator to do this or if it is still possible to do with CoProcessFunction. Does anyone have some clues for this matter?
