Hi, I recently read there is a Netty single channel between nodes to strongly guarantee message ordering, is that true?
My other concern is about message ordering when using remote/cluster extensions: Say there are N channels between *node_1* and *node_2*: - How is a channel selected when I send a message from *actor_A@node_1* to *actor_B@node_2*, is the channel always the same on *node_1* to guarantee the ordering for that pair? I'm assuming yes, making this question to lead to a more complex question. - Lets now say that I have a round-robin local router which created *actor_1..N@node_1, N = CPUs* and messages are processed on each copy actor of that router, how is a channel selected if each of these actors say *actor_B.tell(message, noSender())*? but what I'm trying to figure out is if that set of actors use the same channel making* noSender()* create a contention side effect? If *noSender()* has a bad side effect it should be said on the documentation, it could be that it is treated as something special and then from the context the real sender is used to identify what channel it is going to be used. Now if there is only a Netty channel to guarantee message ordering, why not pick the channel base on the hash of the pair composed by sender and recipient? That will still guarantee the message ordering that is officially documented and reduce contention considerably IMHO.
