Hi! I am sort of new to Akka. I am implementing DDD around clustered actors. Since they are clustered I need to make sure they receive the messages at least once. Because of that I have an implicit actor in a Play controller which calls my target actor the aggregate passing through a "proxy" Actor which implements AtLeastOnceDelivery. So this looks like: A -> B -> C, and C replies with an ACK confirm to B. In that precise moment I need to reply to A the response so it is the other way around: C -> B -> A. But given the context when B received the ACK from C, the sender is B and not A... so I kind of handled this by keeping the A actor path in the event messages so I can get A actorRef at anytime inside B and reply to the temporary actor which fulfills the Ask future in Play controller. Is this a common practice to keep an Actor path within the context of Messages to be able to get a Sender from a path? Another question I have and I have not seen any sample about is how to treat with all the AtLeastOnceDelivery failure messages such as " UnconfirmedWarning" and how that maps to the Play controller to feedback the rest api clients? Would love to see some code sample.
Thanks, Sebastian. -- >>>>>>>>>> Read the docs: http://akka.io/docs/ >>>>>>>>>> Check the FAQ: >>>>>>>>>> http://doc.akka.io/docs/akka/current/additional/faq.html >>>>>>>>>> Search the archives: https://groups.google.com/group/akka-user --- You received this message because you are subscribed to the Google Groups "Akka User List" group.
