Akka ask Broadcast

Question

I have an akka 2.0 round-robin router. Now I need to broadcast a message to all routees and await the answers from all of them. I did not found a way to do so yet. First I had a list of actors that I passed to the router, but now I need to load them from my application.conf. Is there a way to await all messages of a Broadcast? It would be fine as well if I could get the number of routees from the conf flie.

Answer 1

If you know the number of routees, then you would normally just count the number of answers received. However, you may want to account for a timeout, especially if your actors are running distributed because there is no guarantee that messages really get delivered.
