I just read about reliable proxies in akka, but I couldn't find a way to use them with typed actors. What would be the best way to achieve that?
The Reliable Proxy Pattern is a way to manage the quality of service when sending from one actor to another. TypedActors are not made for this use case, their use is rather limited as I previously described. So the answer is: if you want to explore messaging patterns, use normal (untyped) actors, because only they really model the message passing nature of the actor model.
