Akka.Net: What is the best method for communicating between two or more independent clusters?


Akka.Net: What is the best method for communicating between two or more independent clusters?

Hope this helps Usually your cluster consists of multiple actor systems. However in Akka.NET clusters can be heterogeneous, which means that nodes (actor systems) may differ from each other in terms of performed operations and loaded assemblies. To differentiate them in this regard, you can configure each actor system with different set of roles.
Cluster roles can also be used to limit the communication between nodes when updating the code inside the cluster - so that nodes with the older code won't try to talk with the updated ones. This allows to perform incremental update of the cluster without shutting it down.

I hope this helps . converting a "question edit" to an answer
Found an interesting development going of not yet officially released AKKA API:
code :
val listener = actorOf(new Actor {
  def receive: Receive = {
    case message: ZMQMessage => ...
    case _ => ...
  }
}).start

val socket = ZMQ.newSocket(SocketParameters(context, SocketType.Sub, Some(listener)))
socket ! Connect("tcp://127.0.0.1:1234")
socket ! Subscribe(Seq())

Hope that helps There is few possible solutions. First, you want to read if DarthVader is in NoOp mode from config then actor is created (Typesafe Config will work fine).
code :
Config vader = conf.getConfig("vader");
bool isNoOpMode = vader.getBoolean("state");
Timeout timeout = new Timeout(Duration.create(5, "seconds"));
Future<Object> future = Patterns.ask(lordVader, statusReportMsg, timeout);
final ExecutionContext ec = system.dispatcher();

future.onComplete(new OnComplete<VaderResponse>() {
  public void onComplete(Throwable failure, VaderResponse result) {
    if (failure != null) {
      // Derp
    } else {
      // Report acknowledged
    }
  }
}, ec);

I wish did fix the issue.
if there's only one FizzBuzz (which there is) non-actor/driver, and ten thousand ChickenCluckDetector actors
code :
public class ChickenCluckMaster extends UntypedActor {

    private FizzBuzz fizzBuzz;

    public ChickenCluckMaster(FizzBuzz fizzBuzz) {
        this.fizzBuzz = fizzBuzz;
    }

    public void onReceive(Object message) throws Exception {
        if (message instanceOf CreateDetector) {
            getContext().actorOf(
                Props.create(ChickenCluckDetector.class, getSelf); // Create child
        } else if (message instanceof Cluck) {
            fizzBuzz.onCluck(cluck);
        } else {
            unhandled(message);
        }
    }

}

public class ChickenCluckDetector extends UntypedActor {

    private ActorRef master;

    public ChickenCluckDetector(ActorRef master) {
        this.master = master;
    }

    public void onReceive(Object message) throws Exception { 
        if (message instanceof Cluck) {
            Cluck cluck = (Cluck) message;
            master.tell(cluck, getSelf);
        } else {
            unhandled(message);
        }
    }

}

should help you out You should use protobuf.
Protobuf is only a way Mesos defines its API. Mesos can handle binary serialized protobuf requests or JSONs. Mesos uses protobuf in version 2 (there will be an upgrade to 3) and there is no standard serialization from protobuf v2 to JSON and Mesos does not fully support v3 JSON mapping, see MESOS-5995. In theory you can create JSON manually but using protobuf guarantee you will use proper version of API and handle serialization for you.
