Question

Is it possible to create socket with multiple outgoing (ingoing) connections using ZeroMQExtensions?

More about multiple connections in ZeroMQ guide.

upd:
I can’t see equavalent sample with ZeroMQExtensions. In 0MQExtensions documnetation i found:

newPubSocket(socketParameters: Array[SocketOption]): ActorRef

Java API factory method to create the actor representing the ZeroMQ Publisher socket. You can pass in as many configuration options as you want and the order of the configuration options doesn’t matter They are matched on type and the first one found wins.

PS: I don’t known scala and just started reading akka documentation to understand I need Akka or not.

Answer 1

I found solution (it was not intuitive but works):

    ActorRef subSocket = ZeroMQExtension.get(getContext().system())
            .newSubSocket(null, new Listener(getSelf()), new Subscribe("health"));

    @Override
    public void preStart() {
        super.preStart();

        subSocket.tell(new Connect("tcp://127.0.0.1:1237"));
        subSocket.tell(new Connect("tcp://127.0.0.1:1238"));
    }
