I am using Akka Distributed Pub/Sub and have a single publisher and a
subscriber. My publisher is way faster than the subscriber. Is there a way
to slow down the Publisher after a certain point.
Publisher Code
public class Publisher extends AbstractActor{
private ActorRef mediator;
static public Props props() {
return Props.create(Publisher.class, () -> new Publisher());
}
public Publisher () {
this.mediator = DistributedPubSub.get(getContext().system()).mediator();
this.self().tell(0, ActorRef.noSender());
}
@Override
public Receive createReceive() {
return receiveBuilder()
.match(Integer.class, msg -> {
// Sending message to Subscriber
mediator.tell(new
DistributedPubSubMediator.Send("/user/"+Subscriber.class.getName(),
msg.toString(),
false), getSelf());
getSelf().tell(++msg, ActorRef.noSender());
})
.build();
}
}
Subscriber Code
public class Subscriber extends AbstractActor{
static public Props props() {
return Props.create(Subscriber.class, () -> new Subscriber());
}
public Subscriber () {
ActorRef mediator = DistributedPubSub.get(getContext().system()).mediator();
mediator.tell(new DistributedPubSubMediator.Put(getSelf()), getSelf());
}
@Override
public Receive createReceive() {
return receiveBuilder()
.match(String.class, msg -> {
System.out.println("Subscriber message received: " + msg);
Thread.sleep(10000);
})
.build();
}
}
any help is appreciated.
Thanks
