I am newbie to Akka, Akka not executing parallely with out Routers.
Kindly find my Producer.java & Consumer.java for reference.
*Below code executes jobs one by one*
ActorRef actorRef = system.actorOf(Props.create(Consumer.class));
actorRef .tell(job1..)
actorRef .tell(job2..)
actorRef .tell(job3..)
actorRef .tell(job4..)
*Below code executes jobs parallely, it spans 4 thread*
ActorRef printNumbersConsumer =
system.actorOf(Props.create(Consumer.class).withRouter(new
RoundRobinRouter(4)),"router");
actorRef .tell(job1..)
actorRef .tell(job2..)
actorRef .tell(job3..)
actorRef .tell(job4..)
Kindly correct if my understanding is wrong.
