Creating a BalancingPool of actors

A BalancingPool tries to redistribute the work among the actors for performance improvement. In the BalancingPool, all actors share the same mailbox.

Getting ready

Just import the Hello-Akka project in the IDE; other prerequisites are the same as before.

How to do it...

1. Create a Scala file, Balancingpool.scala, in the package com.packt.chapter3.
2. Add the following imports at the top of the file:

      import akka.actor.{Props, ActorSystem, Actor} 
      import akka.routing.BalancingPool 

3. Define a simple actor as an example:

        class BalancingPoolActor extends Actor { 
          override def receive = { 
            case msg: String => println(s" I am ${self.path.name}") 
            case _ => println(s" I don't understand the message") 
        ..} 
        } 

4. Create a simple test application as follows:

        object balancingpool extends App { 
          val actorSystem = ActorSystem("Hello-Akka") 
          val router = 
           actorSystem.actorOf...
