Scala Reactive Programming

Step1 – Use the PersistenceActor trait

If want to develop an Akka Persistence component or Actor, add the PersistenceActor trait to this Actor, as shown here:

class HelloWorldActor extends PersistentActor{ 
  // Actor State goes here 
  // Actor Operations goes here 
} 

Here, PersistentActor is a trait defined in the akka.persistence package. It marks our HelloWorldActor as a Persistence Actor.
