Play framework with Akka Throttle for Output

Play framework with Akka Throttle for Output

1 AKKA Version
First of all, check with AKKA version I am using in play framework 2.4.3. I knew the version of AKKA really matters.

In my play framework project
> activator

activator> show compile:dependencyClasspath

It will list all the dependency jars.
akka-actor_2.10-2.3.13.jar

akka-slf4j_2.10-2.3.13.jar

So the version is AKKA 2.3.13.

2 Throttling Actor Messages
Add this in the dependency
  "com.typesafe.akka" %% "akka-contrib" % "2.3.13",

Initiate the Akka as follow
  val contextIOActor = Akka.system.actorOf(ContextIOActor.props, name = "contextio-actor")
  val contextIOThrottler = Akka.system.actorOf(Props(classOf[TimerBasedThrottler], contextio_throttle msgsPer 60.second), name = "conetxt-io-throttler")
  contextIOThrottler ! SetTarget(Some(contextIOActor))

Then all we need to do is to send message to the contextIOThrottler, it will just throttle that and redirect the message to target.
