Dealing with unhandled messages

You can log any unhandled messages in an actor by overriding the unhandled method, like so:

class SomeActor extends Actor with ActorLogging {

override def unhandled(message: Any): Unit = {

log.warn(

"Unhandled message {} message from {}", message, sender()

)

super.unhandled(message)

}

}

We’ll start with a minimal protocol to model the most important interactions:

Between client and StatisticsProvider regarding the request to compute the reach of a tweet

Between StatisticsProvider and UserFollowersCounter

Between StatisticsProvider and Storage
