In previous post we learned about supervision and how to restart a behavior in case of failures. Related to that is the actor’s lifecycle and how to watch an actor to be notified when it’s terminated. Classic untyped actors have lifecycle hooks; preStart, preRestart, postRestart and postStop. Some of those...

Supervision semantics in Akka Typed have changed slightly compared to supervision in classic untyped actors. Untyped actors are by default restarted when an exception is thrown. The default for typed actors is instead to stop the failing actor. In this blog post I will show how to install restarting supervision...

Message protocols are an essential part of designing actor based systems. The interaction between actors are often stateful and messages are supposed to be sent in a certain order, e.g. establishing a session, replying to a certain request, or acknowledging reception. In this blog post we will look at how...

In this post we will look...
