Default supervision strategy

By default, the Akka system looks for a few exception types from failure messages received from child Actors. Let's take a look at those scenarios.

The default supervision strategy will stop the failing child Actor in case of:

  • ActorInitializationException
  • ActorKilledException
  • DeathPactException

Note that in case of exception, it'll restart the failing Actor.

With this information, let's try implementing one strategy on our own.
