Akka FAQ

1. Constructor vs preStart() - Is it ok to create child actors in the constructor vs doing it in preStart() ?

Both the constructor and preStart() are called during a restart. So it's absolutely fine to created child actors in the constructor. (Aside: when using preStart() always call super.preStart() first). If for some reason you don't want to create children during restart then use preStart() for creating and make sure you overrride preRestart()
