Akka - child actors restarted when parent actor is restarted

Question

I have a hierarchy of singleton actors. The parent supervises and coordinates the children. I need to keep child actors running when the coordinator is restarted. Is there a way to prevent child actors from restarting when their parent is restarted or should I rethink my actor hierarchy? I have been looking into akka supervision strategy but couldn't find a definitive answer.

Answer 1

Children are restarted in the preRestart callback, so if you override it on the parent and do not call super.preRestart the children will not be restarted when the parent is.
