*Solution 1:* Akka persistence (the parent only) with sharding can solve that problem for you, basically the parent actor will be re-instantiated somewhere else and resume from its last state and replay any message that follows.
*Solution 2:* I used a similar concept where a type of parent is backed by an ORSet (Akka distributed data) where in case it dies, a supervisor will redistribute such ORSet among the remaining parents of its type. Messages are removed from the ORSet only after they have been processed *-think of this as a two-phase commit system-* Hope that helps, Guido.
