you just need to create a new actor with the same persistenceId. there
is no special identifying information you need to send during recovery.
note that in order to recover on a different node, this assumes that you
are using one of the distributed persistence backends like cassandra,
and not a local backend like leveldb.

Thanks for the help.
And how do I restore the same actor (state) on another node? Would it
happen automatically if I will use the same id ? Do I need to use the
Recover class in some manner ?
Thanks

Hello Barak,
Killing an Actor will “remove it from memory” (make it eligable
for GC), same rule holds for Persistent Actors.
To kill it and keep the persistent state just send a |PoisonPill|
or an application level message that will ask the actor to
|context stop self|.
If you want to discard the same for the given persistenceId, you
can during postStop() trigger |deleteMessages(lastSequenceNr)|
(and |deleteSnapshots(SnapshotSelectionCriteria.Latest)| for
snapshots).
Hope this helps, happy hakking!
