Akka with Remote Actors and Durable mailboxes - scala

Question

I would like configure Akka to use remote actors with redis durable mailbox, like below.
common.conf file:
akka {
actor {
mailbox {
redis {
hostname = "127.0.0.1"
port = 6379
}
}
provider = "akka.remote.RemoteActorRefProvider" }
remote {netty {hostname = "127.0.0.1" }}
}
and my application.conf file:
calculatorActor {include "common"}
remotecreation {
include "common"
akka {
actor {
deployment {
/advancedCalculator {
router = "round-robin"
nr-of-instances = 200
target {
nodes = ["akka://CalculatorApplication#127.0.0.1:2552"]
}
}
}
}
remote.netty.port = 2554
}
}
This is configuration is derived from akka-sample-remote. When I run the application, I don't see any connections ever made to the redis side (durable mailbox!). Redis logs only contains:
0 clients connected (0 slaves)

You must specify a dispatcher with the correct mailbox type.
from the docs:
my-dispatcher {
mailbox-type = akka.actor.mailbox.RedisBasedMailboxType
}
and then create your actor with this dispatcher:
val myActor = system.actorOf(Props[MyActor].withDispatcher("my-dispatcher"), name = "myactor")
