6 months ago UPDATE. I managed to broadast message to all routees across the cluster by creating an extra clustered group:
deployment {
/echo {
# router = round-robin-pool
router = broadcast-pool
# nr-of-instances = 4
cluster {
enabled = on
max-total-nr-of-instances = 4
max-nr-of-instances-per-node = 2
allow-local-routees = on
use-role = Upload
}
}
/echo_group {
# router = round-robin-group
router = broadcast-group
routees.paths = ["/user/echo"]
cluster {
enabled = on
max-total-nr-of-instances = 2
max-nr-of-instances-per-node = 1
allow-local-routees = on
use-role = Upload
}
}let system1 = System.create "cluster-system" (configWithPort 5000)
let system2 = System.create "cluster-system" (configWithPort 5001)
let system3 = System.create "cluster-system" (configWithPort 5002)
let echoActor (mailbox: Actor<_>) (msg: string) =
let nodeAddress = Cluster.Get(mailbox.System).SelfUniqueAddress
match msg with
| "ping" -> logInfof mailbox "Received ping on %A" nodeAddress
| _ -> ()
ignored ()
let pool1 =
spawn
system1
"echo"
{ props (actorOf2 echoActor) with
Router = Some(FromConfig.Instance :> RouterConfig)
}
let pool2 =
spawn
system2
"echo"
{ props (actorOf2 echoActor) with
Router = Some(FromConfig.Instance :> RouterConfig)
}
let pool3 =
spawn
system3
"echo"
{ props (actorOf2 echoActor) with
Router = Some(FromConfig.Instance :> RouterConfig)
}
pool1 <! "ping" // Messages are only sent to the pool1, not all routees
pool2 <! "ping" // Messages are only sent to the pool2, not all routees
let r1: IActorRef<string> = typed <| system1.ActorOf(Props.Empty.WithRouter(FromConfig.Instance), "echo_group")
r1 <! "ping" // Message are sent to all clustered pool routees!
let r2: IActorRef<string> = typed <| system2.ActorOf(Props.Empty.WithRouter(FromConfig.Instance), "echo_group")
r2 <! "ping" // Message are sent to all clustered pool routees!This kind of works, but is this the only way to broadcast messages across the whole cluster pool?

Scenario
We have a clustered pool router and want messages to be broadcasted to all routees in the cluster.
Problem
Messages are only sent to the local router.
Code example
This example is in F# script but should be easy to understand
We configured a pool of 4 instances with max 2 instances per node. So pool1 and pool2 get 2 instances but pool 3 doesn't get any. Now how do I make a message to reach all routees in the cluster? Sending a message to pool1 broadcasts them only to 2 routees belonging to the pool1, indeed. Is it possible to send messages across the whole cluster?
