I am trying to assign a dispatcher to be used for my http server (using the
new Akka HTTP Server) and can’t get it to honor my pool size settings.
Logs show it is using the dispatcher, but visualvm shows it is not using
the core pool size settings. Loos like it might be using the defaults for
a thread-pool-executor.
All I did was modify the example:
1. import akka.http.Http
2. import akka.stream.FlowMaterializer
3.
4. implicit val system = ActorSystem()
5. implicit val materializer = FlowMaterializer(*MaterializerSettings*(
*system*).withDispatcher(*“myhttpRequestHandler.dispatcher"*))
6.
7. val serverBinding = Http(system).bind(interface = "localhost", port =
8080)
8. serverBinding.connections.foreach { connection => // foreach
materializes the source
9. println("Accepted new connection from " + connection.remoteAddress)
10. }
11. …
myhttpRequestHandler {
dispatcher {
type = Dispatcher
executor = *"thread-pool-executor"*
name = httprequesthandler-dispatcher
thread-pool-executor {
core-pool-size-min = 100
core-pool-size-factor = 2.0
core-pool-size-max = 100
}
throughput = 5
}
}
[INFO] [2015-01-15 17:24:27,516] [DUDE-myhttpRequestHandler.dispatcher-79]
HttpRequestHandler(akka://DUDE): Accepted new connection from
/127.0.0.1:54046
What am I missing?
Thanks,
Randy Fox
