Parallel execution of methods

I have an application that sends multiple request to my spray-can 1.3.1 server.

FireBug shows me, that these requests are triggered in parallel.

However, on the server these request are handled strictly serially.

I think I need to somehow configure the spray server to handle multiple requests in parallel - but how?

The server is started like that:

object Server extends SimpleRoutingApp{  
  def main(args: Array[String]): Unit = {
    implicit val system = ActorSystem()
    startServer("0.0.0.0", port = 8080) {
      get{
        pathSingleSlash {
          complete{
            HttpEntity(
              MediaTypes.`text/html`,
              Template.txt
            )
....
Solution

  • As Spray routing is synchronous in an actor, you will need to do something else to make it handle multiple requests in parallel.

    1. Using the Detach directive: This directive will spawn a new actor to process that request.
    2. Using an actor-per-request
