Hi Gary, it's as simple as setting a dispatcher for a Flow.
val flow = Flow[String].via(myBlockingStage).withAttributes(ActorAttributes.dispatcher(“my-configured-blocking-dispatcher”)) (setting a dispatcher also implies an asynchronous boundary). Of course try to avoid these blocking APIs, you could for example setup a timer (GraphStage has support for that) which checks the future regularly for completion and pushes once it's finally completed. -- Cheers, Konrad 'ktoso’ Malawski Akka @ Lightbend On 24 February 2016 at 02:50:54, Gary Struthers ([email protected]) wrote: I'm calling a 3rd party Java library that returns a Java Future from my GraphStageLogic onPush(). I want the future to complete before calling pull(in). Simply blocking with Java Future's get(...) works. So do I really need to do this within a blocking-dispatcher? If so, how do I setup onPush() to use the dispatcher?
