I cannot stop an actor running akka stream even with killswitch. How do I
properly stop an actor running an akka stream?
private def startStream(maybeOffset: Option[ProcessedEventOffset]): Unit = {
implicit val materializer = ActorMaterializer()
val publisher = SomePublisher
val (killSwitch, done) = Source
.fromPublisher(publisher)
.viaMat(KillSwitches.single)(Keep.right)
.toMat(Sink.ignore)(Keep.both)
.run()
done.onComplete {
case Success(_) =>
context.stop(self)
case Failure(e) => // receive an error from the stream
log.error(e, "Error while processing stream")
context.stop(self)
}
maybeSwitch = Some(killSwitch)
}
