Hello dear community.
Is it okay to wrap a blocking iterator when creating a Source? I have a
blocking API, which I want to hide behind the Source. Here is an example (I
suspect I might need to put blocking code on another executor, is this the
case?):
object playground extends App {
implicit val system = ActorSystem()
implicit val materializer = ActorMaterializer()
val blockingIterator: Iterator[Int] =
new Iterator[Int] {
override def next(): Int = {
Thread.sleep(1000)
Random.nextInt(10)
}
override def hasNext: Boolean = true
}
val source = Source(() => blockingIterator)
source.runWith(Sink.foreach(println))
}
