Hi, I have a akka stream. In the middle of the stream the map() calls a remote service (WSClient),which returns a completionStage. I want the source does not emit the next element before the completionStage finished.
To be more efficient, I want the source emit batch of elements, then wait for all the completionStage finished, then emit another batch of elements. How to do it in akka-stream? Thanks for your help very much.
