Like mapAsync but Future CompletionStage results are passed downstream as they arrive regardless of the order of the elements that triggered them.

def mapAsyncUnordered[T](parallelism: Int)(f: Out ⇒ Future[T]): Repr[T]

Description

Like mapAsync but Future CompletionStage results are passed downstream as they arrive regardless of the order of the elements that triggered them.

If a Future CompletionStage fails, the stream also fails (unless a different supervision strategy is applied)

emits any of the Future s CompletionStage s returned by the provided function complete

backpressures when the number of Future s CompletionStage s reaches the configured parallelism and the downstream backpressures

completes upstream completes and all Future s CompletionStage s has been completed and all elements has been emitted
