How To parallel compute in streams

[lukas.c...@gmail.com]

Hello,

i implemented the example from http://fruzenshtein.com/simple-akka-use-case/ and wonder how to implement 

this pattern as akka streams. Especially the line for dynamic actor spawning confuses me.

files.foreach(file => context.actorOf(FileReaderActor.props) ! file)

Which pattern in akka streams does what i am looking for? 

Broadcast / Merge with a fixed worker pool?

BroadcastHub and MergeHub with an e.g. Actor in between for processing?

Thanks

Lukas

Perhaps mapAsync ( http://doc.akka.io/api/akka/2.5/akka/stream/javadsl/Flow.html#mapAsync[T](parallelism:Int,f:akka.japi.function.Function[Out,java.util.concurrent.CompletionStage[T]]):akka.stream.javadsl.Flow[In,T,Mat] ) might come in handy here?
