Thanks for the reply, Patrik! In my use case Processor should send and receive multiple messages from other parts of the system and I thought that using single custom processor in a Flow is a more optimal approach then spawning multiple intermediate ask actors from mapAsync(I know that premature optimization is bad =) ). Howewer I realized that my current implementation feels too hacky(AFAIK there is no standart way to access materializer instance to create actor as it's child so I have to use ActorSystem etc.) so I'll stick with multiple ask inside mapAsync until it'll become a problem.
