Akka HTTP, although uses streams to express some concepts are easy to integrate with actors -- so you don't need to use streaming directly if you don't want to. I personally think the danger is usually overusing streams with new projects, so you can safely stick for actors for now, and grow into streams as necessary. I firmly believe their use cases become more natural as you build your application, and it will be easy to grow their use step by step instead of all in once. > It's very difficult to us to evaluate if we're going to succeed or fail > with akka-stream as we can't find what type of use case is intended to. > Streams simplify the development of actor systems is: - the use-case fits the streaming model, i.e. you were already thinking in a processing pipeline or layered architecture even when you imagined it doing it with actors. Streams are generally better in expressing processing steps and not a good fit when you have instead a web of domain operations. - you need backpressure. Akka Streams handle it for you and implementing correct backpressure is a daunting task with plain actors. > As system architect it's difficult to explain why we should go or not go > with Stream with all the consequences (e.g. dev team to learn an entire new > technology (not easy task)). > I would say, go with plain actors if you are comfortable with that one. Streams is an auxiliary, helper technology it is not fundamentally necessary to be used. As it is a new technology I expect more and more patterns to emerge in the long term, helping these decisions. You don't need to jump on it right away. -Endre > > I would like to emphasis that Spay or akka-http is not really the issue > both are ok.
