async

It would be good to see an asynchronous example using HystrixObservableCommand, also there is lack of example for using request cache which hystrix provides and play integration.

I decided to take a bit different approach and reimplement hystrix in play API:

Yes, you're right, there are a couple of things missing. Your approach seems far more serious, though. I never intended this repo here to be some kind of reusable library, just a playground.

As for the async example, it would be straightforward to startup an actor, give it a e.g. ReplaySubject and then return this (as opposed to just sleep in some Future). Then again, Akka already comes with many of Hystrix' conveniences like thread isolation, fault tolerance, or bulk heading but is already integrated nicely into Play. I would say, the dashboard maybe the piece that requires most user implementation. I think, I rather see a comparison between Hystrix and Akka.
