Hi, I have been trying to find some solid examples for using Observables/Callbacks/Futures to delegate long running tasks (which return the response to be sent back) over to separate threads. The idea is that the handler method simply spawns an async task and whenever that async tasks completes, we send back the response without making the handler method/worker threads wait for the async task to finish. Any pointers/examples would be appreciated. -- Girish Sharma
