How do I Invoke 3 REST endpoints in parallel?

Question

I have to invoke REST endpoints A, B & C in parallel and combine the resulting JSON from each into one JSON. All REST endpoints reside on different servers.

My initial design calls for 3 Callables executed via FutureTasks. I will then do a Future.get(1000ms) on each FutureTask until they return a value. Is this how you would solve this problem ?

Answer 1

That's how I would do it. I really like the Future interface.
