two ways to do it with CompletableFutures:

  1. fire off 10 CompletableFutures that make your requests then send the thread to sleep for 1s - see runAsync() and supplyAsync() methods.
  2. execute 1 CompletableFuture and sleep 1/10th of a second.

If you store the CompletableFutures in a list/map (whatever works for your situation best) you can then .get() the answers later when you need to access the results.
