Description copied from interface: ReactiveStreamsTerminalFutureOperations

Perform a forEach operation over the Stream, without closing it, consuming only the specified number of elements from the Stream, at this time. More elements can be consumed later, by called request on the returned Subscription

 
     ReactiveTask next = FutureStream.builder().of(1,2,3,4)
                                  .futureOperations()
          					    .forEach(2,System.out::println)
          						.join();
          
     System.out.println("First batch processed!");
     
     next.request(2);
