A naïve approach would be to create a thread pool and run each job off it, but soon we realize that this is not optimum because we cannot ascertain the utilization of each I/O resource due to unpredictability of the threads being scheduled by the OS. We also observe that even though several concurrent jobs have similar I/O tasks, we are unable to batch them in our first approach.
