Consider a scenario where you have a large number of short-lived asynchronous tasks. Which type of ExecutorService would you consider using and why?

  • CachedThreadPoolExecutor: A thread pool that dynamically creates and recycles threads.
  • FixedThreadPoolExecutor: A fixed-size thread pool with a specific number of threads.
  • ScheduledThreadPoolExecutor: A thread pool for scheduling tasks at a fixed rate or delay.
  • SingleThreadPoolExecutor: A single-threaded ExecutorService.
In this scenario, the CachedThreadPoolExecutor is suitable. It dynamically adjusts the number of threads based on the workload, making it efficient for short-lived tasks. SingleThreadPoolExecutor and FixedThreadPoolExecutor have limitations for such cases, and ScheduledThreadPoolExecutor is designed for scheduling tasks, not managing short-lived tasks.
