Best Way to Handle Large Data Processing – Threads vs ExecutorService?

Eric WalterMar 5 2025

I’m working on a Java application that processes a huge dataset, and I need to run a lot of computations on each record. Right now, I’m using multiple threads with Thread and Runnable, but I’m wondering if switching to ExecutorService (like FixedThreadPool or ForkJoinPool) would be a better option in terms of performance and resource management.

I have a few questions:

  • For CPU-heavy tasks, would an ExecutorService perform better than manually managing threads?
  • How do I properly handle thread lifecycles and avoid memory issues when using ExecutorService?
  • In what situations would ForkJoinPool be a better choice compared to a fixed thread pool?
