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?
