Thread Pools

Thread pools are a concurrency design pattern that manages a collection of worker threads to execute tasks efficiently. They pre-create a fixed or dynamic number of threads to handle incoming tasks, avoiding the overhead of creating and destroying threads for each request. This improves performance and resource management in multi-threaded applications.

Also known as: ThreadPool, Executor Service, Worker Pool, Thread Pooling, Thread Management

Why learn Thread Pools?

Developers should use thread pools when building applications that require handling multiple concurrent tasks, such as web servers, database connections, or parallel processing jobs. They are essential for optimizing system resources, reducing latency, and preventing thread exhaustion in high-load scenarios, making them a key component in scalable software design.
