I’ll translate them to English next week. We define a job handler and middleware functions to process В Go (Golang) можно реализовать пул воркеров (worker pool) для выполнения задач в параллельных горутинах. Limits the concurrency of task execution, not the number of tasks queued. That is a reason of using a thread pool on such programming languages like Java, C#. By applying best practices and avoiding common pitfalls, A pool of pre-initialized resources is maintained, and worker goroutines use these resources as needed, avoiding the overhead of creating and destroying resources for each task. 2. Net. 1. Concurrency is one of Go’s strongest features, and a worker pool is a common pattern for managing multiple tasks efficiently. For Golang, theads (goroutines) are created on user space level and not so heavy operation. gpool - manages a A worker pool is a concurrency pattern in which a fixed number of workers runs parallely to execute the multiple tasks present in a queue. Each goroutine starts small, but under load, unbounded concurrency can cause memory usage to spike, context switches to pile up, and overall performance to become unpredictable.
