The semaphore Package
Explore the semaphore package in Go to control goroutine access to shared resources. Learn how to implement a worker pool that limits concurrent goroutines using semaphore weights, Acquire, and Release methods. This lesson helps you understand how to manage concurrency effectively to avoid race conditions and synchronize goroutine completion.
We'll cover the following...
What is a semaphore package?
The last lesson of this chapter presents the semaphore package, which is provided by the Go team. A semaphore is a construct that can limit or control the access to a shared resource. As we are talking about Go, a semaphore can limit the access of goroutines to a shared resource but originally, semaphores were used for limiting access to threads. Semaphores can have weights that limit the number of threads or goroutines that can have access to a resource.
The process is supported via the Acquire() and Release() ...
