In Golang, a WaitGroup is a synchronization primitive provided by the sync package. It is used to wait for a collection of goroutines to finish executing. Here’s a breakdown of how it works:
Initialization: A WaitGroup is initialized and shared among goroutines.
Adding Goroutines: Before starting a goroutine, you call Add(n) on the WaitGroup, where n is the number of goroutines to wait for.
Decrementing: Each goroutine calls Done() when it finishes its work. This decrements the WaitGroup counter.
Waiting: The main goroutine calls Wait(), which blocks until the WaitGroup counter is zero, meaning all goroutines have finished.
Golang Worker Pool
A worker pool is a pattern where a fixed number of worker goroutines are created to handle tasks from a shared job queue. This pattern helps to limit the number of concurrent goroutines and can improve efficiency and resource management.
Key Components:
Job Queue: A channel that holds tasks to be processed.
Workers: Goroutines that pick up tasks from the job queue and process them.
Dispatcher: Manages the pool of workers and assigns tasks from the job queue to the workers.
