FanIn-FanOut Concurrency Pattern in Golang
Understanding Go concurrency
Concurrency is a fundamental aspect of Go programming, and the Fan-Out, Fan-In pattern is a powerful tool for harnessing its potential. This pattern allows you to distribute work across multiple goroutines (Fan-Out) and then collect the results into a single stream (Fan-In), enabling efficient and scalable concurrent processing.
Fan-Out:
In the Fan-Out stage, a single task is divided into multiple smaller subtasks, which are then executed concurrently. Each subtask is assigned to a separate goroutine, allowing for parallel processing and improved resource utilization.
Fan-In:
In the Fan-In stage, the results or outputs from all the concurrently executing subtasks are collected and combined into a single result. This stage waits for all the subtasks to complete and aggregates their results, providing a unified output. By leveraging the Fan-Out, Fan-In pattern, you can effectively tackle a wide range of concurrent processing challenges.
