Go’s concurrency model is built around goroutines and channels. Here are a few patterns I use regularly.
Worker Pool
A fixed number of workers process tasks from a shared queue. This limits resource usage while keeping throughput high.
Fan-Out / Fan-In
Start multiple goroutines to process different parts of a job, then combine the results back into a single channel.
Pipeline
Chain channels together so each stage of processing runs concurrently. Clean and composable.
More examples coming soon.
