Go Concurrency Patterns

wshobson/agents

A solid collection of battle-tested Go concurrency patterns that covers the essentials: worker pools, fan-out/fan-in pipelines, semaphore-based rate limiting, and graceful shutdown handling. The code examples are production-ready and demonstrate proper context usage, channel management, and synchronization primitives. What I appreciate is the focus on real patterns you'll actually encounter, like bounded concurrency and proper goroutine lifecycle management. The graceful shutdown pattern alone is worth having on hand since most tutorials skip this crucial piece. Perfect reference when you need to implement concurrent processing or debug those inevitable race conditions that pop up in Go services.

Go Concurrency Patterns

Production patterns for Go concurrency including goroutines, channels, synchronization primitives, and context management.

When to Use This Skill

  • Building concurrent Go applications
  • Implementing worker pools and pipelines
  • Managing goroutine lifecycles
  • Using channels for communication
  • Debugging race conditions
  • Implementing graceful shutdown

Core Concepts

1. Go Concurrency Primitives

PrimitivePurpose
goroutineLightweight concurrent execution
channelCommunication between goroutines
selectMultiplex channel operations
sync.MutexMutual exclusion
sync.WaitGroupWait for goroutines to complete
context.ContextCancellation and deadlines

2. Go Concurrency Mantra

Don't communicate by sharing memory;
share memory by communicating.

Quick Start

package main

import (
    "context"
    "fmt"
    "sync"
    "time"
)
