Go Routine Patterns: Concurrency, Worker Pools, Graceful Shutdown & Retry Logic

Overview

This repository provides idiomatic Go patterns for concurrency, including graceful shutdown, worker pools, retry logic, and error handling. Each example is paired with a Mermaid sequence diagram for clarity.

Features

• Graceful shutdown with context and WaitGroup
• Signal handling for clean exits
• Worker pool implementation with dynamic tasks
• Retry logic with safe channel operations
• Timeout-based shutdown
• Error handling and logging
• Visual sequence diagrams with channels as actors

Notes

• For unbuffered channel
  • Send to channel ch <- true, must have a matching receive <-ch happening at the same time. If not it will be blocked on send. Because it doesn't have storage capacity.
