Goroutines aren’t “magic” — real performance comes from disciplined patterns.
In my new article, I share the 5 concurrency techniques I reach for in production Go services:
✅ Worker Pool (stop goroutine explosions)
✅ Fan-Out / Fan-In (parallelize external calls)
✅ Pipelines (clear, testable data flows)
✅ Timeout & Retry with select (never hang on I/O)
✅ Rate Limiting (protect APIs & your own system)
👉 Read the full guide and level up your Go concurrency design.
