Patterns That Matter
Distributed patterns: circuit breaker & idempotency
Lesson 5 of 5
The resilience patterns GoF never covered but every staff review assumes — circuit breakers, retries, and idempotency keys.
What you'll learn
- Use a circuit breaker to fail fast after repeated downstream failures.
- Understand retries with backoff and why they need idempotency.
- Use idempotency keys to make retried operations safe.
