A Circuit Breaker Alone Won't Save Your Database

Short summary

Circuit breakers prevent wasted requests to failing dependencies but don't protect databases—add rate limiters to cap traffic and local caching as fallback. Together they ensure production systems remain resilient under cascade failures.

• •Circuit breakers stop calling failing dependencies but don't protect the database
• •Rate limiters and local caching are required to prevent cascading failures
• •Implement rate limiting at the service level where dependency-specific logic lives
