Circuit Breaker Pattern

Introduction

The circuit breaker pattern helps prevent cascading failures in distributed systems by stopping requests to a failing service.

How It Works

• Closed: Requests flow normally.
• Open: Requests are blocked after failures cross a threshold.
• Half-Open: Some requests are allowed to test if the service has recovered.

Benefits

• Prevents system overload.
• Improves fault tolerance.

Conclusion

Circuit breakers are a must-have for building resilient distributed systems.
