SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Circuit breakers protect APIs from upstream failures by automatically halting traffic to unhealthy services and enabling faster recovery.

Core Features & Use Cases

  • Per-route circuit breaking using the a6 api-breaker plugin to prevent cascading failures.
  • Configurable unhealthy/healthy thresholds, cooldown timing, and custom responses.
  • Integration with upstream health checks and declarative YAML configurations for reproducible deployments.

Quick Start

Configure a route with the api-breaker plugin and observe automatic circuit opening and recovery after failures.

Frequently Asked Questions about a6-recipe-circuit-breaker

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I prevent cascading API failures from unhealthy upstreams?▼

Circuit breakers prevent cascading API failures by automatically halting traffic to unhealthy upstream services and enabling faster recovery after failures.

How do I configure per-route circuit breaking for my APIs?▼

Per-route circuit breaking is configured declaratively using YAML files, applying the api-breaker plugin to specific routes and upstreams to stop traffic to failing services.

Can I customize unhealthy status codes and cooldown timing for circuit breakers?▼

Yes, circuit breakers support configurable unhealthy and healthy status codes, failure and success thresholds, cooldown timing, maximum breaker duration, and custom break response content.

Does the api-breaker plugin integrate with upstream health checks?▼

Yes, the circuit breaker integrates with upstream health checks and declarative YAML configurations to automatically open circuits during failures and recover services.

What is the best way to return a custom response when an upstream circuit opens?▼

The best way to return a custom response is by configuring optional break response content within the api-breaker plugin settings on your route, defining exactly what clients receive.
