Circuit Breaker & Resilience Patterns

This skill focuses on the 'Self-Healing' nature of a system, ensuring it doesn't crash when one part is struggling.

Instructions

1. Implement Circuit Breakers for all external service calls (e.g., using Hystrix or Resilence4j patterns).
2. Define thresholds for 'Open', 'Closed', and 'Half-Open' states.
3. Design 'Fallback' mechanisms (e.g., show cached data if the DB is slow).
4. Implement 'Bulkheading' to isolate failures to a single component.
5. Set up 'Retry' logic with exponential backoff and jitter.

Examples

• "Protect my app from a slow Payment API using a circuit breaker."
• "Implement a fallback strategy for our recommendation engine."
