Circuit Breaker Module
Core details
Title
*
Description
*
A Circuit Breaker is a design pattern that prevents cascading failures in distributed systems by detecting when a service is not responding and stopping requests to it temporarily. It "trips" the circuit to fallback mode after failures, allowing recovery time.

Usage & Trade-offs
All fields support markdown. Use concise bullets and concrete situations.
When to use it
*
Use Circuit Breaker when: - Integrating with unreliable external services or microservices. - Building resilient applications in cloud-native environments. - Handling high-availability requirements for fault-tolerant systems. - Preventing one failing component from affecting the entire application.
Pros
*
- Enhances system resilience by isolating failures. - Reduces load on failing services, aiding faster recovery. - Provides graceful degradation with fallback mechanisms. - Configurable thresholds for failure detection and reset timeouts. - Integrates well with monitoring tools for health checks.
Cons
*
- Requires tuning parameters to avoid false positives/negatives. - Adds complexity to the codebase with state management. - Potential for increased latency during fallback invocations. - Overuse can lead to unnecessary circuit trips in noisy environments. - Not a silver bullet; needs complementary patterns like retries.
Notes
Note: Libraries like Resilience4j (Java) or Polly (.NET) simplify implementation. Combine with health checks and bulkhead patterns for better isolation. Log circuit state changes for post-mortem analysis.
