Circuit Breaker vs. Retry Pattern
Below are the differences between Circuit Breaker and Retry Pattern:
Aspect | Circuit Breaker Pattern | Retry Pattern |
---|---|---|
Purpose | Prevents repeated calls to a failing service by temporarily blocking requests when a failure threshold is exceeded | Retries failed operations automatically with the hope of success on subsequent attempts |
Response to Failures | Blocks requests to a failing service to prevent cascading failures and reduce load on the system | Retries failed operations without blocking, with the goal of eventually succeeding |
State Management | Maintains states (e.g., closed, open, half-open) based on the health of the service and previous failures | Does not maintain state; each failure is retried independently |
Fault Detection | Monitors the health of services to detect failures, transitioning between states based on predefined thresholds | Detects individual failures and retries them immediately or after a short delay |
Granularity of Control | Provides fine-grained control over service access, allowing for dynamic adaptation based on service health | Offers less control over retries, typically retrying all failed operations with the same settings |
Handling Transient Faults | Effectively handles transient faults by blocking requests and allowing the service to recover | Attempts to mitigate transient faults by retrying failed operations, but may not prevent cascading failures |
Latency Impact | May introduce latency during state transitions or when requests are blocked in the open state | Can introduce latency due to repeated retries, especially if retries are performed sequentially with fixed intervals |
Circuit Breaker vs. Retry Pattern
In software development, ensuring that applications remain resilient in the face of failures is crucial. Two key strategies that developers employ to enhance resilience are the Circuit Breaker and Retry patterns. These patterns offer solutions to handle failures gracefully and maintain system stability.
