AI API Gateway
Retry Logic Implementation
Advanced fault tolerance patterns for resilient API communication. Implement intelligent retry mechanisms, circuit breakers, and exponential backoff strategies to ensure high availability and reliability of your AI API gateway infrastructure.
Retry Mechanism Visualization
Visual representation of exponential backoff and circuit breaker patterns in action.
Exponential Backoff
Intelligent delay calculation that increases between retry attempts to prevent overwhelming downstream services. Standard pattern: delay = baseDelay × 2^(retryCount-1).
- Base delay configuration
- Maximum retry count
- Jitter addition for randomization
- Maximum delay caps
Circuit Breaker Pattern
State-based protection mechanism that trips when failure threshold is exceeded. Prevents cascading failures by temporarily stopping calls to failing services.
- Closed: Normal operation
- Open: Circuit tripped, fast failure
- Half-Open: Limited trial calls
Error Classification
Intelligent error categorization to determine retry eligibility. Transient errors (timeouts, rate limits) are retried, while permanent errors (validation, auth) fail immediately.
- Transient vs permanent errors
- HTTP status code mapping
- Custom error type definitions
- Error severity levels
Monitoring & Metrics
Comprehensive observability with detailed metrics tracking. Monitor success rates, error distributions, latency percentiles, and circuit breaker state transitions.
- Retry success/failure rates
- Circuit breaker state history
- Error distribution analysis
- Performance impact metrics
Retry Logic Configuration
Fine-tune your retry strategy with these configurable parameters. Adjust based on your specific reliability requirements and downstream service characteristics.
