error-handling-patterns

Implement resilient error handling by selecting appropriate error models for each language, defining explicit error classes, and applying retry, circuit-breaker, and graceful degradation strategies.

Choosing between exceptions and Result types depends on your language's error model and system architecture. Compare exceptions against Result or Option types to design APIs with clear error semantics and predictable recovery paths.

Use a circuit breaker pattern in distributed architectures to prevent cascading failures across service boundaries. It monitors error rates and interrupts traffic to failing services, enabling graceful degradation and predictable recovery.

Apply retry strategies with exponential backoff and jitter to avoid overwhelming services during transient IO failures. Combine retries with circuit breakers to stop retry loops when downstream services are completely unavailable.

Yes, this approach works for debugging production issues by providing structured error-handling patterns and clear diagnostics. It defines explicit error classes and aggregation techniques to trace failures across service boundaries accurately.

Graceful degradation is an error-handling strategy that maintains partial system functionality during IO failures. It ensures applications fail predictably by returning fallback responses instead of crashing when service boundaries or networks fail.
