Designing a domain error handling model involves classifying errors as transient or permanent to define explicit recovery expectations. You structure robust error taxonomies to categorize user-facing, internal, and system errors, ensuring clear propagation paths for improved resilience.

A circuit breaker is an error recovery strategy used to maintain service availability when downstream systems fail. You apply circuit breakers alongside retries with backoff and fallbacks when designing domain error handling schemes to prevent cascading failures during transient system faults.

The best way to structure error payloads is to include contextual data like correlation IDs, request IDs, and stack traces. This structured domain error specification ensures your payload is suitable for direct integration with standard logging and monitoring systems to streamline debugging.

To apply backoff strategies and fallbacks to a payment service, you distinguish transient payment gateway timeouts from permanent credential misconfig errors. You then outline concrete recovery paths, applying retries with backoff for transient timeouts and user prompts for permanent misconfigurations.

You should not use retry strategies for permanent errors like credential misconfigurations or invalid user inputs. In your domain error taxonomy, permanent errors require fallbacks or user prompts instead of retries with backoff, which are reserved exclusively for transient system failures.
