eventmodeling-validating-event-models-checklist

To validate event-sourced CQRS models for production readiness, systematically apply a 16-point architectural checklist across 7 phases to identify anti-patterns and verify domain-driven design compliance before implementation.

Common anti-patterns in event modeling architecture include calculation events, circular dependencies, and improper state management, which violate domain-driven design principles and compromise production readiness.

To check command handler state isolation in event-sourced systems, evaluate command handlers against architectural validation criteria to ensure they are correctly isolated from read model projections and event streams.

You need to audit event streams and read model projections during the architectural review phase of an event-sourced project to ensure streams, command handlers, and read models are correctly isolated and ready for implementation.

Yes, this event model validation framework works for banking and e-commerce domains, applying domain-driven design principles to verify architectural consistency and production readiness in complex event-sourced systems.

When validating event-sourced architectures against design principles, limitations include the requirement for complete event model documentation and systematic evaluation, as the framework cannot validate undocumented streams or missing architectural components.
