domain-event-catalog

A domain event catalog standardizes domain event authoring within bounded contexts to ensure reliable asynchronous communication. It provides rigorous framework for defining, versioning, and publishing events to solve undocumented service coupling and unreliable event emission.

The transactional outbox pattern eliminates dual-write failures by coupling event persistence directly with database transactions. This ensures reliable event emission by writing events to an outbox table within the same transaction as your business data changes.

Domain event versioning requires clear strategies for additive and breaking schema changes. By maintaining a canonical envelope specification and applying strict versioning rules, consumers remain stable during event evolution within your bounded contexts.

A canonical event envelope must carry essential metadata like correlation IDs and tenant IDs for traceability. This standardized envelope ensures every event provides the necessary context for reliable asynchronous communication across services.

Event storming applies to design and implementation phases where event-driven architecture requires strict naming conventions and envelope schemas. It helps define bounded contexts and establish the domain events needed for reliable decoupled systems.

Yes, the domain event catalog framework satisfies requirements for event idempotency and audit-compliant retention policies. It enforces strict naming conventions and envelope schemas to ensure reliable asynchronous communication across bounded contexts.
