Part 10/18:
The speaker describes a data mesh-inspired architecture that champions publishing domain-specific events via the transactional outbox pattern. Each service (e.g., order management) generates and publishes domain events—like "OrderCreated"—which are captured in an outbox table. These are then ingested into the data platform, forming append-only fact tables immersed in a consistent semantic layer.
This approach ensures that the source of truth—actual primary data—is preserved, while data engineering teams focus on processing and transforming data without embedding business logic—this adheres to domain ownership principles while decoupling source and consumer layers.
