Crossing Boundaries with Integration Events
Summary
Denis Kyashif explains how to design integration events between bounded contexts in Domain-Driven Design, focusing on creating stable contracts that don’t expose internal domain models. The article covers envelope-based messaging, event design choices, and patterns like transactional outbox, idempotent processing, and deduplication to ensure reliability in distributed systems. It also discusses when integration events are not appropriate and how to translate domain facts at the edge of boundaries.
