Transactional Outbox Pattern

Description

This is a lecture from the Cockroach University course “Event-Driven Architecture with Java”. In this lecture, students are introduced some of the principles of building microservices such as synchronous, and asynchronous messages, data isolation, and event-driven architecture. We discuss the dual-write problem that occurs when you try to build an event-driven system. We also discuss the transactional outbox pattern and how it can be used to avoid the dual-write problem. Finally, we introduce CockroachDB’s Change Data Capture which can be used in conjunction with the transactional outbox pattern to simplify the implementation of an event-driven system.
