Guaranteed messages delivery:Challenges of transactional Outbox & Inbox patterns by Aleksandr Gromov

In distributed systems, communication between different components is crucial. However, physical networks can sometimes experience disruptions. A network connection might be temporarily lost, but business transactions must remain consistent. Dealing with lost events or duplicates becomes a frustrating issue, and detecting such occurrences can be especially challenging as the system scales. So how do we address these challenges? Transactional outbox and inbox patterns offer a solution. While these patterns are well-known in the world of microservices, their implementation often raises multiple questions. Join me to explore these patterns in-depth, understand their potential pitfalls, and learn how to implement guaranteed message delivery effectively.
