MDM #16. Real-Time Master Data Architecture: CDC, Events, Consistency and Reconciliation
Real-time Master Data Management is often described too simply. The usual architecture diagram looks like this: Master Data Changes → Event Stream → Every System Updates Immediately That diagram hides most of the difficult engineering decisions. Should every master-data change really propagate immediately? What happens when the same event is delivered twice? What if version 103 reaches a consuming system before version 102? What happens when one downstream application is unavailable for six hours? How does the enterprise prove that all critical consumers eventually converged on the same mastered state? And where does a broader concept such as Data Fabric actually fit? Real-time MDM is not about making every master-data update instantaneous. It is about delivering the right mastered state to the right consumer within the business latency the process actually requires—and being able to recover when distributed systems disagree. This article examines that archi...
