CDC: from zero to hero

Change data capture (CDC) is a set of software development patterns that enable the creation of reactive infrastructure, simplify microservices architecture, and break monoliths into smaller services. CDC allows for real-time analysis of data moved to external systems by obtaining a stream of events regarding the addition, modification, and deletion of rows in an online transaction processing (OLTP) database. This transforms the database into an event-driven system with low latency responsiveness. CDC is particularly useful for enabling reactive interactions between infrastructure components and implementing patterns needed to build microservice architecture. It can be applied to various scenarios, such as replication to a DWH, cache invalidation, update search indexes, and more.
