E.g., a change in credit card number in a DB triggers an action in a separate microservice (say to check that the CC is valid, etc.). Event-driven architecture, where a service operates in response to a change in data.Capture every change that occurred to your data, either for auditing, SCD2, etc., where you need to see every historical change.What & Why CDCĬDC (Change Data Capture) refers to capturing all the changes to a dataset/table and making it available for downstream systems to do as required. We will also go over a project that shows how every change to data in a transactional database can be captured and made available for analytics as an SCD2īy the end of this post, you will clearly understand what CDC is and the different types of CDC, and you have built a CDC project with debezium. This post will review what CDC is and why we need it.
