CDC (Change Data Capture)

overview

Change data capture (CDC) refers to the tracking of all changes in a data source (databases, data warehouses, etc.) so they can be captured in destination systems. In short, CDC allows organizations to achieve data integrity and consistency across all systems and deployment environments. Additionally, it allows organizations to use the right tool for the right job by moving data from legacy databases to purpose-built data platforms, such as document or search databases and data warehouses.
