# Change Data Capture

Change Data Capture (CDC) synchronization uses the built-in data auditing features supported by most RDBMS systems.  Net changes are queried and applied to the ingestion process each time a synchronization occurs.  This is a highly optimized process given only changed data is queried. &#x20;

Change Data Capture requires the underlying RDBMS have the feature enabled prior setting up the synchronization with Verb.
