Change data capture (CDC) is a mechanism that helps businesses stay competitive by keeping their data up to date. It identifies and captures changes in data, often automatically delivering detected changes from a source like a database to a target such as a cloud data warehouse. CDC enables organizations to make faster, more informed decisions based on accurate and timely data. Key benefits include improved data governance and compliance, fast and accurate data-driven decision making, enhanced change management and risk assessment, and operational efficiency gains. Fivetran offers CDC as a feature for most of its connectors to applications and all of its connectors to databases, using log-based replication or other mechanisms depending on the database type.
