**TLDR:** An approach for tracking data changes in source systems and propagating them to downstream systems in near real time.

<p>Change Data Capture is an architectural approach that improves data collection efficiency by tracking only changes instead of repeatedly copying full datasets. By capturing inserted, updated, and deleted records, it helps keep warehouses, analytics layers, and operational reports more current. CDC offers major benefits in both performance and freshness, especially in large transactional systems. However, when implemented poorly, it can introduce challenging engineering problems such as ordering, idempotency, and late-arriving records.</p>
