A way of recording each change made to a database as it happens, so other systems can act on the new data without reloading the whole database.
Change Data Capture (CDC) lets enterprise databases stream changes in real time. Instead of running large nightly batch jobs to update a Vector Database, CDC detects when a record changes and pushes that change to the embedding pipeline, so the data the AI retrieves stays in step with live operations.
