Change Data Capture (CDC)

Change Data Capture (CDC) is the process of observing changes occurring in a source database (inserts, updates, deletes) and extracting them as a stream of event data. This allows downstream systems, like RisingWave, to react to database modifications in real-time without directly querying the source database frequently. Common tools like Debezium generate CDC streams that RisingWave can ingest and process.
