YugabyteDB's pull-based approach to Change Data Capture (CDC) introduced in 2.13 scans changes from the database's write-ahead-log (WAL), utilizing a dependency on the Debezium connector, Apache Kafka as a queue for change updates, and consumer applications that can consume events from a Kafka queue using sink connectors. CDC enables streaming of row-level changes to downstream applications and systems in an efficient manner, with a focus on scalability and fault tolerance, but currently has limitations such as requiring Debezium and Kafka integration and not supporting YCQL tables or system tables. Future releases aim to address these limitations, including the introduction of push-based CDC, connectors for streaming changes directly from YugabyteDB to cloud storage solutions and gRPC-based CDC client APIs.
