YugabyteDB's Change Data Capture (CDC) feature can be used to send data from YugabyteDB to ClickHouse, an open-source column-oriented Online Analytical Processing (OLAP) database. This integration allows users to offload and retain the data for multi-year retention of legal or fiscal compliance, while also enabling real-time dashboards or batch-based reports and feeds for external applications or systems. The CDC architecture is a pull-based approach that reports changes from the database's write-ahead-log (WAL), and it can be integrated with ClickHouse through a Kafka configuration. To configure the sink in ClickHouse, users need to follow specific steps, including installing the server, client, and Kafka table engine, and creating a MergeTree table to store the CDC data ingested from the Kafka topic.
