## AI overview

ClickHouse announces a private preview of a MongoDB Change Data Capture connector in ClickPipes. The connector replicates MongoDB collections to ClickHouse Cloud for real-time analytics, supporting continuous replication and one-time loads from MongoDB Atlas or self-hosted instances. It maps nested documents, arrays, and embedded objects into ClickHouse's native JSON data type.
