Amazon Keyspaces (for Apache Cassandra) now supports Change Data Capture (CDC) Streams

Amazon Keyspaces (for Apache Cassandra) now supports Change Data Capture (CDC) streams, enabling you to capture row-level changes in your tables in near-real time. CDC streams in Amazon Keyspaces automatically capture insert, update, and delete operations as change events, delivering them in order with automatic deduplication. With CDC streams, you can build event-driven applications and implement use cases such as data analytics, text search, ML training/inference, and continuous data backups for archival.

Amazon Keyspaces (for Apache Cassandra) is a scalable, highly available, and managed Apache Cassandra–compatible database service. Amazon Keyspaces is serverless, so you pay for only the resources that you use and you can build applications that serve thousands of requests per second with virtually unlimited throughput and storage.

CDC streams retain data for up to 24 hours and can scale automatically to match your workload, without requiring any infrastructure management. Additionally, enabling CDC streams will have no impact on your table capacity for compute or storage operations. To consume the CDC stream records, you can use either the Keyspaces Data Streams API or leverage the Kinesis Client Library, a java library that makes it easy to consume and process stream records.

CDC streams are available today in all AWS Commercial and AWS GovCloud (US) Regions where Amazon Keyspaces is available, and you pay only for the change events captured and delivered through your streams. To learn more, visit the Amazon Keyspaces CDC documentation.
