Chapter 1. Change Data Capture Overview
Technology Preview features are not supported with Red Hat production service-level agreements (SLAs) and might not be functionally complete; therefore, Red Hat does not recommend implementing any Technology Preview features in production environments. This Technology Preview feature provides early access to upcoming product innovations, enabling you to test functionality and provide feedback during the development process. For more information about support scope, see Technology Preview Features Support Scope.
Red Hat Change Data Capture is a distributed platform that monitors databases and creates change event streams. Red Hat Change Data Capture is built on Apache Kafka and is deployed and integrated with AMQ Streams.
Change Data Capture captures row-level changes to a database table and passes corresponding change events to AMQ Streams. Applications can read these change event streams and access the change events in the order in which they occurred.
Change Data Capture has multiple uses, including:
- Data replication
- Updating caches and search indexes
- Simplifying monolithic applications
- Data integration
- Enabling streaming queries
Change Data Capture provides connectors (based on Kafka Connect) for the following common databases:
- MySQL
- PostgreSQL
- SQL Server
- MongoDB
This guide refers to Debezium documentation. Debezium is the open source project for Change Data Capture.

Replaceables
In this document, replaceable text is styled in monospace and italics.
For example, in the following code, you will want to replace my-namespace with the name of your namespace:
sed -i 's/namespace: .*/namespace: my-namespace/' install/cluster-operator/*RoleBinding*.yaml
sed -i 's/namespace: .*/namespace: my-namespace/' install/cluster-operator/*RoleBinding*.yaml
