## AI overview

This article develops a taxonomy of data change events used in Change Data Capture systems such as Debezium. It explains full events, delta events, and ID-only events, along with their contents and use cases including real-time ETL, microservices data exchange, and audit logging.

Table of Contents Full Events Delta Events Id-only Events Change Event Metadata Comparison This post originally appeared on the Decodable blog. All rights reserved. Data change events are at the core of Change Data Capture (CDC) solutions such as Debezium. They describe the changes made to a specific record in a database and allow event consumers to take action based on this information, enabling a wide range of use cases, such as real-time ETL (by propagating the updated data into downstream data stores such as data warehouses, analytics databases, or fulltext search indexes), microservices data exchange, or audit logging.
