DynamoDB Change Data Capture: A Definitive Guide

Change Data Capture (CDC) is a method used in modern data systems for tracking changes in databases, ensuring effective communication between different parts of the system and maintaining accurate and current data. CDC can be useful for quickly moving data to other locations like data warehouses for analysis. DynamoDB, an Amazon service, supports CDC through Kinesis Data Streams and DynamoDB Streams. The choice between these two methods depends on factors such as the duration of data storage, speed of data processing, real-time updates, and specific application requirements. Implementing CDC with DynamoDB involves setting up a database, enabling Amazon Kinesis Data Streams, configuring Kinesis with Amazon S3, running an application to interact with the database, testing CDC with Kinesis and S3, and reading files from the S3 bucket.
