This document summarizes a presentation about using Amazon DynamoDB Streams and AWS Lambda for real-time data processing. It discusses how DynamoDB Streams provides a log of item-level changes in DynamoDB tables and how Lambda functions can be triggered by these streams to run custom code. Examples are given of building applications that replicate data, perform auditing, and send notifications in real-time. The presentation includes a demo of setting up cross-region replication and data auditing using DynamoDB Streams and Lambda.
