How to process DynamoDB updates and define custom triggers

Amazon DynamoDB is a fully managed NoSQL database service, built for highly-scalable systems.

DynamoDB Streams enable event-driven programming with AWS Lambda to define triggers in order to augment your database behavior or implement 3rd-party integrations.

In this Lab, we will learn how to process batches of DynamoDB updates with a Lambda Function. As a simple example, we will use Python to create and sync generated fields. The same mechanism could be used to store operations logs, send SNS notifications, synchronize 3rd-party services, or any custom logic.

If you want to learn the basics of DynamoDB, you can start from our Introduction to DynamoDB Lab.
