Description

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, you will learn how to process batches of DynamoDB updates with a Lambda Function. As a simple example, Python is used 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.

Learning Objectives

Upon completion of this Lab you will be able to:

Enable Streams on DynamoDB services
Create an AWS Lambda Function that triggers off of DynamoDB table changes

Lab Prerequisites

You should be familiar with:

Basic concepts of DynamoDB (To learn more on the basics of DynamoDB, start from the Lab Introduction to DynamoDB)
Experience developing in Python is beneficial but not required
How to create a Lambda Function
