AWS DynamoDB Streams to Lambda Tutorial in Python | Step by Step Guide

DynamoDB Streams are a powerful feature that allow applications to respond to change on your table's records. Combining this feature with Lambda functions creates a highly scalable and fault tolerant application that can easily respond to record modification. In this video, I show you how to create a Lambda function and define a handler function (in python) that will respond to DynamoDB change events. From there, I define a required IAM role and attach it to the Lambda Function. Afterwards, I create a DynamoDB table and hook up the Lambda trigger. I test the connectivity by making manual updates on my DynamoDB table and confirm the Lambda function is responding appropriately.
