In this video, I am going to show you how to log a user to DynamoDB table when they sign up using Cognito user pool. While Cognito maintains all users in the user pool. There may be use case for the business to maintain users in a table for cross references, validation and reporting.
In order to accomplish this function, I will be using Cognito user pool trigger functionality. I will add a post sign up trigger which will invoke a lambda function once a user has been confirmed after the sign up. This lambda function will retrieve the user from the Cognito event and will store the info in a DynamoDB table.
