I am using cloudformation template to build a dynamo db ( see below), once the stack builds successfully, I would like to alert/notify/trigger another aws resource, like a lambda function or a step function or a aws data pipeline to start such that I can start populating the dynamo. what is the best way to trigger another process or aws resource once cloudformation stack creation is successful ?

You can setup SNS topic and a lambda function to get events from stack creation. An example of how to do it is given in AWS docs:

• How can I receive an email alert when my AWS CloudFormation stack enters ROLLBACK_IN_PROGRESS status?

You would have to adapt the example and the lambda to suit your needs.
