This project showcases how to introduce idempotency to AWS lambda handlers by using a DynamoDB table. Most of the hard work is done by Powertools for AWS Lambda and Serverless.
Make sure that NPM and Poetry are installed on your system. Next, clone this repository and install the necessary node packages via npm install.
Deploy this project using Serverless with
sls deploy- The TableName property of the defined DynamoDB table needs to match the one referenced in
app.py. This could be improved by introducing an environment variable taken from the serverless file.
