Thanks Marius for the response and appreciate all the good feedback. Idea around this article is to show how we can leverage the power of lambda extensions to create a caching layer for any configuration data (hosted in AWS or on-prem). After writing this article I was able to make this more generic like a plugin, where you can keep adding new services. If you are interested refer to this article: https://aws.amazon.com/blogs/compute/caching-data-and-configuration-settings-with-aws-lambda-extensions/ we have open sourced the code in aws-samples repo (written in golang). https://github.com/aws-samples/aws-lambda-extensions/tree/main/cache-extension-demo. Currently the sample covers "AWS parameter store, secrets manager and dynamodb" but its much easy to extend to other services. Feel free to reach out to me if you have any further question, happy to help. Thanks.
