"SnapStart" is a feature of AWS Lambda that aims to significantly reduce "cold start" time. This repository is the example code described in my blog article at https://blog.symphonia.io/posts/2023-01-24_snapstart-how that explains how to use SnapStart. For details on how to build, deploy, and execute this example code please refer to the blog post.
Important: this code was written in January 2023, shortly after SnapStart was released. If you are looking at this code a long time after this date it is likely that certain aspects will have changed, so if in doubt refer to the Lambda documentation here.
The example here came from my book with John Chapin - Programming AWS Lambda . You can find all of the example source code for the book here.
