How to update python's runtime on AWS lambda function

[rt-slowth]

I heard that version 3.8 of Python on AWS Lambda will be EOL within the year. I would like to update this runtime, but where can I find the CloundFormation stack template.

Hi @rt-slowth, 

Yes, you’re correct. AWS Lambda is ending support for Python 3.8 on October 14, 2024. This follows Python 3.8’s End-Of-Life (EOL) which is scheduled for October 2024.

To update the runtime of your AWS Lambda function, you can modify the Runtime property in your AWS CloudFormation stack template. 

To update the CloudFormation stack, you can use the AWS CLI command aws cloudformation update-stack.

Thanks. I went to AWS Cloudformation stack and edited the template from python 3.8 to 3.12 and updated. I did this for both the workspace stack and the s3 ingestion stack. Will it break anything? Do I need to make any changes in the python code in the template so that there are no problems? If so, what do I need to change?

All the s3 connections I made were made in the last 3 months. Why is Databricks still using python 3.8 in its templates?
