The Lambda is included in the DynamoDB exports CloudFormation templates. It's embedded in the file template itself.

Thumbs up on the Glue Dev endpoint. It's been killer. I had trouble setting up a Notebook (I wanted to get fancy with Docker) and I usually use the Python repl link that's provided.

I'm working on a follow up post that removes the Data Pipeline -> Lambda and uses the new Glue DynamoDB integration.

Looking forward to your blog post!
