I’ll have a blog post out in AWS Big Data in a few weeks but the parent is right in that it’s not terribly difficult.

Should take about an hour with testing to get a Pyspark script together to read in a DynamoDB table and write it out to S3.

You’ll then need to crawl the S3 data to add it to your Glue catalog and then you can query it with Athena.
