The Little MongoDB Schema Design Book by Christian Kvalheim

Christian Kvalheim originally wrote the MongoDB Node.js driver in early 2010, and maintained the driver almost singlehandedly until 2017.

If you want to learn how to structure MongoDB schemas for an ecommerce store, a category tree, or a blog that can support hundreds of millions of requests per day, this is the book for you.
