Intermediate SQL with Ecto - Dennis Beatty
Ecto makes it incredibly easy to work with slightly more advanced SQL features. There are several gotchas to dealing with some of these though. I have discovered some of these while maintaining a database of scraped data and a basic recipe app. By recreating these in a simple manner, we can easily understand the need for upserts and fragments. We will be able to explore the handling of many-to-many relationships (including a discussion of put_assoc vs cast_assoc) and talk about the best way to efficiently insert and update high volumes of records.

This is the best coverage of upserts in Ecto that I’ve seen. It really helped me out on a feature I had in progress.
