Tutorial: Designing a GraphQL API

This tutorial was created by Shopify for internal purposes. We've created a public version of it since we think it's useful to anyone creating a GraphQL API.

It's based on lessons learned from creating and evolving production schemas at Shopify over almost 3 years. The tutorial has evolved and will continue to change in the future so nothing is set in stone.

But what if you want to iterate over many tonnes of items?

Pluck in batches to the rescue!

This fork works on any orderable primary key not just integers just like http://api.rubyonrails.org/classes/ActiveRecord/Batches.html#method-i-find_in_batches
