🔗 Understanding Multitenancy in Ash Framework: A Practical Guide

When building multi-customer applications, keeping each customer's data separate and secure is crucial. At its core, multitenancy is about partitioning the data in your database in such a way that one can be confident that data for one a customer won't somehow leak into the data for another customer.

If you are writing in Elixir you have possibly implemented multitenancy, using Ecto. Using Ecto you can use query prefixes or foreign keys to achieve this effect.

Ash has it’s own explicit functionality for elegantly handling multitenancy. In this post, we'll explore how Ash implements multitenancy and when to use different approaches.
