Introduction to RLS Policies
Grasp the fundamentals of Row-Level Security, its benefits, and how it differs from traditional application-level authorization.
What is Row-Level Security?
Welcome to the world of Row-Level Security (RLS)! RLS is a powerful database feature that allows you to control which individual rows a user can access in a table.
Think of it as a bouncer for each row in your database, deciding who gets to see or interact with it based on rules you define. This is essential for building secure applications where different users need different data views.
App-Level vs. Database-Level Auth
Traditionally, applications filter data after it's retrieved from the database. This means all data is fetched, then your app decides what to show a user.
With Row-Level Security (RLS), the filtering happens directly within the database. The database itself decides which rows a user can even see or modify, before sending them to your application.
