Creating custom roles in Snowflake - Why You Should Know This

The Big Idea

What if you could control who sees what with just a few clicks instead of endless manual changes?

The Scenario

Imagine you manage access for a growing team using only default roles. Every time someone new joins or changes tasks, you manually adjust permissions one by one.

This feels like juggling many keys without a clear system.

The Problem

Manually assigning permissions is slow and confusing. You risk giving too much or too little access, causing security gaps or blocking work.

It's easy to forget changes or make mistakes that disrupt the team.

The Solution

Creating custom roles lets you bundle exact permissions for specific jobs. Assign these roles to users easily, ensuring everyone has just what they need.

This organized approach saves time and keeps your data safe.

Before vs After

✗ Before

GRANT SELECT ON DATABASE mydb TO USER alice;

✓ After

CREATE ROLE analyst_role; GRANT SELECT ON DATABASE mydb TO ROLE analyst_role; GRANT ROLE analyst_role TO USER alice;

What It Enables

Custom roles unlock simple, secure, and scalable access control tailored to your team's needs.

Real Life Example

A data team creates roles like 'data_analyst' and 'data_engineer' with specific permissions. New hires get the right access instantly by assigning these roles.

Key Takeaways

Manual permission management is slow and risky.

Custom roles group permissions for easy reuse.

This improves security and saves time as teams grow.
