Snowflake is a cloud-based data warehousing solution that enables businesses to store and analyze data at scale. One of the key features of Snowflake is its row-level security (RLS) functionality, which provides granular access controls to data stored within the platform. This functionality enables organizations to implement sophisticated security policies that restrict access to sensitive data per-row basis.
In this blog, we will explore the Snowflake row-level security feature in detail, including how it works, its benefits, and how to implement it with an example.
Note: This feature is available in the snowflake enterprise edition.

Snowflake row-level security works by allowing administrators to create policies that determine which rows of data a given user can access. These policies are defined using logical expressions that evaluate true or false for each row in a given table. For example, an administrator might define a policy that grants access to all rows in a table where the value of a particular column matches a specific value.
When a user attempts to access a table that has a row-level security policy applied to it, Snowflake evaluates the policy for each row in the table to determine…
