Row Level Security(RLS) with Unity Catalog in Databricks
Row-level security (RLS) with Unity Catalog is a powerful feature designed to enhance data governance and security in a multi-tenant environment. It allows you to define fine-grained access controls for your data, ensuring that users can only view or interact with data they are authorized to see based on specified rules.
Key Concepts of Row-Level Security with Unity Catalog:
1. Granular Access Control: You can create policies that restrict access to specific rows in a table based on user attributes or roles. This means that different users can see different data in the same table based on their permissions.
2. Dynamic Filtering: RLS policies can evaluate conditions in real-time when a query is executed. For example, a user might only see data related to their department or region, even though the entire dataset exists in the system.
3. Integration with IAM: Unity Catalog integrates with Identity and Access Management (IAM) systems, allowing you to leverage existing user attributes for defining access policies. This makes implementing RLS more straightforward and consistent with your organization’s security model.
4. Policy Management: You can define, manage, and update RLS policies centrally through the Unity Catalog. This centralized approach…
