CockroachDB 25.2: Row-Level Security for Enhanced Data Control

CockroachDB's 25.2 release introduces Row-Level Security (RLS), a powerful feature enabling fine-grained access control at the row level within the database. This addresses limitations of traditional table-level permissions, particularly crucial for multi-tenant and multi-region deployments. The article details RLS implementation through multi-tenancy and multi-region use cases, showcasing its benefits in data isolation, regulatory compliance, and simplified application logic. Combining RLS with CockroachDB's Regional By Row (RBR) functionality provides geographically based access control, ensuring compliance with data residency regulations.
