Data masking for Row-level security

Why it matters

This feature addresses the need to protect sensitive information by applying data masking as part of row-level security, enhancing privacy and compliance without altering underlying data. It allows users to restrict visibility of sensitive columns based on access policies, improving security controls in multi-tenant or regulated environments.

How to use it

Data masking policies can be defined and managed within ClickHouse Cloud. The clickhouse-client now includes a parser that supports these data masking policies, allowing users to configure and apply masking rules as part of their row-level security setups.
