Day 19 of 100 Days of ClickHouse®: Managing Users and Roles with RBAC

Short summary

ClickHouse RBAC centralizes permission management by assigning privileges to roles instead of individual users. The tutorial covers creating users, roles, granting SQL privileges, and scaling access control through a layered user→role→privilege→database hierarchy. Best practices include least privilege principle, regular audits, and disabling unused accounts.

• •RBAC replaces individual permission assignments with reusable roles, simplifying management at scale
• •Four-component model: Users connect to roles, roles hold privileges, privileges apply to database objects
• •Best practices: least privilege, regular audits, separate roles for different responsibilities, remove unused access
