Data Access Control

Kylin provides a rich set of access control features for big enterprise. Start from Kylin 5, every action from user must satisfy both Operation Permission and Data Access Permission, before the action can perform.

  • Operation Permission: Defined at project level, specifies what operations a user can perform within a project. User can have one of the four permissions, from weak to powerful:

    • QUERY: Allows to run query in a project.
    • OPERATION: Allows to operate models, like building, refreshing, and managing Segments. Implies the QUERY permission.
    • MANAGEMENT: Allows to manage models and cubes, like create and edit. Implies the OPERATION permission.
    • ADMIN: Project level administrator permission, allows to manage source tables, and all other operations in a project.

    See Project ACL for more details.

Examples of Permission Check​

To perform an action, user must have operation permission. Below is few examples.

  • To edit a model, user must have the MANAGEMENT permission and have access to all the tables and columns in the model.

Other Notes​

  • The system administrator is not restricted by the data access controls by default, he/she has access to all data.
  • The system does not provide operation permissions at model level yet.
