Study Notes
Data Governance Model
- Access to data objects can be managed programmatically using SQL commands.
- GRANT command syntax:
GRANT Privilege ON Object TO User. - Example:
GRANT SELECT ON TABLE my_table TO [email protected].
Data Objects
- Objects include various entities which control access scopes:
- CATALOG: Access to the entire data catalog.
- SCHEMA: Access to a specific database.
- TABLE: Access to managed or external tables.
- VIEW: Access to SQL views.
- FUNCTION: Access to named functions.
- ANY FILE: Access to the underlying filesystem.
Privileges
- Different privileges govern user abilities on data objects:
- SELECT: Grants read access to the object.
- MODIFY: Allows adding, deleting, and modifying data in the object.
- CREATE: Enables creation of an object.
- READ_METADATA: Permits viewing of an object and its metadata.
- USAGE: Necessary for performing any actions but has no direct effect on its own.
- ALL PRIVILEGES: Grants all available privileges on an object.
Granting Privileges by Role
- Access privileges can be granted based on user roles:
- Databricks Administrator: Can grant access for all objects within the catalog and filesystem.
- Catalog Owner: Can grant access for all objects in the catalog.
- Database Owner: Can grant access for all objects in a specific database.
- Table Owner: Can grant access specifically for the table, view, or function they own.
More Operations
- Additional commands related to managing data permissions include:
- GRANT: Assigns privileges.
- DENY: Prevents access to specified privileges.
- REVOKE: Removes previously granted privileges.
- SHOW GRANTS: Displays current grants for objects and users.
Data Object Privileges in Databricks
- Databricks implements a data governance model that allows programmatic management of data access.
- Permissions can be granted, denied, or revoked for various data objects using Spark SQL commands.
Types of Data Objects
- Catalog: Controls access to the entire data catalog.
- Schema: Governs access to specific databases.
- Table: Configures permissions for both managed and external tables.
- SQL View: Allows setting permissions for SQL views.
- Named Function: Grants permissions for specific functions.
- Underlying File System: Controlled using the ANY FILE keyword.
Privileges on Data Objects
- SELECT: Grants read access to the object.
- MODIFY: Allows adding, deleting, and modifying data within the object.
- CREATE: Enables the creation of new objects (e.g., creating a new table).
- READ_METADATA: Permits viewing of the object's details and metadata.
- USAGE: An additional requirement to perform actions on database objects without granting actual abilities.
- ALL PRIVILEGES: Combines all the above privileges.
Privilege Management
- Only Databricks administrators or object owners can grant privileges on data objects.
- Database Administrators: Capable of granting access to all objects in the catalog and underlying file system.
- Catalog Owners: Can grant privileges for all objects within the catalog.
- Database Owners: Grant privileges only for objects within their specific database.
- Table Owners: Hold the ability to manage privileges for the specific table.
Operations for Managing Privileges
- Denying and revoking privileges is possible to adjust access as needed.
- Use the SHOW GRANTS operation to display current permissions on objects.
