Controlling Access to DataStax Studio

Assign access privileges to roles for DataStax Studio management.

Permissions and syntax

Setting access to DataStax Studio using the following syntax:

Allow access for DataStax Studio use:

GRANT <permission_name>
ON <keyspace_name>.<table_name>
TO <role_name>;

Remove access to DataStax Studio use:

REVOKE <permission_name>
ON <keyspace_name>.<table_name>
FROM <role_name>;

Studio permissions
permission_name	`CQL` command	Description
SELECT	GRANT, and REVOKE	Perform select operations for `CQL` and `Graph` commands in Studio.
EXECUTE	GRANT and REVOKE	Perform execute operations for `REMOTE OBJECT DseClientTool`.
PROXY.EXECUTE	GRANT, and REVOKE	Permission to execute `AlwaysOn Spark SQL` (AOSS) in Studio.

Requirements to GRANT/REVOKE Studio permissions

Roles that manage Studio permissions must have AUTHORIZE on the Studio resources:

Manage permissions for all search indexes:

GRANT AUTHORIZE FOR <permission_name>
ON KEYSPACE <required_keyspaces>
TO <role_name>;

Limit permissions to manage permissions to individual tables:

GRANT AUTHORIZE FOR <permission_name>
ON <required_keyspaces>
TO <role_name>;

Superuser roles have permission to perform any action and therefore do not require explicitly granting authorize permission on Studio resources.

Procedure

A Studio user must have the following SELECT permissions:
```
GRANT SELECT ON system_auth.roles to <studio_role>;
```
This permission allows validation of the CQL role settings for <studio_role>.
A Studio user must have the following SELECT permissions to access DataStax Graph schema views:
```
GRANT SELECT ON system_schema.vertices to <studio_role>;
GRANT SELECT ON system_schema.edges to <studio_role>;
```
These permissions are available by default, unless the system_schema keyspace has had permissions altered.
If DSE Search is used for any data in Studio, the following permission is required to access the search resources and display search indexes:
```
GRANT SELECT ON solr_admin.solr_resources to <studio_role>;
```
The following permissions are required if AlwaysOn SparkSQL is used in Studio, to determine AOSS status, display SparkSQL cached tables in the schema view, identify the current datacenter for the SparkSQL-cached tables, and identify DataStax Graph and AOSS host servers:
```
GRANT SELECT ON dse_analytics.alwayson_sql_info to <studio_role>;
GRANT SELECT ON dse_analytics.alwayson_cache_table to <studio_role>;
GRANT SELECT ON system.local to <studio_role>;
```
Permissions to system.local are available by default, but the role may need permission granted.
Additional permissions required if AlwaysOn Spark SQL is used in Studio identify the current datacenter for the SparkSQL-cached tables, and identify DataStax Graph and AOSS host servers:
```
GRANT EXECUTE ON REMOTE OBJECT DseClientTool to <studio_role>;
```
Lastly, SparkSQL queries do not execute and no error is displayed if this last permission is not set:
```
GRANT PROXY.EXECUTE ON ROLE <studio_role> TO alwayson_sql;
```
