Queue Permission Management

Scenario

• You can isolate queues allocated to different users by setting permissions to ensure data query performance.
• The administrator and queue owner have all permissions, which cannot be set or modified by other users.

Operations

1. On the top menu bar of the DLI management console, click Resources > Queue Management.
2. Select the queue to be configured and choose Manage Permissions in the Operation column. The User Permission Info area displays the list of users who have permissions on the queue.

   You can assign queue permissions to new users, modify permissions for users who have some permissions of a queue, and revoke all permissions of a user on a queue.

   • Assign permissions to a new user.
     A new user does not have permissions on the queue.

     1. Click Set Permission on the right of User Permissions page. The Set Permission dialog box is displayed.
     2. Specify Username and select corresponding permissions.
     3. Click OK.

        Table 1 describes the related parameters.
