Account and Authorization

Last updated: 2022-03-02 12:06:29

    Feature Overview

    When there is a large number of database tables in a cluster, you can use various features such as account management (account creation and password management) and account authorization (permission modification and deletion) for refined data permission management.

    Account Management

    1. Log in to the Cloud Data Warehouse console, click a Cluster ID/Name in the cluster list to enter the cluster details page, and switch to the Account Management tab.
    2. On the Account Management tab, you can add and delete cluster system accounts and change passwords. Click Account Management to enter the Account Management page, where Add account is selected for Database Account by default. Set the account type, password, and description as prompted and click OK to create a database account. You can also change passwords and delete accounts by switching accounts.
      Note:

      • Account name rule: it can contain 2–16 lowercase letters, digits, and underscores and must start with a letter and end with a letter or digit.
      • Password rule: it must contain 8–30 (preferably more than 12) characters in at least three of the following types: lowercase letters, uppercase letters, digits, and special characters ()!@#$%^&\*|?>< and cannot start with /.
    3. To delete an account, you must first unbind all its authorizations.

    Account Authorization

    1. Log in to the Cloud Data Warehouse console, click a Cluster ID/Name in the cluster list to enter the cluster details page, and switch to the Account Management tab. Click Account Authorization to authorize the account (binding V-cluster and granting permissions of databases and tables):
      Note:

      • Access Scope: you can grant the permissions of all or certain databases and tables.
      • General Permissions: the query permission is granted by default. You can also grant the setting and insertion permissions as needed (setting permissions: column/index/partition modification, column data modification and deletion, and view/dictionary deletion; insertion permissions: column data insertion and view/dictionary creation).
      • High-Risk Permissions: you can grant table creation/clearing/deletion and database creation/deletion permissions as needed.
    2. You can view account authorization records in the authorization list. To modify or revoke permissions, click the corresponding buttons in the Operation column.
    3. Click Modify Permissions to edit the current account's scope of V-cluster database/table permissions, general permissions, and high-risk permissions.

    Notes

    1. Operations on the account management page involve only SQL accounts but not XML accounts.
    2. You can grant one account the permissions of multiple databases/tables in the V-cluster. Each operation generates an authorization record.
    3. After authorization, you need to modify the password of the default passwordless XML account to avoid potential security risks.
