Managing Accounts

Scenarios

GeminiDB Redis API provides the enterprise-grade multi-tenant capability. You can add read-only or read/write accounts in your instance to control access to each database to avoid misoperations on data of other tenants. This section describes how to manage accounts.

Precautions

• A maximum of 200 accounts can be created for each GeminiDB Redis instance.
• Account change takes effect 10 seconds later after it is performed.
• If you use a backup to restore data to a new instance, the account information of the original instance will not be inherited.
• The account to be created must meet the requirements in Table 1.

How to Use a New Account to Access a Database

1. Access the database by running auth USER PWD or auth USER:PWD.
2. When you access the database using an SDK on your application, use the value of USER and PWD as the username and password, or use USER:PWD as the password parameter.

   When you access the database by running auth argc , ensure that argc does not contain colons. If an incorrect password contains colons, the returned value is the same as that of auth argc1 argc2.
