Time Series Database:Manage user accounts and databases

Last Updated:Feb 19, 2024

This topic describes how to create, modify, and delete a Time Series Database (TSDB) for InfluxDB® database and the user account used to manage the database. This topic also describes how to grant permissions to the user account.

Prerequisites

A Time Series Database (TSDB) for InfluxDB® instance is purchased. For more information, see Create a TSDB for InfluxDB® instance.

Account types

TSDB for InfluxDB® instances support two types of accounts: administrator and standard accounts. You can manage all your accounts and databases in the TSDB console. For more information about permissions that can be granted to each type of account, see Accounts and permissions.

Account type

Description

Administrator account

You can create and manage an administrator account only in the console. You can create only one administrator account for each instance. The administrator account can manage all databases on the instance. The administrator account cannot create or manage other accounts. The administrator account has all permissions on all databases on the instance for which the account is created.

Normal Account

You can create and manage standard accounts only in the console. You can create multiple standard accounts for each instance. A standard account cannot create or manage other accounts. You must grant permissions on specific databases to standard accounts in the console. A standard account can perform read and write operations on the database that this account is authorized to manage.

Manage accounts

Create an account

  1. Log on to the TSDB console.

  2. In the upper-left corner of the console, select the region in which your instance is located.

      Note

      If no databases are created on the instance, create databases before you grant permissions on databases.

    2. Click Authorize > to add the selected databases to the Authorized Databases section.

    3. Grant the permissions on each selected database to the standard account. The following permission types are supported: Read/Write, Read, and Write.

Important

If you create a large number of databases in an instance, data is distributed among the databases, which consumes memory resources and degrades the query performance. We recommend that you create no more than 10 databases in an instance.
