AnalyticDB:Associate with or disassociate from a database account

Prerequisites

A resource group is created. For more information, see Create a resource group.

Background information

AnalyticDB for MySQL Data Lakehouse Edition (V3.0) allows you to associate resource groups with database accounts. This way, compute jobs can be executed based on priority, and core business is not affected by complex computing scenarios or unexpected exceptions. Queries are classified and allocated with appropriate resources to maximize cluster performance. If you did not specify a resource group to execute queries by adding a hint to SQL statements, you can use the resource group that is associated with your database account to execute queries. For more information, see Specify a resource group to execute queries.

Usage notes

You cannot associate the user_default resource group with a database account.

Association rules

• Each database account can be associated with only one resource group, and each resource group can be associated with one or more database accounts.

• If a database account is not associated with a custom interactive resource group, the database account is associated with the default resource group.

• When you delete a resource group, the resource group is disassociated from the database accounts.

• When you delete a database account, the database account is disassociated from the resource group.
