Query proxy settings -

Before you call the DescribeDBProxy operation, make sure that the ModifyDBProxy operation is called to enable the database proxy feature for the instance.

The dedicated proxy feature of ApsaraDB RDS for MySQL provides capabilities such as read/write splitting and short-lived connection optimization. For more information, see What are database proxies?
The database proxy feature of ApsaraDB RDS for PostgreSQL supports read/write splitting. For more information, see What are database proxies?
