If you want to purchase more, go to the Privilege Quotas page. In the Privilege Quota List, find the quota with the Quota Name MaxCompute Subscription Resources Purchase Over The Default Maximum and submit a request. After the request is approved, you can make the purchase.

      • Billing cycle: Billing for the incrementally purchased concurrent connections starts when the upgrade takes effect and ends when the subscription expires.

    • Downgrade policy

      • Scenario: If you have surplus concurrent connections in your exclusive resource group for Data Transmission Service and do not expect to use them in the future, you can downgrade the resource group to release the surplus connections.

        Important

        Promptly release resources that are no longer needed. Otherwise, you will continue to be charged for them, regardless of whether they are used.

      • Refund policy: After a successful downgrade, the resources are released immediately. A refund is issued to your payment account. The refund amount is prorated based on the remaining subscription duration of the released resources.
