MaxCompute:Upgrade or downgrade resource configurations

Last Updated:Feb 22, 2024

This topic describes how to upgrade or downgrade the configurations of a MaxCompute subscription resource package. You can scale out the resources that are allocated to your subscription resource package to handle increased workloads or scale in resources to reduce costs.

Upgrade resource configurations

If the resources that are allocated to your MaxCompute subscription resource package cannot handle the required workloads, you can upgrade the resource configurations to scale out the resources.

  1. Log on to the MaxCompute console. In the top navigation bar, select the region in which your MaxCompute project resides.

  2. In the left-side navigation pane, choose Workspace > Quotas.

  3. On the Quotas page, find the desired quota, click the image..png icon in the Actions column, and then select Upgrade.

  4. On the MaxCompute (Subscription) | Upgrade/Downgrade page, specify the number of compute units (CUs) that you require, read the terms of service, select I have read and agree MaxCompute SLA and I have read and agree Alibaba Cloud Service Agreement - MaxCompute, and then click Buy Now. The fees incurred per upgrade order are calculated based on the following formula:

    • Fees incurred per upgrade order = Fees charged for the remaining period on the subscription project based on the new configuration (Monthly subscription fees charged based on the new configuration/30/24 × Remaining period) - Fees charged for the remaining period on the subscription project based on the previous configuration (Monthly subscription fees charged based on the previous configuration/30/24 × Remaining period)

    • In the preceding formula, the remaining period is from the date when the upgrade takes effect to the date when the subscription expires. The remaining period is measured in hours. If the remaining period is less than one hour, it still must be converted into hours.

  5. On the Purchase page, confirm the order and click Purchase to complete the payment.

    After you complete the payment, you can go to the Orders page to view the details of the order.

    Note

    If the upgrade succeeds, the CUs that are added after the upgrade are automatically included in Default Quota Group. If you want to assign specific CUs that are added after the upgrade from Default Quota Group to another quota groups, log on to MaxCompute Management to perform operations. For more information, see Configure quota groups.

Downgrade resource configurations

You are charged for idle resources. If your actual workloads do not use all of the resources that are allocated to your MaxCompute subscription resource package, you can perform the following steps to release the idle resources to reduce costs:

  1. Log on to the MaxCompute console. In the top navigation bar, select the region in which your MaxCompute project resides.

  2. In the left-side navigation pane, choose Workspace > Quotas.

  3. On the Quotas page, find the desired quota, click the image..png icon in the Actions column, and then select Downgrade.

  4. On the MaxCompute (Subscription) | Downgrade page, specify the number of CUs that you require, read the terms of service, select I have read and agree MaxCompute SLA and I have read and agree Alibaba Cloud Service Agreement - MaxCompute, and then click Buy Now.

    For more information about refund rules for real-time configuration downgrade, see Rules for unsubscribing from resources.

    After you complete the payment, you can go to the Orders page to view the details of the order.

    Note

    If you downgrade resource configurations immediately after an upgrade, you may receive only part of the refund due to one of the following reasons:

    • A discount is applied to the order that you placed when you purchased the resource package. For example, you placed a one-year subscription order. A discount of 15% is applied to the order. Therefore, if the price is USD 154.7, you paid USD 131.5. In this case, the refund is calculated based on the amount after the discount is applied. In this example, the amount after the discount is applied is USD 131.5.

    • A voucher is applied to the order that you placed when you purchased the resource package. In this case, the refund does not include the vouchers that you used.
