DataWorks:Change specifications

Specification change overview

You can upgrade or downgrade the specifications of your current resources. The following table provides details.

Limitations

• Resource group requirements

  You can change the specifications of an exclusive resource group for Data Integration or an exclusive resource group for scheduling only if it is in the Running state.

• Permission requirements

  Only an Alibaba Cloud account or a RAM user that is granted both the AliyunDataWorksFullAccess and AliyunBSSOrderAccess policies can change specifications.

• Billing model limitations

  You cannot change specifications for pay-as-you-go resources.

• Pending order limitations

  If there is an incomplete scaling or change specifications order for an exclusive resource group for scheduling or an exclusive resource group for Data Integration, you cannot perform another scaling or change specifications operation. A dialog box appears, prompting you to go to the Order Center to process the pending order first.

Procedure

The procedure to change specifications is similar for exclusive resource groups for scheduling and for Data Integration. This topic uses an exclusive resource group for scheduling as an example.

1. Go to the Resource Groups page.

   1. Log on to the DataWorks console.

   2. In the left-side navigation pane, click Resource Groups and select the target region.

2. Change Specifications.

   1. On the Exclusive Resource Group tab, find the resource group whose Purpose is Data Scheduling. Hover over the icon in the Operation column and click Change Specifications.

   2. Prepare for the change.

      The Change Specifications page opens.

      1. In the Make Preparations step, review the potential impacts of the operation.

         Note

         This operation affects your running tasks. Review the impacts carefully before you proceed.

         The following table describes the potential impacts.

         Impact	Description
         Task termination	The operation terminates all running tasks on the resource group. DataWorks lists the number and types of running tasks. In the Make Preparations step, you can review the tasks and filter them by owner or workspace to confirm whether terminating them will affect your business.
         Alert triggering	If alert rules are configured for the terminated tasks, this operation may trigger alerts.
         Manual rerun required for some tasks	Some tasks that are terminated by the operation may not be automatically rerun. For example, real-time sync tasks may not resume from their previous offset. In such cases, you must manually restart or rerun the tasks and specify the sync offset. For more information, see Configure real-time synchronization of incremental data from a single table.
         Task delays after a downgrade	If you perform a downgrade operation, you may experience task delays.

      2. Choose whether to automatically rerun terminated production tasks, and then select the I am aware of the impacts of the operation checkbox.

         If you select Yes, DataWorks automatically reruns the terminated production tasks after the change is complete. If you select No, DataWorks does not rerun the tasks.

         Note

         • Production tasks include real-time sync, real-time computing, periodic scheduling, and data backfill tasks in Operation Center. Temporary test tasks that you run in DataStudio are not considered production tasks.

         • Periodic scheduling tasks that are terminated by the platform and those that are automatically rerun after the change create separate entries on the Instance Operation Record page.

      3. Click Next step.

   3. Set new specifications.

      From the New Specifications drop-down list, select the desired specifications. Select the Terms of Service checkbox, and then click Pay Now.

      Note

      You can upgrade or downgrade the specifications of a resource group. Different specifications support different numbers of tasks. For more information, see Number of tasks supported by exclusive resource groups for scheduling with different specifications and Number of tasks supported by exclusive resource groups for Data Integration with different specifications.

   4. Pay for the order.

      Click Go to Payment Page. On the payment page, confirm the order summary and order details, select a payment method, and then click Pay Now. Follow the on-screen instructions to complete the payment.

      Note

      If you cancel the payment, the specification change will not take effect, and your tasks and resource group will not be affected. If the payment fails, we recommend that you go to the Order Center to cancel the order. This prevents issues with future scaling or change specifications operations.

   5. Apply the change.

      After the payment is successful, DataWorks automatically terminates the running tasks on the resource group, changes the specifications, and reruns the terminated production tasks if you selected this option. During this process, the system completes the following sub-steps: Suspend Resource Group, Terminate Tasks, and Apply New Specifications. After the progress reaches 100%, a Change Successful message appears. Click Close. The change process takes some time. If you accidentally close the page, you can check its progress. Go to the Resource Groups page, hover over the icon in the Operation column for the resource group, and click Change Specifications.
