Scenario
If CUs of a yearly/monthly elastic resource pool cannot meet your service requirements, you can modify the CUs. In this case, you will be charged based on the number of CUs exceeding that of the yearly/monthly elastic resource pool.
For example, you have purchased an elastic resource pool with 64 CUs, and you find that most time data processing needs 128 CUs. You can add 64 CUs to the elastic resource pool and be billed based on a CU/hour basis. To save more, you can scale up your elastic resource pool to 128 CUs and be billed on a yearly/monthly basis for the 128-CU package.
Precautions
Currently, only yearly/monthly elastic resource pools can be scaled.
Scaling Up
- In the navigation pane on the left of the console, choose Resources > Resource Pool.
- Select the elastic resource pool you want and choose More > Modify Specifications in the Operation column.
- In the Modify Specifications dialog page, set Operation to Scale-out and specify the number of CUs you want to add.
- Confirm the changes and click OK.
- Choose Job Management > SQL Jobs to view the status of the SCALE_POOL SQL job.
If the job status is Scaling, the elastic resource pool is scaling up. Wait until the job status changes to Finished.
Scaling Down
By default, the minimum number of CUs is 16. That is, when the specifications of an elastic resource pool are 16 CUs, you cannot scale the pool down.
- In the navigation pane on the left, choose Resources > Resource Pool.
- Select the elastic resource pool you want and choose More > Modify Specifications in the Operation column.
- In the Modify Specifications dialog page, set Operation to Scale-in and specify the number of CUs you want to add.
- Confirm the changes and click OK.
- Choose Job Management > SQL Jobs to view the status of the SCALE_POOL SQL job.
If the job status is Scaling, the elastic resource pool is scaling down. Wait until the job status changes to Finished.
