Domain name for API request: cdb.intl.tencentcloudapi.com.
This API is used to enable CPU Elastic Scaling, including one-time manual scale-out and automatic elastic scaling.
A maximum of 20 requests can be initiated per second for this API.
The following request parameter list only provides API request parameters and some common parameters. For the complete common parameter list, see Common Request Parameters.
| Parameter Name | Required | Type | Description |
|---|---|---|---|
| Action | Yes | String | Common Params. The value used for this API: StartCpuExpand. |
| Version | Yes | String | Common Params. The value used for this API: 2017-03-20. |
| Region | Yes | String | Common Params. For more information, please see the list of regions supported by the product. |
| InstanceId | Yes | String | Instance ID, which can be obtained through the DescribeDBInstances API. |
| Type | Yes | String | Scale-out type supports auto-scaling and custom scaling. Description: 1. auto means automatic scaling. 2. manual means custom scaling with immediate effect. 3. timeInterval means custom scaling by time. 4. period means custom scaling by cycle. |
| ExpandCpu | No | Integer | Number of CPU cores for scale-out during customization. Description: 1. This parameter is required when Type is set to manual, timeInterval, or period. 2. The maximum number of CPU cores to increase is the current instance's CPU core number. For example, an 8-core 16GB instance can scale out up to 8 CPU cores, with a range of 1 - 8. |
| AutoStrategy | No | AutoStrategy | Automatic scale-out policy. This parameter is required when Type is set to auto. |
| TimeIntervalStrategy | No | TimeIntervalStrategy | Scaling policy by time period. Description: When Type is timeInterval, TimeIntervalStrategy is required. |
| PeriodStrategy | No | PeriodStrategy | Scale by cycle. Description: When Type is period, PeriodStrategy is required. |
| Parameter Name | Type | Description |
|---|---|---|
| AsyncRequestId | String | Asynchronous Task ID. Call the API DescribeAsyncRequest and input the ID to query the task execution progress. |
| RequestId | String | The unique request ID, generated by the server, will be returned for every request (if the request fails to reach the server for other reasons, the request will not obtain a RequestId). RequestId is required for locating a problem. |
The customer can call this API for one-time instance expansion of the CPU core number.
