Domain name for API request: cdb.tencentcloudapi.com.
This API is used to create a pay-as-you-go TencentDB instance (which can be a master, disaster recovery, or read-only instance) by passing in information such as instance specifications, MySQL version number, and quantity.
This is an async API. You can also use the DescribeDBInstances API to query the instance details. If the Status value of an instance is 1 and TaskStatus is 0, the instance has been successfully delivered.
Port, ParamList, or Password is set in the input parameters, the instance will be initialized.A maximum of 20 requests can be initiated per second for this API.
Note: This API supports Finance regions. If the common parameter Region is a Finance region, a domain name with the Finance region needs to be specified, for example: cdb.ap-shanghai-fsi.tencentcloudapi.com
