CreateDBInstance

Last updated: 2024-01-30 10:26:10

    1. API Description

    Domain name for API request: cdb.tencentcloudapi.com.

    This API is used to create a monthly subscribed TencentDB instance (which can be a source, disaster recovery, or read-only instance) by passing in information such as instance specifications, MySQL version number, purchased duration, and quantity.

    This is an asynchronous API. You can also use the DescribeDBInstances API to query the instance details. If the output parameter Status is 1 and the output parameter TaskStatus is 0, the instance has been successfully delivered.

    1. You can use the DescribeDBZoneConfig API to query the purchasable instance specifications, and then use the DescribeDBPrice API to query the prices of the purchasable instances.
    2. You can create up to 100 instances at a time, with an instance validity period of up to 36 months.
    3. MySQL v5.5, v5.6, v5.7, and v8.0 are supported.
    4. Source instances, read-only instances, and disaster recovery instances can be created.
    5. If Port, ParamList, or Password is specified in the input parameters, the instance (excluding basic instances) will be initialized.
    6. If Port, ParamTemplateId, or AlarmPolicyList is specified in the input parameters, you need to update your SDK to the latest version.

    A maximum of 20 requests can be initiated per second for this API.

    We recommend you to use API Explorer
    Try it
    API Explorer provides a range of capabilities, including online call, signature authentication, SDK code generation, and API quick search. It enables you to view the request, response, and auto-generated examples.

    ResourceTags.N No Array of TagInfo Instance tag information
    DeployGroupId No String Placement group ID
    ClientToken No String A string unique in 48 hours, which is supplied by the client to ensure that the request is idempotent. Its maximum length is 64 ASCII characters. If this parameter is not specified, the idempotency of the request cannot be guaranteed.

To purchase a three-node instance, set this parameter to 3 or specify the BackupZone parameter. If the instance to be purchased is a source instance and both BackupZone and this parameter are left empty, the value 2 will be used, which indicates the source instance will have two nodes.
