Domain name for API request: dcdb.intl.tencentcloudapi.com.
This API is used to create a yearly/monthly subscribed TDSQL instance by passing in information such as instance specifications, database version number, and purchased duration.
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: CreateDCDBInstance. |
| Version | Yes | String | Common Params. The value used for this API: 2018-04-11. |
| Region | Yes | String | Common Params. For more information, please see the list of regions supported by the product.

| Zones.N | Yes | Array of String | AZs to deploy shard nodes. You can specify up to two AZs. When the shard specification is 1-source-2-replica, two of the nodes are deployed in the first AZ. The current purchasable AZ needs be pulled through DescribeDCDBSaleInfo API. |
| Period | Yes | Integer | Validity period in months |
| ShardMemory | Yes | Integer | Shard memory size in GB, which can be obtained by querying the instance specification through DescribeShardSpec API. |
| ShardStorage | Yes | Integer | Shard storage size in GB, which can be obtained by querying the instance specification through DescribeShardSpec API. |
| ShardNodeCount | Yes | Integer | Number of nodes in a single shard, which can be obtained by querying the instance specification through DescribeShardSpec API. |
| ShardCount | Yes | Integer | The number of shards in the instance. Value range: 2-8. You can increase up to 64 shards by upgrading your instance. |
| Count | No | Integer | The number of instances to be purchased |
| ProjectId | No | Integer | Project ID, which can be obtained through the DescribeProjects API. If this parameter is not passed in, the instance will be associated with the default project. |
| VpcId | No | String | VPC ID. If this parameter is left empty or not passed in, the instance will be created on the classic network. |
| SubnetId | No | String | VPC subnet ID, which is required when VpcId is specified. |
| DbVersionId | No | String | Database engine version. Valid values: 5.7, 8.0, 10.0, 10.1. |
| AutoVoucher | No | Boolean | Whether to automatically use vouchers. This option is disabled by default. |
| VoucherIds.N | No | Array of String | Voucher ID list. Currently, you can specify only one voucher. |
| SecurityGroupId | No | String | Security group ID |
| InstanceName | No | String | Custom name of the instance |
| Ipv6Flag | No | Integer | Whether IPv6 is supported. Valid values: 0 (unsupported), 1 (supported). |
| ResourceTags.N | No | Array of ResourceTag | Array of tag key-value pairs |
| InitParams.N | No | Array of DBParamValue | List of parameters. Valid values: character_set_server (character set; required); lower_case_table_names (table name case sensitivity; required; 0: case-sensitive; 1: case-insensitive); innodb_page_size (InnoDB data page size; default size: 16 KB); sync_mode (sync mode; 0: async; 1: strong sync; 2: downgradable strong sync; default value: 2). |
| DcnRegion | No | String | DCN source region |
| DcnInstanceId | No | String | DCN source instance ID |
| AutoRenewFlag | No | Integer | Renewal mode. Valid values: 0 (manual renewal, which is the default mode), 1 (auto-renewal), 2 (manual renewal, which is specified by users). If no renewal is required, set it to 0. |
| SecurityGroupIds.N | No | Array of String | Security group IDs in array. This parameter is compatible with the old parameter SecurityGroupId. |
| DcnSyncMode | No | Integer | |
| CpuType | No | String |
| Parameter Name | Type | Description |
|---|---|---|
| DealName | String | Long order ID, which is used to call the DescribeOrders API.The parameter can be used to either query order details or call the user account APIs to make another payment when this payment fails. |
| InstanceIds | Array of String | IDs of the instances you have purchased in this order. If no instance IDs are returned, you can query them with the DescribeOrders API. You can also use the DescribeDBInstances API to check whether an instance has been created successfully.Note: This field may return null, indicating that no valid values can be obtained. |
| 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. |
This example shows you how to create a yearly/monthly subscribed TDSQL instance.
