This API only supports: ap-bangkok, ap-beijing, ap-chengdu, ap-chongqing, ap-guangzhou, ap-hongkong, ap-jakarta, ap-nanjing, ap-seoul, ap-shanghai, ap-shanghai-fsi, ap-shenzhen-fsi, ap-singapore, ap-tokyo, eu-frankfurt, na-ashburn, na-siliconvalley. |
| ShardMemory | Yes | Integer | Shard memory in GB, which can be obtained through the DescribeShardSpec API. |
| ShardStorage | Yes | Integer | Shard capacity in GB, which can be obtained through the DescribeShardSpec API. |
| ShardNodeCount | Yes | Integer | The number of nodes per shard, which can be obtained through the DescribeShardSpec API. |
| ShardCount | Yes | Integer | The number of shards in the instance. Value range: 2-8. Upgrade your instance to have up to 64 shards if you require more. |
| 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 |
| ShardCpu | No | Integer | The number of CPU cores per shard, which can be obtained through the DescribeShardSpec API. |
| DbVersionId | No | String | Database engine version. Valid values: 5.7, 8.0, 10.0, 10.1. |
| Zones.N | No | Array of String | AZs to deploy shard nodes. You can specify up to two AZs. |
| 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 |
| DcnRegion | No | String | If you create a disaster recovery instance, you need to use this parameter to specify the region of the associated source instance so that the disaster recovery instance can sync data with the source instance over the Data Communication Network (DCN). |
| DcnInstanceId | No | String | If you create a disaster recovery instance, you need to use this parameter to specify the ID of the associated source instance so that the disaster recovery instance can sync data with the source instance over the Data Communication Network (DCN). |
| 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). |
| RollbackInstanceId | No | String | ID of the instance to be rolled back |
| RollbackTime | No | String | Rollback time, such as "2021-11-22 00:00:00". |
| SecurityGroupIds.N | No | Array of String | Array of security group IDs (this parameter is compatible with the old parameter SecurityGroupId) |
| DcnSyncMode | No | Integer | |
| CpuType | No | String |
| Parameter Name | Type | Description |
|---|---|---|
| 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. |
| FlowId | Integer | Task ID, which can be used to query the creation progress |
| DealName | String | Order ID, which is used for calling 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. |
| 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.
