Domain name for API request: cdb.tencentcloudapi.com.
This API is used to create pay-as-you-go TencentDB instances (which can be source instances, disaster recovery instances, or read-only replicas) by passing in information such as instance specifications, MySQL version number, and instance quantity.
This is an asynchronous API. You can also use the DescribeDBInstances API to query instance details. If the output parameter Status is 1 and the output parameter TaskStatus is 0, the instances have been successfully delivered.
Port, ParamList, or Password is specified in the input parameters, the instance (excluding basic instances) 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

| Memory | Yes | Integer | Instance memory size in MB. Please use the DescribeDBZoneConfig API to query the supported memory specifications. |
| Volume | Yes | Integer | Instance disk size in GB. Please use the DescribeDBZoneConfig API to query the supported disk specifications. |
| EngineVersion | No | String | MySQL version. Valid values: 5.5, 5.6, 5.7, 8.0. You can use the DescribeDBZoneConfig API to query the supported versions. |
| UniqVpcId | No | String | VPC ID. If this parameter is not passed in, the basic network will be selected by default. Please use the DescribeVpcs API to query the VPCs. |
| UniqSubnetId | No | String | VPC subnet ID. If UniqVpcId is set, then UniqSubnetId will be required. Please use the DescribeSubnets API to query the subnet lists. |
| ProjectId | No | Integer | Project ID. If this is left empty, the default project will be used. Please use the DescribeProject API to get the project ID. |
| Zone | No | String | AZ information. By default, the system will automatically select an AZ. Please use the DescribeDBZoneConfig API to query the supported AZs. |
| MasterInstanceId | No | String | Instance ID, which is required and the same as the primary instance ID when purchasing read-only or disaster recovery instances. Please use the DescribeDBInstances API to query the instance IDs. |
| InstanceRole | No | String | Instance type. Valid values: master (primary instance), dr (disaster recovery instance), ro (read-only instance). Default value: master. |
| MasterRegion | No | String | AZ information of the primary instance, which is required for purchasing disaster recovery instances. |
| Port | No | Integer | Custom port. Value range: [1024-65535]. |
| Password | No | String | Sets the root account password. Rule: the password can contain 8-64 characters and must contain at least two of the following types of characters: letters, digits, and special symbols (_+-&=!@#$%^*()). This parameter can be specified when purchasing primary instances and is meaningless for read-only or disaster recovery instances. |
| ParamList.N | No | Array of ParamInfo | List of parameters in the format of ParamList.0.Name=auto_increment&ParamList.0.Value=1. You can use the DescribeDefaultParams API to query the configurable parameters. |
| ProtectMode | No | Integer | Data replication mode. Valid values: 0 (async), 1 (semi-sync), 2 (strong sync). Default value: 0. This parameter can be specified when purchasing primary instances and is meaningless for read-only or disaster recovery instances. |
| DeployMode | No | Integer | Multi-AZ. Valid value: 0 (single-AZ), 1 (multi-AZ). Default value: 0. This parameter can be specified when purchasing primary instances and is meaningless for read-only or disaster recovery instances. |
| SlaveZone | No | String | AZ information of secondary database 1, which is the Zone value by default. This parameter can be specified when purchasing primary instances and is meaningless for read-only or disaster recovery instances. |
| BackupZone | No | String | The availability zone information of Replica 2, which is left empty by default. Specify this parameter when purchasing a source instance in the one-source-two-replica architecture. |
| SecurityGroup.N | No | Array of String | Security group parameter. You can use the DescribeProjectSecurityGroups API to query the security group details of a project. |
| RoGroup | No | RoGroup | Read-only instance information. This parameter must be passed in when purchasing read-only instances. |
| AutoRenewFlag | No | Integer | This field is meaningless when purchasing pay-as-you-go instances. |
| InstanceName | No | String | Instance name. |
| ResourceTags.N | No | Array of TagInfo | Instance tag information. |
| DeployGroupId | No | String | Placement group ID. |
| ClientToken | No | String | A string that is used to guarantee the idempotency of the request, which is generated by the user and must be unique in each request on the same day. The maximum length is 64 ASCII characters. If this parameter is not specified, the idempotency of the request cannot be guaranteed. |
| DeviceType | No | String | Instance resource isolation type. Valid values: UNIVERSAL (general instance), EXCLUSIVE (dedicated instance), BASIC (basic instance). Default value: UNIVERSAL. |
| ParamTemplateId | No | Integer | Parameter template ID. |
| AlarmPolicyList.N | No | Array of Integer | The array of alarm policy IDs. |
| InstanceNodes | No | Integer | The number of nodes of the instance. To purchase a read-only replica or a basic instance, set this parameter to 1 or leave it empty. 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. |
| Cpu | No | Integer | The number of CPU cores of the instance. If this parameter is left empty, the number of CPU cores depends on the Memory value. |
| AutoSyncFlag | No | Integer | Whether to automatically start disaster recovery synchronization. This parameter takes effect only for disaster recovery instances. Valid values: 0 (no), 1 (yes). |
| Parameter Name | Type | Description |
|---|---|---|
| DealIds | Array of String | Short order ID. |
