| InstanceName | No | String | Instance name. Only Chinese characters, letters, digits, underscores (_), and delimiters (-) are supported, with a length of 128 characters. When database instances are purchased in batches, the automatic ascending feature is supported through the custom naming pattern string and numeric suffix to set instance names efficiently. - Basic mode: prefix + automatic ascending number (starting from 1 by default). Only a custom instance name prefix is required for lnstanceName. For example, it can be set to cmgo. If the purchase quantity is set to 5, after purchase, the instances will be sequentially named cmgo1, cmgo2, cmgo3, cmgo4, and cmgo5, respectively. - Custom starting number mode: prefix + {R:x} (x is the custom starting number). Prefix{R:x} is required for InstanceName. For example, cmgo{R:3}. If the purchase quantity is set to 5, the instance names will be sequentially named cmgo3, cmgo4, cmgo5, cmgo6, and cmgo7. - Composite pattern string: prefix 1{R:x} + prefix 2{R:y}+ ⋯ + fixed suffix, where x and y are the starting numbers of each prefix. A composite pattern string is required for instanceName. For example, cmgo{R:10}_node{R:12}_db. If the batch purchase quantity is set to 5, the instances will be sequentially named cmgo10_node12_db, cmgo11_node13_db, cmgo12_node14_db, cmgo13_node15_db, and cmgo14_node16_db. |
| AvailabilityZoneList.N | No | Array of String | Specifies the list of AZs during multi-AZ deployment of TencentDB for MongoDB instances. - For instances in multi-AZ deployment mode, the Zone parameter specifies the primary AZ, and AvailabilityZoneList specifies all AZs, including the primary AZ. Format: [ap-guangzhou-2,ap-guangzhou-3,ap-guangzhou-4]. - The DescribeSpecInfo API can be called to obtain AZs planned for TencentDB for MongoDB instances in different regions, helping you specify valid AZs. - Nodes in multi-AZ deployment mode can only be deployed in 3 different AZs. Deploying most nodes of a cluster in the same AZ is not supported. For example, a 3-node cluster does not support deploying 2 nodes in the same AZ. |
| MongosCpu | No | Integer | Number of Mongos node CPU cores. Valid values: 1, 2, 4, 8, and 16. This parameter is required during sharded cluster instance purchase. |
| MongosMemory | No | Integer | Mongos node memory size. - This parameter is required during sharded cluster instance purchase. - Unit: GB. 1-core 2 GB, 2-core 4 GB, 4-core 8 GB, 8-core 16 GB, and 16-core 32 GB are supported. |
| MongosNodeNum | No | Integer | Number of Mongos nodes. This parameter is required during sharded cluster instance purchase. - For instances in single-AZ deployment mode, the value range is [3,32]. - For instances in multi-AZ deployment mode, the value range is [6,32]. |
| ReadonlyNodeNum | No | Integer | Number of read-only nodes. Value ranges: [0,5]. |
| ReadonlyNodeAvailabilityZoneList.N | No | Array of String | Array of AZs of read-only nodes. This parameter is required for instances in multi-AZ deployment mode when ReadonlyNodeNum is not set to 0. |
| HiddenZone | No | String | AZ where the hidden node resides, which is required in cross-AZ instance deployment. |
| ParamTemplateId | No | String | Parameter template ID. - A parameter template is a collection of predefined parameter values that can be used to quickly configure new MongoDB instances. Proper use of parameter templates can significantly enhance the deployment efficiency and operational performance of the database. - The DescribeDBInstanceParamTpl API can be called to obtain the parameter template ID. Select the parameter template ID corresponding to the instance version and architecture. |
| Parameter Name | Type | Description |
|---|---|---|
| DealId | String | Order ID |
| InstanceIds | Array of String | List of IDs of the created instances |
| 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. |
