    NodeNum Yes Integer The number of nodes in each replica set. The value range is subject to the response parameter of the DescribeSpecInfo API.
    MongoVersion Yes String Version number. For the specific purchasable versions supported, please see the return result of the DescribeSpecInfo API. The correspondences between parameters and versions are as follows: MONGO_3_WT: MongoDB 3.2 WiredTiger Edition; MONGO_3_ROCKS: MongoDB 3.2 RocksDB Edition; MONGO_36_WT: MongoDB 3.6 WiredTiger Edition; MONGO_40_WT: MongoDB 4.0 WiredTiger Edition; MONGO_42_WT: MongoDB 4.2 WiredTiger Edition.

    Zone Yes String AZ in the format of ap-guangzhou-2. If multi-AZ deployment is enabled, this parameter refers to the primary AZ and must be one of the values of AvailabilityZoneList.
    ClusterType Yes String Instance type. REPLSET: replica set; SHARD: sharding cluster
    VpcId No String VPC ID. If this parameter is not set, the basic network will be selected by default
    SubnetId No String VPC subnet ID. If VpcId is set, then SubnetId will be required
    Password No String Instance password, which must contain 8 to 16 characters and comprise at least two of the following types: letters, digits, and symbols (!@#%^*()). If it is left empty, the password is in the format of "instance ID+@+root account UIN". For example, if the instance ID is "cmgo-higv73ed" and the root account UIN "100000001", the instance password will be "cmgo-higv73ed@100000001".
    ProjectId No Integer Project ID. If this parameter is not set, the default project will be used
    Tags.N No Array of TagInfo Instance tag information
    Clone No Integer Instance type. Valid values: 1 (primary instance), 2 (temp instance), 3 (read-only instance), 4 (disaster recovery instance), 5 (cloned instance).
    Father No String Parent instance ID. It is required if the Clone is 3 or 4.
    SecurityGroup.N No Array of String Security group.
    RestoreTime No String The point in time to which the cloned instance will be rolled back. This parameter is required for a cloned instance. The point in time in the format of 2021-08-13 16:30:00 must be within the last seven days.

Nodes of a multi-AZ instance must be deployed across three AZs. 2. To ensure a successful cross-AZ switch, you should not deploy most of the nodes to the same AZ. (For example, a three-node sharded cluster instance does not support deploying two or more nodes in the same AZ.) 3. MongoDB 4.2 and later versions do not support multi-AZ deployment. 4. Read-Only and disaster recovery instances do not support multi-AZ deployment. 5. Instances in the classic network do not support multi-AZ deployment.
