    - When TypeId is a standard architecture, MemSize is the total memory capacity of the instance;
    - When TypeId is a cluster architecture, MemSize is the single-shard memory capacity.
    GoodsNum Yes Integer The number of instances for each purchase. For details, query the sales specifications in all regions through the DescribeProductInfo API.
    Period Yes Integer The purchase duration of an instance
    - If BillingMode is 1, that is, when the billing mode is monthly subscription, you need to set this parameter to specify the duration of the purchased instance. Unit: month. Value range: [1,2,3,4,5,6,7,8,9,10,11,12,24,36].
    - If BillingMode is 0, that is, when the billing mode is pay-as-you-go, you need to set this parameter to 1.
    BillingMode Yes Integer Billing mode. 0: pay-as-you-go
    ZoneId No Integer ID of the AZ where the instance resides. For more information, see Regions and AZs.
    Password No String Password for accessing instances.
    - When the input parameter NoAuth is set to true, password-free access is set for instances and Password does not need to be configured. Otherwise, Password is required.
    - When the instance type parameter TypeId is set to Redis 2.8 Memory Edition (standard architecture) or Redis 4.0, 5.0, or 6.0 Memory Edition (standard architecture or cluster architecture), the password cannot start with a forward slash (/) and should contain 8 to 64 characters, including at least two of the following types: lowercase letters, uppercase letters, digits, and special characters (such as ()`~!@#$%^&*-+=_|{}[]:;<>,.?/).
    - When the instance type parameter TypeId is set to CKV 3.2 Memory Edition (standard architecture or cluster architecture), the password should contain 8 to 30 characters, including only letters and digits.
    VpcId No String VPC ID. If this parameter is not passed in, the classic network will be selected by default. You can query the specific VPC ID in the VPC console.
    SubnetId No String VPC subnet ID. This parameter is not required for the classic network. You can get the specific subnet ID by querying the subnet list in the VPC console.

    DryRun No Boolean An internal parameter used to indicate whether to check when creating an instance.
    - false: Default value. Send a normal request and create an instance if all the requirements are met.
    - true: Send a check request and create no instance.
