DDS.CommunityReplicaSetOrSingle
Element Description
The DDS.CommunityReplicaSetOrSingle element is used to create a replica set instance or a single-node instance.
A replica set consists of three nodes: primary, secondary, and hidden. The three-node architecture is automatically set up, and the three nodes automatically synchronize data with each other to ensure data reliability. The single-node architecture contains only one node. The node can be directly accessed.

Database instance type Type: string Value Description: ReplicaSet or Single Default: ReplicaSet Value Constraint: The value can only be ReplicaSet or Single. Suggestion: Set the value based on specifications and requirements. |
subnetId |
Yes |
ID of the subnet to which the instance belongs Type: HuaweiCloud.VPC.Subnet.Id Value Description: Supports the use of an existing or new subnet ID. To use a new subnet ID, you need to define the subnet object in the template and establish the dependency relationship. You are advised to connect the VPC.Subnet to automatically establish the dependency relationship. Value Constraint: The subnet must correspond to the VPC. Suggestion: 1. Use the get_input function to import this field. The value is automatically selected on the AOS page. 2. Use the get_reference function to obtain the VPC.Subnet element created by the stack. The element is automatically specified when you use the designer to establish the dependency relationship. 3. Obtain the created subnet ID on the VPC page. See https://console.huaweicloud.com/vpc |
dataStore |
Yes |
Database information Type: DDS.DDSCommunity.DataStore Default: {u'storageEngine': u'wiredTiger', u'dbtype': u'DDS-Community', u'version': u'4.0'} Suggestion: Select the dataStore field in the component part, and then fill in the field based on prompts. |
