Parameter description

**Table 1** Parameter description
Name	Mandatory	Type	Description
project_id	Yes	String	Specifies the project ID of a tenant in a region.
id	No	String	Specifies the instance ID, which can be obtained by calling the API for querying instances and details. If you do not have an instance, you can call the API used for creating an instance.
name	No	String	Specifies the DB instance name. If you use asterisk () at the beginning of the name, fuzzy search results are returned. Otherwise, the exact results are returned. NOTE: The asterisk () is a reserved character in the system and cannot be used alone.
mode	No	String	Specifies the instance type. Sharding indicates the cluster instance. ReplicaSet indicate the replica set instance. Single indicates the single node instance.
datastore_type	No	String	Specifies the database type. The value is DDS-Community.
vpc_id	No	String	Specifies the VPC ID. To obtain this parameter value, use either of the following methods: Method 1: Log in to VPC console and view the VPC ID on the VPC details page. Method 2: See the "Querying VPCs" section in the Virtual Private Cloud API Reference.
subnet_id	No	String	Specifies the network ID of the subnet. To obtain this parameter value, use either of the following methods: Method 1: Log in to VPC console and click the target subnet on the Subnets page. You can view the network ID on the displayed page. Method 2: See the "Querying Subnets" section in the Virtual Private Cloud API Reference.
offset	No	Integer	Specifies the index position. The query starts from the next instance creation time indexed by this parameter under a specified project. If offset is set to N, the resource query starts from the N+1 piece of data. The value must be greater than or equal to 0. If this parameter is not transferred, offset is set to 0 by default, indicating that the query starts from the latest created DB instance.
limit	No	Integer	Specifies the maximum allowed number of DB instances. The value ranges from 1 to 100. If this parameter is not transferred, the first 100 DB instances are queried by default.
tags	No	String	Query based on the instance tag key and value. {key} indicates the tag key, and {value} indicates the tag value. A maximum of 20 key-value pairs are supported. The key cannot be empty or duplicate, but the value can be empty. To query instances with multiple tag keys and values, separate key-value pairs with commas (,).
