Function

This API is used to query all instance specifications under a specified condition.

Constraints

This API supports the following instance types:

GeminiDB Cassandra
GeminiDB Mongo
GeminiDB Influx
GeminiDB Redis

URI

GET https://{Endpoint}/v3.1/{project_id}/flavors

**Table 1** URI parameter
Parameter	Mandatory	Type	Description
project_id	Yes	String	Explanation: Project ID of a tenant in a region. To obtain this value, see Obtaining a Project ID. Constraints: N/A Values: N/A Default value: N/A

**Table 2** Query parameters
Parameter	Mandatory	Type	Description
engine_name	No	String	Explanation: Database type Constraints: N/A Values: cassandra: GeminiDB Cassandra instance specifications are queried. mongodb: GeminiDB Mongo instance specifications are queried. influxdb: GeminiDB Influx instance specifications are queried. redis: GeminiDB Redis instance specifications are queried. Default value: cassandra
mode	No	String	Explanation: Instance type Constraints: N/A Values: CloudNativeCluster: Specifications of instances with cloud native storage are queried. EnhancedCluster: Specifications of GeminiDB Influx cluster (performance-enhanced) instances with classic storage are queried. Default value: If this parameter is not transferred, the specifications of all instances with classic storage are queried.
product_type	No	String	Explanation: Product type Constraints: This parameter is mandatory when you create a GeminiDB Redis instance with cloud native storage. Values: Standard Capacity Default value: N/A
offset	No	Integer	Explanation: Index offset Constraints: N/A Values: The value must be a non-negative number. Default value: If offset is set to N, the query starts from the N+1 piece of data. The default value is 0, which indicates that the query starts from the first piece of data.
limit	No	Integer	Explanation: Maximum of specifications that can be queried Constraints: N/A Values: 1 to 100 Default value: If this parameter is not transferred, the first 100 pieces of specification information can be queried by default.

Request Parameters

**Table 3** Request header parameter
Parameter	Mandatory	Type	Description
X-Auth-Token	Yes	String	Explanation: User token You can obtain the token by calling the IAM API by following Obtaining a User Token Through Password Authentication. Constraints: N/A Values: N/A Default value: N/A
