Constraints

None

URI

GET /v2/{project_id}/flavors?engine_id={engine_id}?offset={offset}&limit={limit}

**Table 1** Path parameters
Parameter	Mandatory	Type	Description
project_id	Yes	String	Project ID of a tenant in a region

**Table 2** Query parameters
Parameter	Mandatory	Type	Description
engine_id	Yes	String	Engine ID, which can be obtained by calling the API for querying DDM engine information.
offset	No	Integer	Index offset. The query starts from the next piece of data indexed by this parameter. The value is 0 by default. The value must be a positive integer.
limit	No	Integer	A maximum of node classes to be queried. Value range: 1 to 128. If the parameter value is not specified, 10 node classes are queried by default.

Request Parameters

**Table 3** Request header parameters
Parameter	Mandatory	Type	Description
X-Auth-Token	Yes	String	User token. It can be obtained by calling an IAM API. The value of X-Subject-Token in the response header is the user token.

Response Parameters

Status code: 200

**Table 4** Response body parameters
Parameter	Type	Description
computeFlavorGroups	Array of ComputeFlavorGroupsInfo objects	Compute flavor information

**Table 5** ComputeFlavorGroupsInfo
Parameter	Type	Description
groupType	String	Compute resource architecture type. The value can be x86 or ARM.
computeFlavors	Array of ComputeFlavors objects	Compute flavors
offset	Integer	Which page the server starts returning items
limit	Integer	Number of records displayed on each page
total	Integer	Total number of compute flavors

**Table 6** ComputeFlavors
Parameter	Type	Description
id	String	Flavor ID
typeCode	String	Resource type code
code	String	VM flavor types recorded in DDM
iaasCode	String	VM flavor types recorded by the IaaS layer
cpu	String	Number of CPUs
mem	String	Memory size, in GB
maxConnections	String	Maximum number of connections
serverType	String	Compute resource type
architecture	String	Compute resource architecture type. The value can be x86 or ARM.
azStatus	Map<String,String>	Status of the AZ where node classes are available. The key is the AZ ID and the value is the AZ status. The value can be: normal: indicates that the node classes in the AZ are available. unsupported: indicates that the node classes are not supported by the AZ. sellout: indicates that the node classes in the AZ are sold out.
regionStatus	String	Region status
groupType	String	Compute resource architecture type. The value can be x86 or ARM.
dbType	String	Engine type
extendFields	Map<String,String>	Extension field for storing AZ information

Status code: 400
