Parameter description

**Table 2** Parameter description
Name	Type	Description
flavors	Array of objects	DB instance specification list. For more information, see Table 3.

**Table 3** flavors field data structure description
Name	Type	Description
engine_name	String	Engine name
type	String	Node type. DDS supports the following types of nodes: mongos shard config replica single
vcpus	String	Number of vCPUs
ram	String	Memory size in GB
spec_code	String	Resource specification code Example: dds.mongodb.c6.xlarge.2.shard NOTE: dds: indicates the DDS service. dds.mongodb: indicates the DDS service. c6.xlarge.2: indicates the node specification. It is a high-memory type. shard: indicates the node type. When querying the specifications, check whether the specifications are of the same series. The specification series includes general-purpose (s6), enhanced (c3), and enhanced II (c6). Example: dds.mongodb.s6.large.4.mongos and dds.mongodb.s6.large.4.config belong to the same specification series. dds.mongodb.s6.large.4.mongos and dds.mongodb.c3.large.4.config are not of the same specification series.
az_status	Object	The status of specifications in an AZ. Its value can be any of the following: normal: indicates that the specification is on sale. unsupported: indicates that the specification is not supported. sellout: indicates that the specification is sold out.

In the example response, az1, az2, and az3 in the az_status field are example values.
