Querying Database Specifications¶
Function¶
This API is used to query all instance specifications under a specified condition.
URI¶
URI format
GET https://{Endpoint}/v3.1/{project_id}/flavors?engine_name={engine_name}&engine_version={engine_version}&offset={offset}&limit={limit}
Parameter description
Table 1 Parameter description¶ Name
Mandatory
Description
project_id
Yes
Specifies the project ID of a tenant in a region.
engine_name
No
Specifies the database type. The value is DDS-Community.
engine_version
No
DB version number. To obtain this value, see Querying Database Version Information.
offset
No
Index offset.
If offset is set to N, the resource query starts from the N+1 piece of data. The default value is 0, indicating that the query starts from the first piece of data.
The value must be a positive integer.
limit
No
Maximum number of specifications that can be queried
Value range: 1-100
If this parameter is not transferred, the first 100 pieces of specification information can be queried by default.

Table 2 Parameter description¶ Name
Type
Description
flavors
Array of objects
Indicates the DB instance specifications information list. For more information, see Table 3.
total_count
Integer
Total number of records
Table 3 flavors field data structure description¶ Name
Type
Description
engine_name
String
Indicates the engine name.
type
String
Indicates the node type. DDS contains the following types of nodes:
mongos
shard
config
replica
single
vcpus
String
Indicates the number of vCPUs.
ram
String
Indicates the memory size in gigabyte (GB).
spec_code
String
Indicates the resource specification code.
Example: dds.mongodb.s2.xlarge.4.shard
Note
dds.mongodb: indicates the DDS service.
s2.xlarge.4: indicates the performance specification, which is high memory.
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).
az_status
Object
Indicates the status of specifications in an AZ. Its value can be any of the following:
normal: indicates that the specifications are on sale.
unsupported: indicates that the DB instance specifications are not supported.
sellout: indicates the specifications are sold out.
Note
ReplicaSet flavors supports cross AZ creation in case "eu-de-01,eu-de-02,eu-de-03": "normal".
engine_versions
Array of strings
Database versions
For example, DDS mongos node, {"3.2", "3.4", "4.0", "4.2", "4.4"}
Note
The value of az_status is used as an example.
