• Before calling an API, you need to understand the API in Authentication.
• Before calling this API, obtain the required region and endpoint.

URI

• URI format

  GET https://{Endpoint}/v3/{project_id}/flavors/{database_name}?version_name={version_name}

• Parameter description

  Table 1 Parameter description

  Name	Mandatory	Description
  project_id	Yes	Specifies the project ID of a tenant in a region. For details about how to obtain the project ID, see Obtaining a Project ID.
  database_name	Yes	Specifies the DB engine name. Its value can be any of the following and is case-insensitive: MySQL PostgreSQL SQLServer
  version_name	No	Specifies the database version. For details about how to obtain the database version, see section Querying Version Information About a DB Engine. For details about the version, see DB Engines and Versions.
  spec_code	No	Specifies the specification code. NOTICE: For Microsoft SQL Server, Only 2022_EE, 2019_EE and 2017_EE support the creation of read replicas and do not support the creation of single DB instances. The format of the specification code is: {spec code}{instance mode}. spec code can be obtained from DB Instance Classes. instance mode can be any of the following: For single DB instances, the value is null. Example spe_code: rds.mysql.n1.xlarge For primary/standby DB instances, the value is .ha. Example spe_code: rds.mysql.n1.xlarge.ha For read replicas, the value is .rr. Example spe_code: rds.mysql.n1.xlarge.rr

  Table 3 flavors field data structure description

  Name	Type	Description
  vcpus	String	Indicates the CPU size. For example, the value 1 indicates 1 vCPU.
  ram	Integer	Indicates the memory size in GB.
  id	String	Indicates the specification ID, which is unique.
  spec_code	String	Indicates the resource specification code. Use rds.mysql.n1.xlarge.rr as an example. rds: indicates the RDS product. mysql: indicates the DB engine. n1.xlarge: indicates the high memory performance specifications. rr: indicates the read replica (.ha indicates primary/standby DB instances).
  version_name	Array	Indicates the database version. MySQL databases support 5.6, 5.7, and 8.0. PostgreSQL databases support 9.5, 9.6, 10, 11, 12, 13, 14 and 15.

  instance_mode	String	Indicates the DB instance type. Its value can be any of the following: ha: indicates primary/standby DB instances. replica: indicates read replicas. single: indicates single DB instances.
  az_status	Map<String, String>	Indicates the specification status in an AZ. Its value can be any of the following: normal: indicates that the specifications in the AZ are available. unsupported: indicates that the specifications are not supported by the AZ. sellout: indicates that the specifications in the AZ are sold out.
