Querying Product Flavors

Function

This API is used to query the product flavor (parameter spec_code) required for configuring a new DCS instance. If no search criterion is specified, all product specifications will be queried by default.

URI

GET /v2/{project_id}/flavors

**Table 1** Path Parameters
Parameter	Mandatory	Type	Description
project_id	Yes	String	Project ID.

**Table 2** Query Parameters
Parameter	Mandatory	Type	Description
spec_code	No	String	Product flavor.
cache_mode	No	String	DCS instance type. The options are as follows: single: single-node ha: master/standby cluster: Redis Cluster proxy: Proxy Cluster - ha_rw_split: read/write splitting
engine	No	String	Cache engine. The options are as follows: Redis Memcached
engine_version	No	String	Cache engine version. If the cache engine is Redis, the options are as follows: 3.0 4.0 5.0
cpu_type	No	String	CPU architecture. The options are as follows: x86_64: x86 architecture aarch64: Arm architecture Enumeration values: x86_64 aarch64
capacity	No	String	Cache capacity (GB). For a single-node or master/standby DCS Redis 3.0 instance, the value can be 2, 4, 8, 16, 32, or 64. For a Proxy Cluster DCS Redis 3.0 instance, the value can be 64, 128, 256, 512, or 1024.
