添加资源池

功能介绍

该接口用于添加资源池。

调用方法

请参见如何调用API

URI

PUT /v2/{project_id}/clusters/{cluster_id}/workload/queues
表1 路径参数

参数

是否必选

参数类型

描述

project_id

String

项目ID。获取方法,请参见获取项目ID

cluster_id

String

集群ID。获取方法,请参见获取集群ID

请求参数

表2 请求Body参数

参数

是否必选

参数类型

描述

workload_queue

WorkloadQueue object

资源池对象。

表3 WorkloadQueue

参数

是否必选

参数类型

描述

workload_queue_name

String

资源池名称。以小写字母开头,只包含小写字母、数字、下划线(_),长度3-28个字符。

logical_cluster_name

String

逻辑集群名称。非逻辑集群模式下该字段不填,逻辑集群模式下需指定逻辑集群名称。

workload_resource_item_list

Array of WorkloadResource objects

资源配置队列。

表4 WorkloadResource

参数

是否必选

参数类型

描述

resource_name

String

资源名称。

  • memory:内存资源(%)
  • tablespace:存储资源(MB)
  • activestatements:查询并发
  • cpu_limit:专属限额
  • cpu_share:共享配额
说明:

添加资源池时,所有的资源类型都要填写。其中cpu_limit 仅限在8.1.3以上集群支持。

resource_value

Integer

资源属性值。

  • memory 取值0 ~ 100,其中0表示不管控。
  • tablespace 取值-1 ~ 2147483647,其中-1表示不限制,注:该值取值应参考实际存储资源。
  • activestatements 取值-1 ~ 2147483647 其中-1/0表示不限制。
  • cpu_limit 取值1~99。cpu_limit为0则不约束。
  • cpu_share 取值1~99。cpu_share不填写默认为20。
  • cpu_limit与cpu_share支持同时设置时,以cpu_limit专属限额优先。

响应参数

表5 响应Body参数

参数

参数类型

描述

workload_res_code

Integer

返回状态。

workload_res_str

String

状态描述。

请求示例

添加资源池test11,选择共享配额设为12%,内存资源设为0(不限制),存储资源设为-1(不限制),查询并发设为10:

PUT https://{Endpoint}/v2/89cd04f168b84af6be287f71730fdb4b/clusters/e59d6b86-9072-46eb-a996-13f8b44994c1/workload/queues

    "workload_queue_name": "test11",
    "workload_resource_item_list": [
      {
        "resource_name": "memory",
        "resource_value": "0"
      },
      {
        "resource_name": "tablespace",
        "resource_value": "-1"
      },
      {
        "resource_name": "activestatements",
        "resource_value": "10"
      },
      {
        "resource_name": "cpu_limit",
        "resource_value": 0

      },
      {
        "resource_name": "cpu_share",
        "resource_value": 12
      }
    ],
    "logical_cluster_name": ""
  }
}

响应示例
