开启Smart Connect(按需实例)

功能介绍

开启Smart Connect,提交创建Smart Connect节点任务。

当前通过调用API,只支持按需实例创建Smart Connect节点。

调用方法

请参见如何调用API

URI

POST /v2/{project_id}/instances/{instance_id}/connector

表1 路径参数

参数

是否必选

参数类型

描述

project_id

String

项目ID,获取方式请参见获取项目ID

instance_id

String

实例ID。

请求参数

表2 请求Body参数

参数

是否必选

参数类型

描述

specification

String

部署Smart Connect的规格,基准带宽,表示单位时间内传送的最大数据量。请保持和当前实例规格一致。仅老规格实例需要填写。 取值范围:

  • 100MB

  • 300MB

  • 600MB

  • 1200MB

node_cnt

String

Smart Connect节点数量。不能小于2个。 如果不填,默认是2个。

spec_code

String

转储节点规格编码。仅老规格实例需要填写。

响应参数

状态码: 200

表3 响应Body参数

参数

参数类型

描述

job_id

String

任务ID。

connector_id

String

实例转储ID。

请求示例

  • 新规格按需实例的开启Smart Connect,设置Smart Connect节点数量为2。

    POST https://{endpoint}/v2/{project_id}/instances/{instance_id}/connector
    
    {
      "node_cnt" : 2
    }
  • 老规格按需实例的开启Smart Connect,设置Smart Connect节点规格为100MB,节点数量为2。

    POST https://{endpoint}/v2/{project_id}/instances/{instance_id}/connector
    
    {
      "specification" : "100MB",
      "node_cnt" : 2,
      "spec_code" : "kafka.c3.mini.connector"
    }

响应示例

状态码: 200

开启Smart Connect成功。

{
  "job_id" : "7c3ec20c-11de-4df9-acc0-7ef1dea25dfe",
  "connector_id" : "55b78880-9077-4c74-ad5a-6868555f76a4"
