同步索引配置

对应的配置文件​

{
  "target": {
    "endpoint": "cn-chengdu.log.aliyuncs.com",
    "project": "sls-ml-demo",
    "logstore": "cdn_access_log"
  },
  "destination": [
    {
      "endpoint": "cn-chengdu.log.aliyuncs.com",
      "project": "sls-ml-demo",
      "logstore": "test_temp"
    }
  ]
}

以上配置内容中：

• target字段：对应已经配置好索引的Logstore配置。

• destination字段：对应的是一个数组，数组中的每个元素表示待覆盖索引配置的Logstore配置，其中endpoint表示Logstore所在地域的公网接入点。
