弹性搜索中索引的Creation_date

Question

我在“索引”设置中添加了索引创建日期，如下所示

"settings" :{ 
  "index" :{ 
     "provided_name":"test",
     "creation_Date":"1493750591836",
     "number_of_shards" : "1",
     "number_of_replicas" : "0"
  }
 }

但是，当我试图发布_template时，会出现以下错误

  "unknown setting [index.creation_date] please check that any required plugins are installed, or check the breaking changes documentation for removed settings"

是否意味着创建时间设置不可用，请澄清。无法找到更多关于这方面的详细信息

你不允许设置那个设置，只允许阅读它。但是，您可以做的是使用mappings._meta部分来存储自定义索引创建日期：

PUT my_index
{
  "settings" :{ 
   "index" :{ 
     "number_of_shards" : "1",
     "number_of_replicas" : "0"
    }
  },
  "mappings": {
    "test": {
      "_meta": { 
        "creation_date":"1493750591836"
      }
    }
  }
}
