将include_type_name放在config.exs中的位置

2024-05-03 • 问答

我想从我的elixir config.exs文件创建一个Elasticsearch 7.x索引：

config :app_core,App.Tools.ElasticsearchCluster,url: System.get_env("ELASTIC_HOST"),# username: "username",# password: "password",api: Elasticsearch.API.HTTP,json_library: Poison,indexes: %{
    indie: %{
      settings: "priv/elasticsearch/indies.json",store: App.Tools.ElasticSearch.Indie.Store,sources: [App.Data.Schema.Indie],bulk_page_size: 5000,bulk_wait_interval: 15_000
    }
  }

priv/elasticsearch/indies.json以

开头

{
  "mappings": {
     "_doc":    {
      "properties": {
        "category" : {
          "type": "nested","properties" : {

但是，当我尝试创建索引时，出现错误

"The mapping definition cannot be nested under a type [_doc] unless include_type_name is set to true."

有人知道如何在我引用的上下文中解决此问题（将其置于特定查询的前面是行不通的）吗？

应阿萨尔·阿兹兰（Assael Azran）的要求，以下是完整的indies.json：

{
  "mappings": {
     "_doc": {
      "properties": {
        "category" : {
          "type": "nested","properties" : {
            "all_parents" : {
              "type" : "keyword"
            },"direct_parent" : {
              "type" : "keyword"
            },"paths" : {
              "type" : "keyword"
            }
          }
        },"slug": {
          "type": "keyword"
        },"parent_id": {
          "type": "integer","index": false
        },"images": {
          "type": "nested","properties": {
            "indie_url": {
              "type": "text","index": false
            }
          }
        },"tenant": {
          "type": "keyword"
        },"suggest_keywords": {
          "type": "completion","contexts": [
            {
                "name": "tenant","type": "category"
            }
          ]
        },"name": {
          "type": "text"
        },"description": {
          "type": "text","updated_at": {
          "type": "date"
        },"string_facet": {
          "type": "nested","properties": {
            "id": {
              "type": "keyword"
            },"value": {
              "type": "keyword"
            }
          }
        },"number_facet": {
          "type": "nested","value": {
              "type": "double"
            }
          }
        }
      }
    }
  }
}

版本7.x不再支持映射类型。

Elasticsearch 7.x 不建议在请求中指定类型。例如，索引文档不再需要文档类型。对于显式ID，新的索引API是PUT {index} / _ doc / {id}，对于自动生成的ID，则是POST {index} / _ doc。请注意，在7.0中，_doc是路径的永久部分，它表示端点名称而不是文档类型。索引创建，索引模板和映射API中的include_type_name参数默认为false。完全设置该参数将导致弃用警告。默认映射类型已删除。

我的建议是从映射中删除_doc类型。

更新

在弹性7.2.0上测试

我尝试创建以下映射：

PUT my_index
{
  "mappings": {
    "_doc": {
      "properties": {
        "category": {
          "type": "nested","properties": {
            "all_parents": {
              "type": "keyword"
            },"direct_parent": {
              "type": "keyword"
            },"paths": {
              "type": "keyword"
            }
          }
        },"slug": {
          "type": "keyword"
        },"parent_id": {
          "type": "integer","index": false
        },"images": {
          "type": "nested","properties": {
            "indie_url": {
              "type": "text","index": false
            }
          }
        },"tenant": {
          "type": "keyword"
        },"suggest_keywords": {
          "type": "completion","contexts": [
            {
              "name": "tenant","type": "category"
            }
          ]
        },"name": {
          "type": "text"
        },"description": {
          "type": "text","updated_at": {
          "type": "date"
        },"string_facet": {
          "type": "nested","properties": {
            "id": {
              "type": "keyword"
            },"value": {
              "type": "keyword"
            }
          }
        },"number_facet": {
          "type": "nested","value": {
              "type": "double"
            }
          }
        }
      }
    }
  }
}

和预期的一样，我收到此错误：

{
"error": {
    "root_cause": [
      {
        "type": "illegal_argument_exception","reason": "The mapping definition cannot be nested under a type [_doc] unless include_type_name is set to true."
      }
    ],"type": "illegal_argument_exception","reason": "The mapping definition cannot be nested under a type [_doc] unless include_type_name is set to true."
  },"status": 400
}

当我从映射中删除_doc时：

PUT my_index
{
  "mappings": {
      "properties": {
        "category": {
          "type": "nested","value": {
              "type": "double"
            }
          }
        }
      }
    }
}

我明白了

{

"acknowledged" : true,"shards_acknowledged" : true,"index" : "my_index"
}
