Question

我继承了一个遗留代码，该代码使用Elastic Search API创建索引和索引内容。

映射JSON是为v1.5创建的，其外观如下：

{
  "settings": {
    "index": {
      "number_of_shards": 1,
      "number_of_replicas": 0
    },
    "mappings": {
      "users": {
        "properties": {
          "created_at": {
            "type": "date",
            "format": "yyyy-MM-dd HH:mm:ss"
          },
          "id": {
            "type": "double"
          },
          "name": {
            "type": "string"
          },
          "org_id": {
            "type": "double"
          },
          "type_priority": {
            "type": "double"
          }
        }
      },
      "comment_idea": {
        "properties": {
          "author_id": {
            "type": "double"
          },
          "comment": {
            "type": "string"
          },
          "created_at": {
            "type": "date",
            "format": "yyyy-MM-dd HH:mm:ss"
          },
          "id": {
            "type": "double"
          },
          "idea_id": {
            "type": "double"
          },
          "org_id": {
            "type": "double"
          }
        }
      },
  }
}

当然，还有更多类型，例如 users ， comment_idea ，如上例所示。

由于我对Elastic Search不太熟悉，我的问题是如何为7.1转换此映射JSON？

据我所知7.1删除了 types ，并且此映射JSON被认为是无效的-我没有收到错误，但不接受（创建）该映射。

由于您不能在一个索引中存储多个映射类型，因此您需要将该多类型索引拆分为多个索引。另外，您需要将string更改为text。

因此，您需要创建多个索引，如下所示：

PUT users
{
  "settings": {
    "index": {
      "number_of_shards": 1,
      "number_of_replicas": 0
    }
  },
  "mappings": {
    "properties": {
      "created_at": {
        "type": "date",
        "format": "yyyy-MM-dd HH:mm:ss"
      },
      "id": {
        "type": "double"
      },
      "name": {
        "type": "text"
      },
      "org_id": {
        "type": "double"
      },
      "type_priority": {
        "type": "double"
      }
    }
  }
}

PUT comment_idea
{
  "settings": {
    "index": {
      "number_of_shards": 1,
      "number_of_replicas": 0
    }
  },
  "mappings": {
    "properties": {
      "author_id": {
        "type": "double"
      },
      "comment": {
        "type": "text"
      },
      "created_at": {
        "type": "date",
        "format": "yyyy-MM-dd HH:mm:ss"
      },
      "id": {
        "type": "double"
      },
      "idea_id": {
        "type": "double"
      },
      "org_id": {
        "type": "double"
      }
    }
  }
}

将映射架构从1.5迁移到7.1
