1.标签索引mapping

PUT userprofile_tags
{
  "mappings": {
    "_doc": {
      "properties": {
        "userid": {
          "type": "keyword"
        },
        "userlabels": {
          "type": "nested"
        },
        "data_date": {
          "type": "keyword"
        }
      },
      "dynamic_templates": [
        {
          "string_template": {
            "path_match": "userlabels.*",
            "mapping": {
              "type": "keyword"
            }
          }
        }
      ]
    }
  }
}

2.添加document

PUT userprofile_tags/_doc/1
{
    "userid" : "5",
    "userlabels" : {"tagCode1":"tagValue","tagCode2":"1"}
}

3.标签mysql元数据表

  `id` varchar(50) NOT NULL COMMENT 'id',
  `code` varchar(50) DEFAULT NULL COMMENT '标签code',

  PRIMARY KEY (`id`) USING BTREE
) ENGINE=InnoDB DEFAULT CHARSET=utf8 ROW_FORMAT=DYNAMIC COMMENT='用户画像-标签元数据表';

INSERT INTO `userprofile_tag_metadata` VALUES ('69e48e958e892ed6aad02326d8ce131c', 'A111H001_001', '男', 1, 1, NULL, '336bd40fa83b4792f1c84d6a3cd4421b', '04cc50f4b5b04fa35ba16d8ac4f29a24/336bd40fa83b4792f1c84d6a3cd4421b', '04cc50f4b5b04fa35ba16d8ac4f29a24', NULL, '2020-08-26 16:53:39', '2020-08-26 16:53:39', 1, NULL, NULL, 2, NULL);
