VARIANT嵌套子列格式内容问题

目前再做es数据迁移doris, es的存储数据为
{
"9_4.5.4.1" : "个检报告",
"9_1.7.4.2" : "牙体",
"9_1.2.4.3" : "体重指数",
"9_1.7.4.5" : "舌",
"9_1.2.4.4" : "收缩压",
"9_1.7.4.4" : "牙周",
"9_1.2.4.1" : "身高",
"9_1.2.4.2" : "体重",
"9_4.4.4.1" : "营养早餐",
"9_1.2.4.5" : "舒张压",
"9_1.7.4.19" : "牙列"
}
迁移到doris数据解析成
{"9_1":{"2":{"4":{"1":"身高","2":"体重","3":"体重指数","4":"收缩压","5":"舒张压"}},"7":{"4":{"19":"牙列","2":"牙体","4":"牙周","5":"舌"}}},"9_4":{"4":{"4":{"1":"营养早餐"}},"5":{"4":{"1":"个检报告"}}}},
为了保证使用方无感迁移, 应该如何设置保证在doris存储内容与es结构一致
