我有一个mongodb集合

{
"_id" : 57,
"value" : {
    "user" : [ 
     {
            "fk_status_id"  : "0",
            "firstname"     : "Ajith",
            "lastname"      : "S",
            "city"          : "known",
            "State"         :"kerala",          
            "location" : {
                "lat" : 34.123456,
                "lon" : -95.123456
            },
     }

    ],
}}

拥有数百万份文件

我想像这样改变表结构

{
"_id" : 58,
    "user" : [ 
     {
            "fk_status_id"  : "0",
            "firstname"     : "Ajith",
            "lastname"      : "S",
            "city"          : "known",
            "State"         :"kerala",          
            "location" : {
                "lat" : 34.123456,
                "lon" : -95.123456
            },
     }

    ]}

我的意思是,我想从这个结构中省略'value {}'.

• 数据应该超出'价值'.请解决我的问题.
