数据结构如下
/* 6 */
{
"_id" : ObjectId("591e91ea0fde9f017a9d6e9d"),
"app" : "啦啦啦啦",
"date" : "2017-05-19",
"uid" : 10002,
"nickName" : "qwe",
"count" : 2,
"card" : 2
}
/* 7 */
{
"_id" : ObjectId("591ea6950fde9f017a9d7a13"),
"app" : "呵呵呵",
"date" : "2017-05-19",
"uid" : 10003,
"nickName" : "asd",
"count" : 2,
"card" : 2
}
数据量已超数十万
尝试建立索引并没有得到预想的结果,反而更慢
求方案,在线等
