node.js - nodejs和php，python从mongodb数据查找数据那个快（3200万条记录）
有一个mongodb数据库,里面把一张表分割成了16个collection，每个collection有200万----300万条记录
现在每天需要根据特定的条件查询count数
只从单纯的编程语言来说，应该那种更快，不考虑并发之类的问题

显然瓶颈在 MongoDB, 和你用啥语言没有关系。
现在每天需要根据特定的条件查询count数
你是要统计所有的collection count还是单独的？
其实我建议你如果count时间太长，你应该单独有个字段在insert时去+1，count去看那个字段就好了
至于你提到的编程语言，和ls说的一样，没多大的关系，瓶颈在db
有数据库连接池的快……
