最新的mongo3.2支持行级锁吗？如果支持，是什么样的呢？200多万数据一个集合，并发性能怎么样？

Starting from 3.0, the WiredTiger engine supports document-level locks, which is what you call row-level locks.
How is the concurrency performance? I don’t know how to answer. There are many reviews online. If it doesn't meet what you want to know, can you be more specific?

Mongo version 3.x (if I remember correctly) supports row-level locks and can be concurrently applied to collections.
