Answer 1

There are many things, but the most important ones are as follows:
* Document level write lock (currently database level). This will greatly improve the concurrency of mongo.
* Replaceable storage engine - users can choose to support compression, encryption or other types of storage engines according to different needs
*MMS automation - Automatically deploy, upgrade, and manage Mongo clusters
