 Description   

Such as the title, I deploy a Sharded Cluster, in order to reduce the write pressure, so I use hash based sharding. But it will insert records randomly, is there anyways to decide it by myself?

Perhaps, if I can devide all sharding(e.g. : 10 shards) into two groups(group A <4 shards>, group B<6 shards>), A just insert users information, B just insert other information.

dnviyth, you may want to read about tag aware sharding for your use case.

Please note that the SERVER project is for reporting bugs or feature suggestions for the MongoDB server. For MongoDB-related support discussion please post on the mongodb-user group or Stack Overflow with the mongodb tag, where your question will reach a larger audience. A question like this involving more discussion would be best posted on the mongodb-user group. See also our Technical Support page for additional support resources.

Regards,
Ramón.
