--- Sharding Status ---
sharding version: {

fensme.users
shard key: { "_id" : 1, "uid" : 1 }
chunks:
shard0000 1
{ "_id" : { "$minKey" : 1 }, "uid" : { "$minKey" : 1 } } -->> { "_id" : { "$maxKey" : 1 }, "uid" : { "$maxKey" : 1 } } on : shard0000 { "t" : 1, "i" : 0 }
fensme数据库是支持shard的，主shard是shard0000，对应host是localhost:10001
