Mongodb sharding – set shard size

mongodbmongodb-3.4sharding

I am very new to MongoDB and am trying to do database sharding.

I have created two MongoDB shards and inserted 10000 records in it. I have used shard key as "no" which increments by 1 in every document in ascending order.

mongos>sh.addShard("localhost:27004",{"no":1})


Here, when I insert the records, the shard 1 gets only 6 records and shard 2 gets the rest of the records.

The output of sh.shatus() is:

 databases:
{  "_id" : "shard_test_2",  "primary" : "shard0000",  "partitioned" : true }
shard_test_2.test
shard key: { "no" : 1 }
unique: false
balancing: true
chunks:
shard0000       2
shard0001       1
{ "no" : { "$minKey" : 1 } } -->> { "no" : 1 } on : shard0000 Timestamp(2, 1) { "no" : 1 } -->> { "no" : 6 } on : shard0000 Timestamp(1, 2) { "no" : 6 } -->> { "no" : { "$maxKey" : 1 } } on : shard0001 Timestamp(2, 0)


Now, I want my shard one to store more documents than 6.

I read that how many documents will go to which shard is the function of balancer. So, how do I configure the balancer?

Or is there any other way of setting how much data should go to which shard?
No resource online is helping much in this.
