How to rebalance mongodb after adding shard

Question

How to rebalance mongodb data after adding a new shard

I don’t think he does it automatically?

I could not find anything, is there support?

Also the key for my shards is unique

Thank,

When you add a new shard, MongoDB should automatically begin rebalancing the data according to your shard key.

However, it will not begin balancing until a certain amount of data has been determined. Therefore, if you have little data, you probably will not see rebalancing.
