Start training with MongoDB Sharding is a method for distributing data across multiple machines. printShardingStatus ()` method on a `mongos` instance. Choose a shard key that optimizes data distribution and query efficiency in a sharded cluster, considering cardinality, frequency, and monotonicity. The output displays both the individual shard distribution information as well the total shard distribution: db. printShardingStatus() to see this information. MongoDB uses sharding to support deployments with very large data sets Official MongoDB Documentation.
