Explain sharding in mongodb?
Answer / Renu Paras
Sharding is a method of horizontally partitioning data across multiple MongoDB instances (called shards) to improve scalability and performance. Each shard contains a subset of the collection's data, and a routing service called the config server determines which shard should handle each query based on the shard key. Sharding allows you to store more data and distribute the load among multiple servers.
