MongoDB Sharding

Sharding in MongoDB is the process of horizontally splitting data across multiple servers/nodes to handle large datasets efficiently.

In MongoDB, partitioning is a general technique of dividing data into smaller chunks (parts) for manageability, while sharding is a specific form of partitioning that distributes those chunks (shards) across multiple servers to achieve horizontal scaling and high availability.

To shard a database means to split its data horizontally into smaller chunks (shards) and distribute those shards across multiple servers or nodes.

To shard an existing database, you can split data into smaller chunks, known as shards, using a proper shard key and distribute the shards across multiple servers to achieve horizontal scaling.
