                                               Photo by Azamat Esenaliev Sharding and federation are both techniques for managing large datasets across multiple systems, but they differ in key aspects: Data Location: Sharding: Data is physically divided and distributed across different shards (databases or servers). Each shard holds a specific subset of the data, usually based on a key or range. Accessing data requires routing to the appropriate shard based on the key.
