Database sharding is a technique used to split a large database into smaller parts called shards and store them across multiple servers. Each shard contains a portion of the data, which helps improve performance and manage large data efficiently. It is a form of horizontal scaling, where data is divided by rows and distributed to different databases. This reduces the load on a single server and allows faster data processing. Sharding offers benefits like: Better scalability Faster read/write performance Increased storage capacity High availability (system still works even if one shard fails) Different techniques like key-based (hash), range-based, and other architectures are used to distribute data across shards. However, it also brings challenges like increased complexity and data management issues. In simple words: Database sharding helps manage large data by dividing it into smaller parts and distributing it across multiple servers for better performance.
