Sharding is a database partitioning technique that divides an extensive database into smaller, more manageable parts called shards.
Sharding aims to improve database performance and scalability by distributing data and processing power across multiple servers, rather than relying on a single server. This helps reduce the amount of data that needs to be stored on any server and reduces the load on any database connection, improving overall speed and responsiveness.
In addition, sharding helps to ensure that even in the event of a server failure, the remaining servers can continue to operate, providing a high level of reliability and availability. Sharding is a common technique used in large-scale web and mobile applications, as well as in online gaming, e-commerce, and other data-intensive applications.
