In database systems, what is sharding?

  • A feature for generating random data in a database
  • A method for encrypting data stored in a database
  • A process for optimizing database queries
  • A technique for breaking down a database into smaller, more manageable parts
Sharding is a technique used in database systems to horizontally partition data across multiple servers. It involves breaking down a database into smaller, more manageable parts called shards, which are then distributed across different servers. This helps improve scalability, performance, and availability by distributing the workload and reducing the burden on individual servers.
