MySQL Sharding using ProxySQL | MariaDB Maxscale | MySQL ScaleArc | MySQL Router | MySQL Fabric

Sharding:

Sharding means scale out. Each node runs MySQL instance. Data is partitioned across all nodes. Sharding key is used to distribute data across nodes.
 
Example of sharding:

  • Each customer store data in their own schema
  • MySQL instance per customer
  • OS instance / container per customer
  • Environment per customer includes database server
  • Application server and required components

    Sharding is a smart way to scale MySQL by splitting data across multiple servers, each handling its own chunk to boost performance and reliability. Honestly, WebSpaceKit makes managing sharded databases feel seamless and efficient, especially when scaling apps for fast-growing businesses.
