Database sharding with MySQL fabric

Why do we shard? How does sharding work? What are the different ways I can shard my database? This white paper goes through some of the theory behind sharding. It also discusses three different tools which are designed to help users shard their MySQL databases. And last but not least, it shows you how to set up a sharded MySQL setup based on MySQL Fabric and ProxySQL.
