CHAPTER 12

Sharding

Whether you’re building the next Facebook or just a simple database application, you will probably need to scale your app up at some point if it’s successful. If you don’t want to be continually replacing your hardware (or you begin approaching the limits of what you can do on just one piece of hardware), then you will want to use a technique that allows you to add capacity incrementally to your system, as you need it. Sharding is a technique that allows you to spread your data across multiple machines, yet does so in a way that mimics an app hitting a single database.

Ideally suited for cloud-based computing platforms, sharding ...
