Hear what readers are saying about Database Performance at Scale

Damn, this is an excellent resource. Lots of interesting stuff + frank discussion of how to truly evaluate different database options.”
- Alex Debrie
A worthy companion to the Database Internals book!”
- Pekka Enberg
The book introduces you to the world of highly scalable databases with all the caveats of measuring, planning, and designing their usage and deployments. And it does so in a really good way, sprinkling nice humor here and there and showing how a well-managed scalable DB will behave if you treat it right.”
