Who this book is for
This book is for anyone who is curious about Cassandra. A beginner can start from Chapter 1, Quick Start, and learn all the way up to advanced topics. If you have an intermediate-level of experience, that is, you have worked on a toy project or better with Cassandra, you can skip to Chapter 2, Cassandra Architecture. The motivation is written keeping in mind a user who has a month of experience with Cassandra. Chapter 1, Quick Start, is aimed especially at newbies.
A DevOps engineer is probably the best job title for those who need to read the book end to end. If you wear multiple hats during the day (very common in startups)—writing code, managing infrastructure, working on analytics, and evangelizing your product—you may find this book extremely useful.
