Achieve scalability and high availability without compromising on performanceAbout This BookSee how to get 100 percent uptime with your Cassandra applications using this easy-follow guideLearn how to avoid common and not-so-common mistakes while working with Cassandra using this highly practical guideGet familiar with the intricacies of working with Cassandra for high availability in your work environment with this go-to-guideWho This Book Is ForIf you are a developer or DevOps engineer who has basic familiarity with Cassandra and you want to become an expert at creating highly available, fault tolerant systems using Cassandra, this book is for you.What You Will LearnUnderstand how the core architecture of Cassandra enables highly available applicationsUse replication and tunable consistency levels to balance consistency, availability, and performanceSet up multiple data centers to enable failover, load balancing, and geographic distributionAdd capacity to your cluster with zero downtimeTake advantage of high availability features in the native driverCreate data models that scale well and maximize availabilityUnderstand common anti-patterns so you can avoid themKeep your system working well even during failure scenariosIn DetailApache Cassandra is a massively scalable, peer-to-peer database designed for 100 percent uptime, with deployments in the tens of thousands of nodes, all supporting petabytes of data. This book offers a practical insight into building highly available, real-world applications using Apache Cassandra.The book starts with the fundamentals, helping you to understand how Apache Cassandra's architecture allows it to achieve 100 percent uptime when other systems struggle to do so. You'll get an excellent understanding of data distribution, replication, and Cassandra's highly tunable consistency model. Then we take an in-depth look at Cassandra's robust support for multiple data centers, and you'll see how to scale out a cluster. Next, the book explores the domain of application design, with chapters discussing the native driver and data modeling. Lastly, you'll find out how to steer clear of common anti-patterns and take advantage of Cassandra's ability to fail gracefully.Style and approachThis practical guide will get you implementing Cassandra right from the design to creating highly available systems. Through a systematic, step-by-step approach, you will learn different aspects of building highly available Cassandra applications and all this with the help of easy-to-follow examples, tips, and tricks.
