Achieve scalability and high availability without compromising on performance About This Book • See how to get 100 percent uptime with your Cassandra applications using this easy-follow guide • Learn how to avoid common and not-so-common mistakes while working with Cassandra using this highly practical guide • Get familiar with the intricacies of working with Cassandra for high availability in your work environment with this go-to-guide Who This Book Is For If 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 Learn • Understand how the core architecture of Cassandra enables highly available applications • Use replication and tunable consistency levels to balance consistency availability and performance • Set up multiple data centers to enable failover load balancing and geographic distribution • Add capacity to your cluster with zero downtime • Take advantage of high availability features in the native driver • Create data models that scale well and maximize availability • Understand common anti-patterns so you can avoid them • Keep your system working well even during failure scenarios In Detail Apache 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 Cassandras architecture allows it to achieve 100 percent uptime when other systems struggle to do so. Youll get an excellent understanding of data distribution replication and Cassandras highly tunable consistency model. Then we take an in-depth look at Cassandras robust support for multiple data centers and youll 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 youll find out how to steer clear of common anti-patterns and take advantage of Cassandras ability to fail gracefully. Style and approach This 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.
