This book shows how to build a database backend capable of serving over a million operations per second with millisecond latency, while operating with hundreds of terabytes of data. The book helps you to master the proper design to successfully deploy ScyllaDB’s shard-per-core architecture and self-tuning features, to scale your applications upward, outward, and even across multiple data centers or continents, all while maintaining operational simplicity and the peace of mind that goes with it. The book begins by showing how to install ScyllaDB on your developer workstation. Using that install as a base, the book takes you through the concepts that underlie ScyllaDB and the application design patterns that lead to successful implementations and scalable applications. You’ll learn about typical application design pitfalls and problems, and potential ways to avoid them. You’ll come away with the knowledge to create production database clusters and high-performance, distributed applications that scale to reach their peak performance while maintaining high availability.  What You Will Learn Concepts that the ScyllaDB is built around Application design and data modeling best practices Database structures and database internal operations  Capacity planning and performance testing techniques ScyllaDB’s high availability and the data consistency model How to install ScyllaDB, from a workstation through a petabyte clusters How to operate, monitor, and troubleshoot a ScyllaDB system Hands on operations with the cqlsh and nodetool CLIs  Who This Book Is For
