Preface

Apache ShardingSphere is a new open source ecosystem for distributed data infrastructures based on pluggability and cloud-native principles.

This book begins with a quick overview of the main challenges faced by DBMSs today in production environments, followed by a brief introduction to the ShardingSphere software's kernel concept. Thereafter, through real-world examples, including distributed database solutions, elastic scaling, DistSQL, synthetic monitoring, SQL authorization and user authentication, and database gateway, you will gain a full understanding of ShardingSphere's architectural components and how they are configured and can be plugged into your existing infrastructure to manage your data and applications. Moving ahead, you will get well versed with ShardingSphere-JDBC and ShardingSphere-Proxy, the ecosystem's clients, and how they can work either concurrently or independently according to your needs. Then, you will learn how to customize the plugin platform to define your personalized user strategies and manage multiple configurations seamlessly. Lastly, you will get up and running with functional and performance tests for all scenarios.

By the end of this book, you will be able to build and deploy your own customized version of ShardingSphere, addressing the key pain points encountered in your data management infrastructure.
