A Definitive Guide to Apache ShardingSphere

By: Trista Pan, Zhang Liang, Yacine Si Tayeb

Overview of this book

Apache ShardingSphere is a new open source ecosystem for distributed data infrastructures based on pluggability and cloud-native principles that helps enhance your database. This book begins with a quick overview of the main challenges faced by database management systems (DBMSs) in production environments, followed by a brief introduction to the software's kernel concept. After that, using real-world examples of distributed database solutions, elastic scaling, DistSQL, synthetic monitoring, database gateways, and SQL authority and user authentication, you’ll fully understand ShardingSphere's architectural components, how they’re configured and can be plugged into your existing infrastructure, and how to manage your data and applications. You’ll also explore ShardingSphere-JDBC and ShardingSphere-Proxy, the ecosystem’s clients, and how they can work either concurrently or independently to address your needs. You’ll then learn how to customize the plugin platform to define personalized user strategies and manage multiple configurations seamlessly. Finally, the book enables you to get up and running with functional and performance tests for all scenarios. By the end of this book, you’ll be able to build and deploy a customized version of ShardingSphere, addressing the key pain points encountered in your data management infrastructure.

An introduction to elastic scaling

For a fast-growing business, support systems are generally under pressure, and all the layers of the hardware and software systems may become bottlenecks. In serious cases, there may be problems such as high system load, response delay, or even inability to provide services, thus affecting the user experience and causing the enterprise to incur losses.

From a system perspective, this is a high availability issue. The general solution is simple and direct. The system's pressure issues that are caused by insufficient resources (for example, insufficient storage capacity) can be solved by increasing resources, while excess resources can be solved by reducing resources. This process belongs to capacity expansion and contraction – that is, elastic scaling.

There are two types of expansion and contraction schemes in the industry – vertical scaling and horizontal scaling:

  • Vertical scaling can be achieved by upgrading the...
