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.

Plugin platform

Engineers may choose ShardingSphere-JDBC or ShardingSphere-Proxy, but when they use Apache ShardingSphere, they actually call the same kernel engine to process SQL. Though Apache ShardingSphere with its complex structure contains many features, its microkernel architecture is extremely clear and lightweight.

Microkernel ecosystem

The core process of using Apache ShardingSphere is very similar to that of using a database, but ShardingSphere contains more core plugins for users, together with extension points. An overview of the kernel architecture is shown in the following diagram:

Figure 2.8 – Kernel architecture overview

The preceding diagram shows the three layers of the architecture—namely, the innermost microkernel, the pluggable service provider interfaces (SPIs) in the middle, and the pluggable ecosystem placed at the outermost layer.

The microkernel processing workflow involves two standard modules, SQL Parser...
