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.

Database gateway

In this section, we will go through real real-world examples featuring database gateway. We will first start by reviewing the deployment architecture, followed by the configuration and testing for both of ShardingSphere's clients – Proxy and JDBC.

The deployment architecture

In this case, the underlying database adopts PostgreSQL, deployed with the read/write splitting architecture of one host and two secondaries. The upper database layer adopts a hybrid deployment solution of ShardingSphere-Proxy and ShardingSphere-JDBC. Based on the distributed governing capabilities provided by Cluster mode, you can easily modify cluster metadata online and synchronize the data to proxy and JDBC. Proxy can use the ShardingSphere built-in DistSQL to achieve traffic control operations (including circuit breaker) and disable the secondary database.

Figure 12.18 illustrates the typical deployment architecture, including both proxy and JDBC, and primary and...
