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.

Apache ShardingSphere and Database Mesh

Although Database Mesh and Apache ShardingSphere may sound similar in some aspects, they are not the same. For example, in contrast to Database Mesh, ShardingSphere's Smart SQL LB doesn't intrude into compute or storage nodes, ultimately making it truly adaptable to any kind of database.

However, a combination of Database Mesh and Apache ShardingSphere can improve interaction performance through a private protocol.

Smart SQL LB can generate an abstract syntax tree (AST) via the SQL parser. So, in the future, starting from version 5.1.0, Apache ShardingSphere will open a private protocol: when it receives SQL requests, it can also receive an AST concurrently to improve its performance in the appropriate manner. For example, apart from SQL parsing, in some scenarios such as single-shard routing, it's feasible to identify SQL features and directly access backend database storage nodes without Apache ShardingSphere.
