摘要

The document provides a comprehensive guide to Apache ShardingSphere 5.1.1, detailing its features such as data scaling, encryption, sharding, and pluggable architecture. It outlines the processes for inventory, incremental, and switching phases in data scaling, using JDBC for data migration. Encryption is handled through SQL parsing and rewriting, supporting both plaintext and ciphertext storage. The management section covers metadata storage and dynamic orchestration of databases. Sharding functionality includes SQL processing steps and federation executor engine processes. The pluggable architecture is composed of three layers, enabling customization and extension of features without modifying kernel codes. The document also provides configuration details for ShardingSphere-JDBC, including Maven dependencies and data source creation, and explains resource operations, distributed databases, and DB discovery rules.
