GaussDB(for MySQL) Service Overview 2 Product Architecture

2 Product Architecture

The overall architecture of GaussDB(for MySQL) consists of three layers from bottom to top.

1. Storage node layer: This layer uses DFV storage to provide distributed, strongconsistency, and high-performance storage capabilities to ensure data reliability and horizontal scalability.

2. Storage abstraction layer: This layer is key to ensuring database performance. It connects to the DFV storage pool downward and provides scheduled database storage semantics upward. Table le-based operations are abstracted into distributed storage.

3. SQL node layer: This layer reuses MySQL 8.0 code to be 100% compatible with open-source MySQL. You do not need to modify any code when migrating your services from MySQL or other databases to GaussDB(for MySQL). The MySQL-native syntax and tools are still available, reducing your development and learning costs. Apart from full compatibility, GaussDB(for MySQL) also optimizes the kernel, open-source hardening, open-source ecosystem, and commercial capabilities based on native MySQL.
