Features

1. Both dynamism and static

• Brings dynamism into static language ORM frameworks, achieving flexible capabilities for operating on complex dynamic data structures without compromising the complete compile-time safety checks of static languages, eliminating DTO explosion and unafraid of engineering expansion and changing requirements.
• Its innovative SQL DSL supports dynamic table joins and native SQL embedding, gracefully handling real-world complexity.

2. Powerful and easy cache

• Focuses on business and reaping caching gains. CDC solutions decoupled from specific caching technologies are transparent to business code.
• Automatic cache invalidation.
• Supports numerous application scenarios like object cache, association cache, calculation cache.
• Mature multi-view cache mechanisms easily integrate with permission requirements.

3. Convenient project support

Provides a one-stop solution for business system development.

• Supports client code generation.
• Simplifies REST and GraphQL service development.
• Supports cross-service data associations.

4. Ultimate performance

• Pursues meticulous optimizations, rejecting low-performance SQL generation.
• Powerful precompilation technology ensures efficient mapping from JDBC result sets to entity objects.

5. Low and controllable learning costs

Requires no special prior knowledge - veterans of any ORM can quickly and painlessly migrate. The learning curve is scientifically friendly, serving as a high-quality reference for new learners of ORM usage.

6. Rapid reuse of code assets

The combination of static and dynamic design realizes a higher level of abstraction from relational data to local graph structures. The high-performance one-stop solution isolates complex technical details, strongly supporting a focus on core business and rapid accumulation of highly reusable code assets.
