Does this skill support CQRS patterns?

Yes, it includes specific templates for separating read and write concerns, including the use of specialized query services and JdbcTemplate for high-performance read-only operations.

How does this skill handle N+1 query problems?

It provides specific patterns and implementation guides for using JOIN FETCH and DTO projections to ensure associations are loaded efficiently in a single database round-trip.

Why should I only create repositories for aggregate roots?

Restricting repositories to aggregate roots ensures clear domain boundaries and prevents tightly coupled data access that can lead to complex maintenance issues and broken encapsulation.

Can I use this for complex dynamic filtering?

Absolutely. The skill includes standardized patterns for Custom Repositories using the Criteria API and EntityManager to handle complex, dynamic search requirements.

Implements high-performance Spring Data JPA repositories and entities using modern aggregate-centric patterns.

This skill provides a comprehensive framework for building robust data access layers in Spring Boot applications. It enforces industry-standard patterns such as restricting repositories to aggregate roots, utilizing DTO projections for read-heavy operations, and implementing CQRS patterns for complex queries. By providing templates for custom repositories, performance optimization checklists, and advanced relationship mapping, it ensures developers avoid common pitfalls like N+1 query issues and LazyInitializationExceptions while maintaining clean, testable, and production-grade persistence code.
