How does this skill help prevent N+1 query issues?

It provides patterns for using JOIN FETCH in JPQL and DTO projections to ensure that related entities are fetched efficiently in a single database round-trip.

Does it include configuration for connection pooling?

Yes, it provides recommended production-ready properties for HikariCP, including pool size, timeout settings, and PostgreSQL-specific LOB handling.

Can this skill help with database migrations?

Yes, it recommends and provides patterns for using Flyway or Liquibase to manage versioned, idempotent database migrations instead of relying on Hibernate auto-DDL.

Is this skill limited to Spring Boot applications?

While the implementation examples focus on Spring Boot and Spring Data JPA, the core JPA and Hibernate patterns are applicable to any Java-based persistence layer.
