jpa-hibernate-optimization

## What problem does it solve? JPA/Hibernate based applications often suffer from inefficient entity design and N+1 queries, leading to slow data access and scalability challenges.

## Core Features & Use Cases

• Entity design optimizations including indexing, lazy loading, and proper association mappings
• Query optimization using JOIN FETCH, DTO projections, and pagination
• Caching strategies including second-level cache configuration to reduce repeated database access
• Use case: optimize a politician listing page to load related party and district data with minimal queries

### Quick Start Use the jpa-hibernate-optimization skill to apply a JOIN FETCH on related entities and enable second-level caching for the Politician entity.
