spring-jpa-performance

What problem does it solve?

Optimize JPA/Hibernate performance by preventing N+1 queries, reducing fetch overhead, and tuning caches and indexes to scale data access.

Core Features & Use Cases

• Prevent N+1 queries with fetch strategies (fetch joins, EntityGraph)
• Use projections (interfaces/DTOs) to minimize data transfer
• Efficient pagination (offset and keyset) for large datasets
• Bulk operations support and optimized batch updates/deletes
• Caching strategies and index design to improve lookup performance
• Real-world use cases: diagnosing slow queries in Spring data layers

Quick Start

Analyze existing JPA queries to identify bottlenecks and implement a fetch strategy that reduces unnecessary data retrieval.
