You are working on optimizing a Spring Data JPA application experiencing N+1 select issues. How would you identify and resolve these issues while maintaining data consistency?
- Disable lazy loading for relationships to minimize additional queries.
- Implement batch fetching strategies or use join fetch to fetch related entities eagerly.
- Tune the database server's caching mechanisms for improved performance.
- Utilize non-relational databases like MongoDB to avoid N+1 select problems altogether.
To address N+1 select issues in Spring Data JPA while maintaining data consistency, you should implement batch fetching strategies or use join fetch to eagerly fetch related entities. Disabling lazy loading can lead to data inconsistency and is not recommended. Tuning the database server's caching mechanisms can improve performance but doesn't directly address the N+1 issue. Using non-relational databases is a significant architectural change and may not be suitable for all scenarios.
