Cascade Generated N+1 Query Problem

Database performance degraded after Cascade refactored data access code. Logs show hundreds of individual SELECT queries being executed instead of efficient batch loading. A single parent query triggers N queries for children.

Cascade likely generated loops that fetch entities individually instead of using batch loading or join strategies.

Error Messages You Might See

Slow database query detected Query timeout: SELECT took 30000ms Duplicate entities in result set from join
Slow database query detectedQuery timeout: SELECT took 30000msDuplicate entities in result set from join

Common Causes

  1. Cascade generated code that loops over results and calls repository methods inside loop
  2. Lazy-loaded collections accessed without join fetch in initial query
  3. Service methods iterate children without prefetching relationships
  4. Cascade removed .fetch(FetchType.JOIN) from existing JPQL queries

How to Fix It

Use JOIN FETCH in JPQL queries to eagerly load relationships. Replace loops with batch operations. Use @Query with explicit join strategies. Enable SQL logging to visualize query patterns. Consider pagination to limit data size.

Frequently Asked Questions

How do I detect N+1 queries?

Enable hibernate.generate_statistics and log SessionStatistics to count queries. Or use query profiling tools.

Should I use eager loading everywhere?

No, be selective. Use eager loading for data accessed in transaction, lazy for optional relationships.
