1. The Anatomy of the N+1 Query Problem
Batching and inserts/updates
- Debunk myths about Java persistence performance.
- Provide actionable advice for optimizing Java persistence.
2. Auto-Increment vs. Sequences
Did you know how the ID generation strategy affects batching? If you use IDENTITY (MySQL Auto-Increment), Hibernate disables JDBC batch inserts immediately because it needs the DB to generate the ID. ✅ The Fix: Use SEQUENCE identifiers (PostgreSQL, Oracle) to allow Hibernate to batch your inserts, reducing network chatter significantly.
