Why Open Session in View (OSIV) Can Kill Your Spring Boot Performance

Spring Boot’s default Open Session in View (OSIV) keeps Hibernate sessions open throughout the request, silently triggering lazy‑loaded queries during JSON serialization, leading to N+1 problems and massive DB load under load, but disabling it and using explicit fetch joins restores performance.
