🚨 95% of Java developers use Spring Data JPA, Very few actually understand what happens after this line: "userRepository.save(user);" It’s NOT just: ➡️ Repository → Database The actual flow is: 🌐 HTTP Request → Controller → Service (@Transactional) → Repository → EntityManager → Persistence Context (1st Level Cache) → Hibernate → JDBC Driver → Database If you don’t understand these concepts, you’re likely writing code without knowing what’s happening behind the scenes: ✅ Persistence Context ✅ Entity Lifecycle ✅ Dirty Checking ✅ Flush ✅ Lazy vs Eager Loading ✅ JPQL vs Native SQL ✅ Locking ✅ N+1 Query Problem These are the concepts that separate developers who use JPA from those who can debug, optimize, and build scalable backend systems. I created this visual to simplify everything into a single roadmap. 📌 Bookmark it—you’ll thank yourself before your next Java interview. 💬 Which JPA concept confused you the most when you were learning? #Java #SpringBoot #JPA #Hibernate #Backend #SoftwareEngineering #Programming #Coding #Developer #Tech

@CodeWithAmann Services like Redis always maintain data consistency by regularly storing it to persistent storage(permanent DB)

I never expected this to happen. ❤️ Yesterday, I celebrated 50 followers. Less than 20 hours later, I crossed 100 verified (Premium) followers. 🚀 Thank you to everyone who’s here. If even one of my posts helped you learn something new or look at a problem differently, then I’m doing something right. Here’s to learning, building, and growing together. 💙
