This part seems really helpful. I would recommend this part as the most important part among the 5 chapters. It's really great that it covers everything from various performance optimization know-how to architecture.

Develop APIs using Spring Boot and JPA. And learn how to optimize JPA's extreme performance.

Real-world! Spring Boot and JPA Utilization 2 - API Development and Performance Optimization

Yes, this is the most important part. Hahaha I think Mr. Yoon Sung would have gained more since he is someone who continues to think about domain design and architecture. Thank you^^
