Master Hibernate and JPA with Spring Boot in 100 Steps - Step 85 - Performance Tuning - Eager Versus Lazy Fetch

The video tutorial discusses the performance implications of eager versus lazy fetch strategies in Hibernate. It explains that the choice between eager and lazy fetch depends on specific use cases, such as whether entity details are needed every time. The tutorial also covers how to configure these strategies, noting that many-to-one and one-to-one mappings are eager by default, while others are lazy. The video concludes with a brief introduction to the N + 1 problem, which will be explored further in the next video.
