In this video I will explain the basic rules you should follow to always pick the right projection for your use case. Choosing the right projection when selecting data with JPA and Hibernate is incredibly important. When I’m working with a coaching client to improve the performance of their application, we always work on slow queries. At least 80% of them can be tremendously improved by either adjusting the projection or by using the correct FetchType. Unfortunately, changing the projection of an existing query always requires a lot of refactoring in your business code.
