JPA makes database interaction feel almost magical—until your app grinds to a halt. In this talk, we’ll take a tour through the common (and not-so-common) performance pitfalls that turn object-relational mapping into an object-relational mess. From data loading surprises to connection mismanagement, we’ll explore real-world issues using a sample app: the FunFactStore, where fun facts are sold, but bugs are free.
We’ll dig into how seemingly harmless libraries can sometimes do more harm than good, and how tooling can help you spot trouble before your users do. Whether you’re using Spring Data JPA, navigating tricky transaction boundaries, or just wondering why things suddenly got slow, this session offers practical insights—and maybe a few fun facts.
