Krakow, Poland, 17 - 19 June 2026
"In the blue corner: the undisputed heavyweight industry standard, the king of the ORMs, weighing in with a decade of dominance and millions of Stack Overflow answers... JPA!
In the red corner: the lean, type-safe challenger, the Sultan of SQL, the elite defender of the database... jOOQ!"
This session isn't just a talk; it’s a technical title fight. We’re going glove-to-glove on the issues that matter: the N+1 knockout, the "Criteria API" clinch, the power of code generation, and raw runtime performance. After every round, the referee (the audience) will vote to decide who landed the winning blow. Who will bring home the belt, and who will be left on the canvas? Your vote decides the champion.
