It's not every day that Mark Stoodley, IBM's Chief Architect for Java, flies from Canada to Europe to lead a hands-on workshop. At JCON EUROPE 2025, you have a rare opportunity to sit down, code, and ask your questions to one of the most influential technical leaders in the Java world.
With over two decades of deep JVM experience, Mark has shaped the runtime used by thousands of enterprise applications worldwide. He led the transformation of IBM's J9 JVM into the open-source OpenJ9 and OMR projects. This isn't just a workshop—it’s your chance to tap directly into the mind of the architect behind the tech that powers your Java workloads.
Workshop: Ultra Efficient Startup for Production Java Workloads
Struggling with slow Java startup times? Tired of burning CPU and memory just to get past warm-up? Mark will guide you through cutting-edge JVM performance optimizations.
What You’ll Learn (and Take Back to your projects):
-
Real-world strategies to cut your Java startup and warm-up time
-
How to reduce infrastructure cost and energy use without compromising speed
-
When to go native—and when JVM tech is the smarter choice

3 years agoI see that you save the point of interest as text in the DB but the response gotten from ChatGPT is JSON. Does this mean you convert the response into string using libraries like gson before saving it in the database?

3 years agoHey, The response is a String object in the JSON format [1]. The repository takes this JSON string as is and stores to the database [2]. Presently, Spring Data auto-generates the CREATE TABLE statement on the startup and sets the "point of interest" column's type to "text" (or "varchar", don't remember). However, it's always possible to ask Spring Data to use the "json" or "jsonb" type for the column if you wish to query the JSON at the database level. Finally, Vaadin displays a list of PointsOfInterests. Those are generated using the org.json library [3]. Let me know if you have other questions. Hope this helps.
