Vlad Mihalcea is a Java Champion, creator of Hypersistence Optimizer and the Hypersistence Utils Open-Source project.
He is passionate about Java, system architecture, and database systems.
He has written hundreds of articles about Java, JPA, Hibernate, and SQL on his blog, and he is the author of the High-Performance Java Persistence book and video course series.
In this talk, I'll take the worst possible Spring Boot application, riddled with tons of performance issues, and optimize it live.
This is a hands-on session, and I'll use various tools, such as VisualVM, IntelliJ IDEA Profiling, Hypersistence Optimizer, and PostgreSQL Auto_Explain, to demonstrate how you can transform a Spring Boot application that barely crawls into one that runs like a cheetah.
So, if you are a Java developer who writes web and enterprise applications that persist data into a relational database system, then you will surely find this talk useful because the problems I'm showing you are very common, so there's a good chance that you'd bump into these issues as well.
