Puzzling out Java's Project Jigsaw

Theresa Mammarella (IBM)

While modularity isn't exactly new (ehem... OSGi), the introduction of Jigsaw (JPMS) in Java 9 moved the concept to the front of developers minds. But while migrating to Java 9+ brings some challenges, it's not actually necessary to write modules. So why care about modularity if the classpath is still good enough? Can modularity bring any practical value to your applications? In this session I'll discuss why you should consider leveraging JPMS in designing new Java applications and highlight some practical knowledge and resources to get you started.

Jakarta NoSQL: One API to many NoSQL databases into Cloud Native age

Otavio Santana (Self-employed)

The next generation Database Management Systems do their best to be non-relational, distributed, open-source, and horizontally scalable.
These banks are very easy and make any software engineer's job more comfortable, but the number of NoSQL databases are enormous! There are currently about three hundred non-relational databases, and that number keeps growing. The first question is: how to deal with so many databases? After all, there are several issues with this; there’s a learning curve for each new API, not to mention the vendor-lockin impact.

Demystifying Garbage Collection in Java

Igor Braga (IBM)

This talk is meant to demystify how garbage collection (GC) works in a Java runtime. The beginning of the talk will be focused on what GC is, discuss truths and myths, and how it is useful for the lifetime of a program. After laying out the basics I’ll explain how each GC algorithm work and how they can be implemented in a real world JVM (e.g. OpenJ9, Hotspot). How are these algorithms put together to make up a good GC configuration, and how one can better select a configuration/policy for their application? These are some of the questions that I will be addressing during this talk.
