Talks on Wurreka:

A Policy Engine is a tool that allows for checking user privileges as well as evaluate a responsibility matrix based on dynamic data for a given user. A Policy Engine is not only an Entitlement Management System but also provides for functional evaluation of conditions that result in deterministic responsibilities for a given user or actor.

This session shows how to utilize Open Policy Agent with Spring Boot and HOCON to produce a responsibility management solution that scales to volume and performance needs.

Some hiccups that were faced while deriving the most optimal solution are also highlighted. A short explanation of some tooling built for validating the policy files in the IDE will also be discussed.

Modern Java has a collection of sophisticated Garbage Collection patterns and models.

This session will provide an overview of how basic Garbage Collection patterns and models work in Java. The presentation material includes various Regional Collector JVM options and flags for tuning GC behavior as well as new logging techniques using Java Unified Logging.

Details will be shared about the new garbage collectors being introduced since Java 10, covering Shenandoah, ZGC and Epsilon.
