Servlet vs Reactive: Choosing the Right Stack

What’s the motivation for this talk?

Spring Framework 5 provides two web stacks. One is a classic, Servlet stack with blocking I/O that most Java enterprise applications use today. The other is a Reactive stack that's built on an event-loop, non-blocking execution model and can handle high concurrency with less hardware resources. The motivation for this talk is to...

Practical Change Data Streaming Use Cases With Apache Kafka & Debezium

Performance Beyond Throughput:An OpenJ9 Case Study

What is the focus of your work today?

For the past 14 years I've been working on Java JIT compiler development at IBM. However, I am not your typical compiler guy because I don't focus that much on code generator or optimizer. Instead I deal with heuristics that determine what methods to compile, when to compile them and how much to optimize them. With Java, and any other...
