Track: Taking Java to the Next Level


Day of week:

Java is so much more than a language. It is a mature platform with a dynamic ecosystem of libraries, toolkits, and language that power the modern enterprise. In Taking Java to the Next Level, our track host Monica Beckwith (JVM Performance Consultant, Java Rockstar, and ex-performance lead for the Garbage First Garbage Collector) has put together a compelling story of Java the Platform. In the track, you will learn lessons from OpenJDK optimizations at Twitter, explore why Java powers core services at Apple, and learn real-world tips from experts on tuning Java for the real world. Taking Java to the Next Level track is a rockstar lineup that pushes you to new heights in how you optimize, tune, and work with and old friend: Java.

Track Host:
Monica Beckwith
Led the performance effort for Java's G1 Garbage Collector
Monica Beckwith is an Independent Consultant specializing in optimizing the Java Virtual Machine and the Garbage Collectors for enterprise applications. She is a regular speaker at various conferences and has several published articles on topics including garbage collection, the Java memory model and others. Monica led Oracle's Garbage First Garbage Collector performance team, and was named a JavaOne 2013 Rock Star.

JVM Performance Lead Engineer @Oracle

Many folks are familiar with the three performance attributes of throughput, latency and (memory) footprint. And, many further understand the relationship with each. For instance, an improvement in one comes at the sacrifice of one or both of the other two, or an improvement in two comes at the sacrifice of the remaining one. However, there are times where improvements can be realized in all three. But, it usually requires a lot non-trivial development work.

HotSpot JVM Performance Optimization @Twitter

Twitter runs a swarm of services executing on several different managed runtimes. The services have migrated from mainly Ruby in the past to mostly Scala today. Targeting the JVM allows developers to quickly write and deploy reliable code. Automated memory management, in particular, improves productivity of teams in a fast paced environment. But with these benefits also come challenges. The way code is executed on the JVM makes trouble-shooting quite tricky, especially in production, as it...

Netty Core Developer & Cloud Infrastructure Engineering @Apple

Learn how Apple uses Netty for its Java based Services and the challenges of doing so, including how we enhanced performance by participating in the Netty OpenSource community. A deep dive into advanced topics like JNI, JVM internals, among others, will be included.

Generics are one of the most complex features of Java. They are often poorly understood and lead to confusing errors. Unfortunately, it won’t get easier. With the introduction of Value Types, proposed for Java 10 in 2018, Generics will be extended yet again. It’s now time to understand generics or risk being left behind.

We start by stepping back into the halcyon days of 2004 and explain why generics were introduced in the first place back. Then we travel to the present to explaining...

Co-founder and CEO at Takipi

In this session we'll dive under the hood into the low-level techniques used by today's top Performance Management tools (APMs) such as NewRelic, AppDynamics and more to capture dynamic performance metrics in real-time. We'll see how you can easily write your own JVM agent to capture accurate performance data for virtually any type of application from Java micro-services to reactive actor systems in Scala, and connect them to any modern DevOps graphing and alerting tool.
