High Performance Managed Languages
YET TO BE SCHEDULED
Topics:
Performance
Compilers
Garbage Collection
Memory Management
Level:
Intermediate

Common wisdom dictates that native languages are the only means of building high-performance applications. How do managed runtimes such as those available to .NET, Java, and even JavaScript, yes even JavaScript compare? Many applications requiring high-performance are now developed for managed runtimes - such as financial trading, data stores and analytics, messaging processing, and even supercomputing.

Over the last few decades we have seen significant advances in managed runtimes, particularly for JIT compilers and garbage collectors. In this talk we will explore how our managed runtimes can equal, and even better in some cases, the performance of native languages.

Workshop

High-Performance Messaging with Aeron
Wednesday 9:00 - 17:00
Topics:
Concurrency
Messaging
Networking
Protocols
Microservices
Level:
Advanced

In this workshop you will learn how to build microservices with Aeron and SBE in Java. Microservices capable of handling millions of messages per second with very low and predictable response times. We will cover some networking theory and the design of Aeron so you know how to use it with mechanical sympathy.

Topics covered will include:

  • Network Fundamentals
  • Aeron Design
  • Encoding & decoding messages with SBE for zero copy semantics
  • Handling large messages and streaming
  • Monitoring, debugging, and spying on streams
  • Basic tuning for performance and resource management
  • "Multicasting" in the cloud with multi-channel-cast
  • Configuring message delivery service levels: allow loss, reliable, durable, etc.
  • Flow control and congestion control strategies
  • When and how to use them.
  • Customising channel endpoints for extending Aeron, e.g. testing loss scenarios.

Delegates need a laptop with Java 8 installed and be comfortable with hands on coding.

Workshop is aimed at intermediate to advanced but I do plan to start with the fundamentals and build up.

About

Martin is a Java Champion with over 2 decades of experience building complex and high-performance computing systems. He is most recently known for his work on Aeron and SBE. Previously at LMAX he was the co-founder and CTO when he created the Disruptor. Prior to LMAX Martin worked for Betfair, three different content companies wrestling with the world largest product catalogues, and was a lead on some of the most significant C++ and Java systems of the 1990s in the automotive and finance domains. He blogs at mechanical-sympathy.blogspot.com, and can be found giving training courses on performance and concurrency when he is not cutting code to make systems better.
