Cluster Consensus: when Aeron met Raft
YET TO BE SCHEDULED
Topics:
Consensus Performance Messaging
Level:
General

Consensus protocols enable distributed systems to agree a common view of shared state. This common view allows a cluster to continue service while a majority of its members are available.  Raft was designed to be understandable. Raft succeeded in this goal and became popular.

Aeron was designed to be an understandable messaging system, it was also designed to be fast, very fast. If the design principles of Aeron were applied to Raft, could we create a high-performance consensus implementation? Come to this talk if you would like to find out what happened when Aeron met Raft.

Workshop

High-Performance Messaging with Aeron
Wednesday 9:00 - 17:00
Topics:
Messaging
Performance
Networking
Level:
Intermediate

In this workshop you will learn how to build microservices with Aeron (https://github.com/real-logic/aeron) and SBE (https://github.com/real-logic/simple-binary-encoding) 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, recorded, clustered, etc.
  • Flow control and congestion control strategies – When and how to use them.
  • Customising channel endpoints for extending Aeron, e.g. testing loss scenarios.
  • How to build a non-blocking microservice using a single thread.
Delegates need a laptop with Java 8 installed and be comfortable with hands on coding.

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.
