Abstract

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.

Question: 

How you you describe the persona and level of the target audience?

Answer: 

Senior developers and architects who need highly resilient systems without compromising performance. Typically these developers will be from a finance, gaming, betting, or high-volume transactional system domains.

Question: 

What do you want “that” persona to walk away from your talk knowing that they might not have known 50 minutes before?

Answer: 

An understanding of how consensus algorithms operate and the techniques that can be applied to make them efficient. Building a system on top of consensus algorithms requires very efficient interfacing to the algorithm and means to comprehend and monitor operation. We'll cover the mechanics of how this can work.

Question: 

What trend in the next 12 months would you recommend an early adopter/early majority SWE to pay particular attention to?

Answer: 

With the event of CPU exploits like Meltdown and Spectre we are seeing more people take performance and efficiency as a first class concern, especially on cloud platforms. From this we'll likely see an increase in adoption of user-space network and storage access libraries. The challenge comes from how we design our software to best utilise these significant changes in infrastructure.
