Overview

Aeron Cluster provides an implementation of Raft Consensus upon which highly available services can be built.

Aeron Cluster has the following capabilities:

  • sequences multiple client connections into a single, replicated log
  • provides efficient fault tolerance with 2 or more nodes
  • provides Aeron Archive endpoints for writing to snapshots and reading from snapshots on start
  • allows 1 or more clustered services to be run, with support for inter-service sequenced messaging
  • reliable, sequenced timers
  • very high levels of performance, in particular with premium features such as Solarflare EF_VI kernel bypass

Typical use cases include:

  • host one or more central limit order books
  • host RFQ, IOI or similar negotiation logic
  • message sequencer
  • game state for multi-player games
  • any other scenario where you require fault tolerant, high performance state
