Aeron is an efficient, reliable message transport supporting UDP unicast, UDP multicast, and IPC, with Java, C, and C++ clients. It includes Aeron Archive for recording/replaying streams and Aeron Cluster for fault-tolerant replicated state machines using Raft consensus.
Use cases
- build low-latency messaging between services over UDP or shared memory
- record and replay message streams for backtesting or recovery
- implement fault-tolerant replicated state machines with Raft consensus
- exchange messages efficiently between processes on the same machine via IPC
- build high-throughput trading or exchange systems
- stream market data via UDP multicast
When to choose
- you need the lowest, most predictable latency messaging at high throughput
- you're building trading systems, exchanges, or other latency-sensitive infrastructure
- you need efficient same-machine IPC plus network transport in one API
- you need stream recording/replay or fault-tolerant clustering
When to avoid
- you need a general-purpose broker with rich routing, queues, and broad client-language support like Kafka or RabbitMQ
- your throughput needs are modest and simplicity matters more than latency
- you need messaging over TCP or the public internet rather than UDP/IPC
