Aeron

Efficient reliable UDP unicast, UDP multicast, and IPC message transport. Java, C, and C++ clients are available in this repository, and a .NET client is available from a 3rd party. All clients can exchange messages across machines, or on the same machine via IPC, very efficiently. Message streams can be recorded by the Archive module to persistent storage for later, or real-time, replay. Aeron Cluster provides support for fault-tolerant services as replicated state machines based on the Raft consensus algorithm.

Performance is the key focus. A design goal for Aeron is to be the highest throughput with the lowest and most predictable latency of any messaging system. Aeron integrates with Simple Binary Encoding (SBE) for the best possible message encoding and decoding performance. Many of the data structures used in the creation of Aeron have been factored out to the Agrona project.

For details of usage, protocol specification, FAQ, etc. please check out the Wiki.

For those who prefer to watch a video then try Aeron Messaging from StrangeLoop 2014. Things have advanced quite a bit with performance and features, but the basic design still applies.

For the latest version information and changes see the Change Log with Java downloads at Maven Central.

Commercial support, training, and development on Aeron is available from [email protected]. Premium features are available to customers on commercial support which include transport bindings for Solarflare/Xilinx ef_vi, Mellanox VMA, and AWS DPDK for further reduction in latency and increased throughput. Secure communications is available with ATS (Aeron Transport Security) for encrypted streams.
