Welcome to Aeron Cookbook - introducing Aeron, Aeron Archive and Aeron Cluster to new and intermediate users through in depth guides and a cookbook.

Aeron offers efficient reliable UDP unicast, UDP multicast, and IPC message transport - with a core design goal of reaching the highest throughput with the lowest and most predictable latency of any messaging system. Aeron Archive allows message streams to be recorded to persistent storage for later, or real-time, replay. Aeron Cluster provides fault tolerant total ordering across multiple streams. Aeron is an open source project, hosted on GitHub.

Please note that this is not an official guide produced by Real-Logic. Related source code can be found on GitHub.
