The SMA information eXchange (SMA-X) is a high performance and versatile data sharing platform for distributed software systems. It is built around a central Redis database, and provides atomic access to structured data, including specific branches and/or leaf nodes, with associated metadadata. The lead architect of SMA-X is Attila Kovács at the Center for Astrophysics | Harvard & Smithsonian.
The smax-clib C/C++ client library was created, and is maintained, by Attila Kovács at the Center for Astrophysics | Harvard & Smithsonian, and it is available through the Smithsonian/redisx repository on GitHub.
