I believe technically there is Chronicles, Epics own "database framework/abstraction" that runs on top of Caché. Then about Caches superiority, this is the only public benchmark that I could find (from Intersystems) https://community.intersystems.com/sites/default/files/documentation/Cache_benchmark-1c69bf617b51d5a2dee145442deaa371.pdf https://community.intersystems.com/sites/default/files/docum... Where 8-core server (back in 2009 that is) could do about 2 million database reads per second.
