I love these SQL layers but they can obfuscate how they implement their transforms. So, they can speed up filter and join creation and coding... til something breaks and then you have to go atomic anyway.
Each of the runtimes, supported by Fugue, can be compared to Ray, but Fugue is a tool of a different kind.
Fugue SQL is one way, and it also has functional API. They both can be translated into the underlying runtime. You can choose based your preference and real need.
