I'm curious if a non-source-generated solution would work, specifically Scala Native and Graal? That is, there are non-JVM targets that can be built from the Scala source, and they can be extremely performant. The current hotness is the "billion row challenge" ( https://github.com/gunnarmorling/1brc) where Graal-based solutions are hands-down the winners.
