> Normalized keys are used to improve sorting performance by avoiding random memory accesses.
However, currently it has several limitations:
> # Normalized key computer is missing for some types, e.g., UUID
> # It only helps with unequal keys. When two keys are equal, it still requires random
accesses to do comparison.
