> See observation in parent:
> # We are guaranteed to be passed KVs of the same row
> # There'll be at most one version for each column
> #1 allows us to completely avoid comparing the row keys.
> #2 Let's us do exact searches for columns. Allowing us to simplify the code - and save a bit more performance.
