Yeah, sorry I knew that but I was asking specifically about if there
was any caching within a row that is more granular than the whole row.
It looks to me like it doesn't just cache the columns you asked for,
but all columns in the row. This obviously has some interesting
implications for keys that are large "indexes" in a single row.
