Caching is a full row?

[Paul Prescod]

Am I correct in my understanding that the unit of caching (and
fetching from disk?) is a full row?

                cf = cacheRow(filter.key);

Also, that the thing that is cached is just the top level columns?

            cached = getTopLevelColumns(new IdentityQueryFilter(key,
new QueryPath(columnFamily_)), Integer.MIN_VALUE);
