------------------------------------------
I am getting compile errors when I apply 1-4 and 5 (2nd one).

> We have a key cache but that doesn't help mitigate the expensive
> deserialization of the actual data to return.
> Adding a row-level cache should be fairly simple using a
> ConcurrentLinkedHashMap<String [key], ColumnFamily> structure. (We will only
> cache whole rows at a time, since already know how to query on those
> in-memory. This limits us to CFs full of narrow rows but that is a common
> enough use case to be worth tackling if it can be done simply enough.)
