-- Queries using part key can be EQ/IN
-- Queries on cluster key(s) may be chained as long as the preceding is EQ
-- The final cluster key may use GT,LT,GTE,LTE
--
-- Can sort on the SECOND column, but that means you would have to always
-- be able to specify the second column as EQ to get to the third column.
