> HIVE-1226 added support for WHERE rowkey=3.  We would like to support WHERE rowkey BETWEEN 10 and 20, as well as predicates on non-rowkeys (plus conjunctions etc).  Non-rowkey conditions can't be used to filter out entire ranges, but they can be used to push the per-row filter processing as far down as possible.
