Ashutosh Chauhan commented on HIVE-1643:
----------------------------------------
IndexPredicateAnalyzer was originally written for analysis of index predicates
(as name suggests). Since, it matched the use case here for hbase handler, we
used it here too. But, its not required that we keep using it. We can write a
new PredicateAnalyzer (may be extending from IndexPA) which can also process
ORs in some way if we want to. Or, else you can accept any combination of
filter conditions (i.e., do not use PA at all) and construct appropriate filter
list for HBase.
> support range scans and non-key columns in HBase filter pushdown

> 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.
