Subject [jira] [Created] (HIVE-7818) Support boolean PPD for ORC
Date Thu, 21 Aug 2014 00:39:33 GMT
Daniel Dai created HIVE-7818:

             Summary: Support boolean PPD for ORC
                 Key: HIVE-7818
             Project: Hive
          Issue Type: Improvement
            Reporter: Daniel Dai

Currently ORC does collect stats for boolean field. However, the boolean stats is not range
based, instead, it collects counts of true records. RecordReaderImpl.evaluatePredicate currently
only deals with range based stats, we need to improve it to deal with the boolean stats.
