Subject [jira] [Created] (HIVE-2115) Process residual predicate during automatic index query
Date Fri, 15 Apr 2011 23:48:05 GMT
Process residual predicate during automatic index query

                 Key: HIVE-2115
             Project: Hive
          Issue Type: Improvement
          Components: Indexing
    Affects Versions: 0.8.0
            Reporter: Russell Melick

During automatic use of indexes, we analyze the query predicate to pull out what we can use
the index on.  Not all of the predicate can necessarily be processed with a single index.
 Currently, we return the residual predicate from the IndexHandler but do not process it further.
 We run the full original predicate on the index table.  Ideally, we would want to only run
the residual predicate so we don't have to do as much processing.
