----------------------------------
I've added some review board comments; I'll probably have some more once we've
resolved these.
> Update bitmap indexes for automatic usage
> -----------------------------------------
>
> Key: HIVE-2036
> URL: https://issues.apache.org/jira/browse/HIVE-2036
> Project: Hive
> Issue Type: Improvement
> Components: Indexing
> Affects Versions: 0.8.0
> Reporter: Russell Melick
> Assignee: Syed S. Albiz
> Attachments: HIVE-2036.1.patch

>
> HIVE-1644 will provide automatic usage of indexes, and HIVE-1803 adds bitmap
> index support. The bitmap code will need to be extended after it is
> committed to enable automatic use of indexing. Most work will be focused in
> the BitmapIndexHandler, which needs to generate the re-entrant QL index
> query. There may also be significant work in the IndexPredicateAnalyzer to
> support predicates with OR's, instead of just AND's as it is currently.
