Namit Jain commented on HIVE-735:
---------------------------------
+1 on this idea - this should bring down the scan volume substantially
> Queries should be optimized with pre-ordered column

> URL: https://issues.apache.org/jira/browse/HIVE-735
> Project: Hadoop Hive
> Issue Type: Improvement
> Components: Query Processor
> Reporter: He Yongqiang
>
> If a table has one or some pre-ordered columns and a query has
> filters(range/point) on these columns. Hive should take advantage of the
> order information, and only read the needed blocks instead of touching the
> whole file. And this will also be useful for sorted summary table index.
