Subject [jira] Commented: (HIVE-417) Implement Indexing in Hive
Date Wed, 15 Apr 2009 16:20:14 GMT

    [ https://issues.apache.org/jira/browse/HIVE-417?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12699258#action_12699258
] 

Prasad Chakka commented on HIVE-417:
------------------------------------

We already have code (based on early version of hive) that does the important work. But we
need to integrate this with Hive QL and determine the candidate indexes for a query. Also
a way to create buckets (both hash and range) would really speed up the index processing.
I didn't realize but predicate pushdown makes things simpler.
