Subject [jira] Commented: (HIVE-417) Implement Indexing in Hive
Date Wed, 30 Jun 2010 21:28:55 GMT

    [ https://issues.apache.org/jira/browse/HIVE-417?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12884067#action_12884067

Namit Jain commented on HIVE-417:
---------------------------------

Looking at the patch (not yet in detail) seems to suggest the following:

1. The index file can only be a text file.
2. PROJECTION index is not used - I mean, to start, can we just get the basic COMPACT+SUMMARY
and only support that.
