Subject [jira] [Commented] (HIVE-5692) Make VectorGroupByOperator parameters configurable
Date Mon, 11 Nov 2013 18:39:17 GMT

    [ https://issues.apache.org/jira/browse/HIVE-5692?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13819191#comment-13819191

Gopal V commented on HIVE-5692:
-------------------------------

[~ashutoshc] I  ran into this in our tests and the fastest version of those settings were
to flush 100% of keys every 10k keys.

I have reviewed that patch and it looks good enough. The default values for those variables
are still up for discussion, but now for us it could be set in hive-site.xml instead of being
hard-coded.
