Subject [jira] [Commented] (HIVE-5978) Rollups not supported in vector mode.
Date Wed, 11 Dec 2013 09:43:07 GMT

    [ https://issues.apache.org/jira/browse/HIVE-5978?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13845228#comment-13845228

Lefty Leverenz commented on HIVE-5978:
--------------------------------------

Oh, just realized the wiki has a vectorization design doc now:  [https://cwiki.apache.org/confluence/display/Hive/Vectorized+Query+Execution].
 It links to HIVE-4160 for the complete doc, very helpful.

ROLLUP isn't in the list of supported data types and operations, so perhaps its current lack
of support is implied.  Should there be a list of supported aggregates?

> Rollups are not supported in vector mode, the query should fail to vectorize. A separate
jira will be filed to implement rollups in vector mode.
