Subject [jira] [Commented] (HIVE-5758) Implement vectorized support for NOT IN filter
Date Sat, 23 Nov 2013 00:25:36 GMT

    [ https://issues.apache.org/jira/browse/HIVE-5758?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13830452#comment-13830452
] 

Eric Hanson commented on HIVE-5758:
-----------------------------------

It turns out that the parser transforms

col NOT IN (<list>)

to

NOT (col IN (<list>))

So when support for a IN as a Boolean expression is added, this should just work.

> Implement full, end-to-end support for NOT IN in vectorized mode, including new VectorExpression
class(es), VectorizationContext translation to a VectorExpression, and unit tests for these,
as well as end-to-end ad hoc testing. An end-to-end .q test is recommended.
