Subject [jira] [Commented] (HIVE-5761) Implement vectorized support for the DATE data type
Date Wed, 29 Jan 2014 21:56:12 GMT

    [ https://issues.apache.org/jira/browse/HIVE-5761?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13885867#comment-13885867

Jitendra Nath Pandey commented on HIVE-5761:
--------------------------------------------

The patch needs to be rebased to latest trunk. HIVE-6178 and HIVE-6303 address the vectorized
reader and writer for DATE, so this patch can just focus on DATE expressions.

> Add support to allow queries referencing DATE columns and expression results to run efficiently
in vectorized mode. This should re-use the code for the the integer/timestamp types to the
extent possible and beneficial. Include unit tests and end-to-end tests. Consider re-using
or extending existing end-to-end tests for vectorized integer and/or timestamp operations.
