Subject [jira] [Updated] (HIVE-11822) vectorize NVL UDF
Date Thu, 08 Oct 2015 12:49:26 GMT

     [ https://issues.apache.org/jira/browse/HIVE-11822?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Takanobu Asanuma updated HIVE-11822:
------------------------------------
    Attachment: HIVE-11822.1.patch

I uploaded an initial patch for vectorized NVL. This patch also includes qtests for NVL and
Coalesce. Please could you review it?

While reading the codes, I realized we can completely reuse VectorCoalesce for vectorized
NVL. So I didn't write VectorNvl in this patch. I think there are not many overheads even
if we use VectorCoalesce as VectorNvl. What do you think?
