Subject [jira] [Updated] (HIVE-4823) implement vectorized TRIM(), LTRIM(), RTRIM()
Date Mon, 23 Sep 2013 17:41:02 GMT


Eric Hanson updated HIVE-4823:

    Attachment: HIVE-4823.2-vectorization.patch

Rebased this patch on the latest vectorization branch. Verified that junit tests pass. Did
ad hoc end-to end tests for the TRIM(), LTRIM() and RTRIM() functions and verified that they
work in vectorized mode.
