Subject [jira] [Commented] (HIVE-5761) Implement vectorized support for the DATE data type
Date Tue, 26 Nov 2013 04:54:35 GMT


Teddy Choi commented on HIVE-5761:

I would like to take this issue, following to HIVE-5581. They have much in common. I will
create vectorized versions of UDFDate, UDFDateAdd, UDFDateDiff, UDFDateSub, UDFDayOfMonth,
UDFMonth, UDFToString, UDFWeekOfYear, UDFYear.

> 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.
