Teddy Choi updated HIVE-5761:
-----------------------------
Attachment: HIVE-5761.1.patch
I attached my draft implementation and tests. A date vector is putted on the
static WeakHashMap instance on DateUtil, so its type can be checked later.
However, I think vectors needs type data on implementation to support UDFs with
various input types.
> Implement vectorized support for the DATE data type

> 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.
