Hari Sankar Sivarama Subramaniyan commented on HIVE-5760:
---------------------------------------------------------
[~mmccline] A couple of high level qns :
1. How do you plan to enforce the maximum possible length of the datatype.
2. Does cast varchar to and from other data types work well with the patch. Can
you add some test cases.
Thanks

> Add support to allow queries referencing VARCHAR columns and expression
> results to run efficiently in vectorized mode. This should re-use the code
> for the STRING type 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 string operations.
