Thanks for working on this!

File be/src/runtime/types.h:

http://gerrit.cloudera.org:8080/#/c/24504/2/be/src/runtime/types.h@102
PS2, Line 102: is_uuid_(false)
Could you please explore the case when we add a standalone enum (TYPE_UUID), 
and in the backend we store the fixed 16 bytes inline in the tuple (like 
CHAR(N) or large DECIMALs)?

It might require a bigger code change. but I think the changes will be mostly 
trivial/mechanical, with AI it shouldn't be too hard. It would make read/write 
operations quite straightforward as well.
