Jason Dere commented on HIVE-16568:
-----------------------------------

This might increase memory overhead, certainly in the case of complex types 
where the list/map/struct needs to be traversed/converted. But I'm not sure how 
else to provide the complex types, unless we make clients use the 
ObjectInspector interface to access the various fields of the complex types.

Will look into doing more tests.
