Sergey Shelukhin commented on HIVE-15468:
-----------------------------------------
It doesn't vectorize the pipeline... that I guess is the part that is not
supported. I was just clarifying :)
> Enhance the vectorized execution engine to support complex types

> Project: Hive
> Issue Type: Improvement

> Reporter: Chao Sun

>
> Currently Hive's vectorized execution engine only supports scalar types, as

> To be complete, we should add support for complex types as well.
