Edward J. Yoon commented on PIG-210:
------------------------------------
So, I made PIG-6. BTW, I don't think PIG should be provides complex queries or
a algebraic process library.

> Issue Type: New Feature
> Components: data
> Reporter: John DeTreville
>
> I believe that Pig stores its tables in row order, which is less efficient in
> space and time than column order in a data-mining system. Column stores can
> be more highly compressed, and can be read and written faster. It should be
> possible for clients to store their tables in column order.
