------------------------------------

So, I made PIG-6. BTW, I don't think PIG should be provides complex queries or a algebraic process library.

> 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.
