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

Hi 
please notice that tpch queries were translated into pig latin and are available since july'2011 for download from my homepage https://sites.google.com/site/rimmoussa/research.

Also for avoiding join operations costs, I've combined all .tbl files into one file;

cheers,
Dr. Rim Moussa

> For a class project we developed a whole set of Pig scripts for TPC-H. Our goals are:
> 1) identifying the bottlenecks of Pig's performance especially of its relational operators,
> 2) studying how to write efficient scripts by making full use of Pig Latin's features,
> 3) comparing with Hive's TPC-H results for verifying both 1) and 2).
> We will update the JIRA with our scripts, results and analysis soon.
