We presented on Pig tonight at the Pittsburgh HUG. Here are the slides: http://squarecog.wordpress.com/2009/11/03/apache-pig-apittsburgh-hadoop-user-group/
The presentation takes a brief romp through "why a new language", followed by a summary of what various joins do and how they work, some highlights of what's being worked on, and a few ideas for potential research directions (the Pittsburgh HUG is leans heavily towards the academia). Enjoy, feedback welcome. -Dmitriy
