I've written a bit here before about giving up on traditional relational databases for gathering, storing, and analyzing game metrics data. All three steps have serious scalability issues for the "one big machine" model.
However, SQL is often much more pleasant to write analytical queries in than, say, raw Java (or C++ or Python or...). So progress on a hybrid MapReduce/SQL system based on Hadoop and PostgreSQL is pretty interesting. I haven't had a chance to read too far into the announcements, or research the project itself, but it sure sounds interesting.
