I hear Google uses a lot of Python, and a lot of NoSQL.

We probably use Perl a relatively larger amount, and we rolled our own
NoSQL database. A modest amount of our perl became a much larger pile
of XS, once we were done experimenting with the algorithms.

I know people run massively parallel Postgresql databases, but they
don't do what a search engine wants out of a database. Serving ads,
sure. But not all the weird stuff we do to crawl, index, and serve
