Which Database does Google use?
After comparing MySQL versus PostgreSQBl, I am very curious to know about what database (if ever its Open Source ?) does Google use?
A very interesting article written by the founders of google can be found here: http://infolab.stanford.edu/~backrub/google.html which is on the Anatomy of a Search Engine.
We know that Python powers both Google’s URLserver and the crawlers. But what about their databases?
