Did you know that YouTube, Flickr, Linden Labs, Technorati, Facebook, FeedBurner, StumbleUpon, Wikipedia, Digg, LiveJournal, del.icio.us, Yahoo (Finance) and many others have all selected MySQL as a database backend for their web operations?
e.g. Flickr is using MySQL to store ~2 Pb (1 Petabyte = 1024 Terabyte); storing more than ~470M photos with more than 4 billion queries per day…!
Coming from an enterprise software company delivering products which only integrate with the highest-end (perceived) commercial databases, I didn’t have the pleasure to try MySQL but recently I do… I am still in the very beginning of my learning curve and until now it have been a real pleasant surprise – mainly due to the database’s speed and ability to easily “scale-out” on low-cost hardware (sharding).
MySQL have the disruptive technology “smell” all over it and my premonition is that it will increasingly evolved to be “good enough” for a larger and larger segment of the market…
