I was wondering if any of you know what database does twitter use?
I read this article but I still don't get an answer.
Since twitter gets so much daily traffic I just wanted to know what database they use.
I know Google uses their own custom in-house solution they created from scratch, instead of storing their data in SqlServer, Oracle or Terradata, so I was wondering if maybe Twitter did the same or do they use Oracle or Terradata for their data storage so they could be able to serve up so many daily transactions.
Thanks for any help you can give me on this question.
