Someone who should know told me that LinkedIn runs its main application on Oracle. So when I saw the press release about MySQL being their database, I read carefully, and they are not very specific about exactly what MySQL is used for. Depending on how you read it, you could argue that they left open the possibility that the main application database is not MySQL, and the MySQL deal is for something peripheral.
Now, this is nothing but a rotten rumor and I will probably burn in hell for spreading it, but I’d like it to be debunked if it’s false. What is LinkedIn’s main database server? Anyone have the provably correct answer?
PS: I see that LinkedIn is “seeing daily downloads of approximately 200 million.” I didn’t know it was downloadable. I’ve been missing out! Where can I download it?

From this http://www.sun.com/customers/servers/linkedin.xml, Oracle is the main DBMS and they replicate changes (some or all?) to MySQL.
According to the presentations at JavaOne this year, they use both Oracle and MySQL … but the presentations don’t show the exact roles of either. Summaries & links to presentations here.
All I can find about the LinkedIn arch says “Oracle and MySQL as dbs”:

That’s truly some interesting slides from linked-in.
I guess it’s hard for them to move away from current architecture,
not they are hiring Sr. Oracle DBA :)
