Youporn.com is now a 100% Redis Site
That's porn for database geeks: 100 million pageviews per day, 300k requests per second against Redis.<p>The way they use MySQL is also interesting IMHO: they populate a relational database in order to be able to build new indexes in the Redis side, using the relational DB for the stuff it is best at, generating new "views" of the data easily.<p>(Relational DBs are also good to do a zillion more things of course.)
