A Super Short on the Youporn Stack - 300K QPS and 100 Million Page Views Per Day

Eric Pickup from Youporn.com posted on a news group that Youporn is now 100% Redis based and will soon be revealing more about their architecture at the ConFoo conference. Some stunning, but not surprising numbers were revealed:

  • 100 million page views per day
  • A cluster of Redis slaves are handling over 300k queries per second.

Some additional nuggets:

  • Additional Redis nodes were added because the network cards couldn't keep up with Redis.
  • Impressed with Redis' performance.
  • All reads come from Redis;  we are maintaining MySQL just to allow us to build new sorted sets as our requirement change
  • Most data is found in hashes with ordered sets used to know what data to show.   
    • A typical lookup would be an zInterStore on: videos:filters:released, Videos:filters:orientation:straight,Videos:filters:categories:{category_id}, Videos:ordering:rating
    • Then perform a zRange to get the pages we want and get the list of video_ids back. 
    • Then start a pipeline and get all the videos from hashes.
    • Do use some key/value lookups and some lists, but the majority of our operations are using the above pattern.

Not much to see yet, but hopefully we'll learn more after their talk.

Which client lib you are using for REDIS and how are you handling partitioning?
