Scaling Rails

Episode #18 - Scaling Your Database - Part 2

In this second screencast we start out by learning the differences between the myISAM and InnoDB database engines for MySQL. Next we learn how to scale a write heavy database by using Master Master replication, and how we might configure this to work with our Rails application. Lastly we’ll figure out how to shard our database by spliting our tables between multiple databases and show how both New Relic and eBay take advantage of this technique.
