In this presentaion I will present EventMachine, a ruby gem primarily written by Francis Cianfrocca. I will take listeners from having no knowledge of EventMachine to implementing a simple Key-Value store in the vein of Memcache. Along the way, we will:

  • Learn the basics of programming using EM: What the event loop is, and what objects you can add to be processed during the loop
  • Create periodic and one-shot timers
  • Create a simple hello world tcp server
  • Learn about the various callbacks available to an EventMachine server
  • Learn tips and tricks to improve your server’s scalability

After implementing this simple key-value server, I will present a fully featured replacement of BackgroundDRB, written using EventMachine. I will outline various features of this server and how EventMachine made the system extremely simple.
