Recommendation Engines with Redis and Ruby

A session at RubyConf 2013

Friday 8th November, 2013

2:05pm to 2:50pm (EST)

A recent client asked me to build a recommendation engine for them. Coming into this with a basic knowledge of statistical math, we ultimately built a relatively simple recommendation engine in Ruby. The design makes heavy use of Redis Sets, Lists, and Hashes in order to greatly reduce the number of SQL queries to provide recommendations.

This talk will be a case study of sorts discussing object-oriented techniques in building a scalable service as well as how we leveraged Redis to both simplify and expedite some of the operations that would have otherwise brought the service to a crawl.
