This talk will help you build data mining and machine learning applications using Apache Giraph framework for graph processing. This talk is based on the "Practical Graph Analytics with Apache Giraph" book trying to be as hands-on as possible. Apache Giraph offers a simple yet flexible programming model targeted to graph algorithms and designed to scale easily to accommodate massive amounts of data. Originally developed at Yahoo!, Giraph now enjoys a diverse community of contributors from who's-who of Silicon Valley companies: Facebook, LinkedIN and Twitter.
