The Akka Actor framework is designed to be a fast message processing system. In this talk, we will explain how, at Box, we have used this framework to develop a large scale job processing system that works on billions of data files and achieves a high degree of throughput and fault tolerance. Over the course of the talk, we will explore the usage of Akka framework’s Supervisor functionality to provide a more controllable fault-tolerance strategy, and how we can use Futures to manage asynchronous jobs.
