PlanOut4J

PlanOut4J is a Java-based implementation of Facebook's PlanOut, an A/B testing framework designed to conduct experiments on the web at scale. PlanOut4J makes it easy to express, deploy and maintain sophisticated randomized experiments and to quickly iterate on these experiments, while satisfying the constraints of large-scale Internet services with many users.

PlanOut4J's emphasis is to enable persons who don't necessarily have comprehensive engineering background create and maintain experiments easily. To that extent, we utilize PlanOut DSL wrapped into an intuitive YAML format. Here is a simple config file describing a trivial namespace (more about namespaces below)

Can just add @Loggable to private methods that we want to log.
