The Retainable Evaluator Execution Framework (REEF) is a Microsoft big data technology that works with the Apache Hadoop YARN resource manager. REEF is a framework to implement scalable, fault-tolerant runtime environments for computational models. With REEF, users can build jobs that utilize data from where it’s needed and also maintain state after jobs are done. REEF is believed to be well-suited for building machine learning jobs.
In August 2013, Microsoft announced plans to open source its Retainable Evaluator Execution Framework (REEF) technology.
