SASReduce - An implementation of MapReduce in BASE/SAS ®
David E. Moors · 2014
This paper will explain how a simple processing framework created by Google, and more recently popularised by the Open Source technology Hadoop, can be replicated using cornerstone SAS technologies such as BASE/SAS ® , SAS/MACRO ® and SAS/CONNECT ® . The paper will explain how, out-of-the-box, the SAS DATASTEP ® can replicate the ‘Map’ function, and we’ll discover how well established SAS Procedures can be used to create ‘Reducer’ like functionality. We’ll also see how Parallel Processing data across multiple SAS Sessions using MP/CONNECT ® can replicate MapReduce’s approach to data processing.
