public class ScaleOut
extends Object

This class demonstrates concurrent reading and writing with the U10 data set on the scale-out architecture. One thread writes the U10 data files, doing a commit after every file (this is not the fastest way to perform load, as it simulates incremental updates vs bulk load). Another thread asks for the number of "FullProfessors" every three seconds. You can watch the number of results rise as more data is loaded.
