Has anyone ever looked at OLAP Cube processing on Pig or MapReduce? This feature should be beneficial for normal businesses (probably not web scale). I find it pretty simple provided that we can work on relational abstraction (but might not scale well on really big datasets). I have done a sketch on how I think it should look like here http://wiki.apache.org/pig/PigOLAPSketch . Welcome for all comments/suggestions.
