Hi Andrew,
I think you mentioned it before when I had questions about aggregation
using RegionObserver. I checked it out but since our use case is quite
simple and there is only one aggregation level (country), we went with the
coprocessor.
However, someone did post a question about something similar to an OLAP
cube and I recommended it to him with your recommendation :)
