Okay... I think I finally understood some of your perspective. The
aggregations are seen as a table. Since each type of aggregation can
aggregate different type of functions/metrics, the columns can potentially
be different.. So from such a perspective, HBase looks like a good option.
Also, the rowkey approach helps to fold all kinds of things into it and
serves as an index for the cube data.
Now I understand, what Julian was coming from.
This is good - at least I got to understand the perspective from which you
are looking at the problem. Thanks!
