I have a timeseries data and I am looking for capabilities to store
and aggregates the events on such level granularity: YEAR | MONTH | WEEK
| DAY | HOUR.
I need functionality like sum() , average().
For example to calculate average for event X which was at 14:00 PM every
sunday during JANUARY.
1) I see it like Olap Cube solution , Am I right?
2) Can someone point me on Olap Cube open source project over hbase?
