NREL has released open source Databus on github for time series data
NREL has released their open source databus. They spin it as energy data (and a system for campus energy/building energy) but it is very general right now and probably will stay pretty general. More information can be found here
http://www.nrel.gov/analysis/databus/
The source code can be found here
https://github.com/deanhiller/databus
Star the project if you like the idea. NREL just did a big press release and is developing a community around the project. It is in it's early stages but there are users using it and I am helping HP set an instance up this month. If you want to become a committer on the project, let me know as well.
Later,
Dean

That one.
Essentially replicating a multi dimensional cube; a fact table with dimensions and aggregates of the fact properties calculated for the dimension values, including hierarchical dimensions such as time and location.
I'll try to keep an eye on what your doing :)

When you say aggregates, do you mean converting 1 minute data to 15 minute data or do you mean summing different streams such that you have the total energy from energy streams A, B, C, etc.
Ps. We are working on supporting both….there is a clusterable cron job thing in place right now that does some aggregation already but there is another in the works for moving higher rate data to lower rates.

Hi Dean,
Does this handle rollup aggregates along with the time series data ?
I had a quick look at the links and could not see anything.
