Hello, I plan to use ravendb for time-series data. Is it possible to chain output of one map-reduce to another map-reduce. Say for example - I create a map-reduce to create daily aggregation. Then I use another map-reduce on the previous results to get fortnightly aggregation.
In both of the cases, I will like to have incremental map-reduce.
If there is an example of this kind of scenario please do point to me.

Hello, Thanks for your reply I read your answer, there is something like out in MondoDB, is that what you mean by saving aggregations as documents. (a new collection) What if there is another change in the base data, is there a mechanism by which I can do upsert , I mean do the incremental thing
