MapReduce - MongoDB - Aggregation

[Vishal Mody]

Hi,

I am looking into using MapReduce Aggregation framework on top of my stored data in MongoDB in different collections.

I want these MapReduce jobs Aggregation logic more customizable such that it can be changed easily based on business rules. Is there any way you can extract that MapReduce functionality or any tool which makes this possible.

I am a beginner MongoDB user so pardon my some terminology or understanding of perfect concept behind MapReduce/MongoDB and if was not clear in my question. 

Thanks,

Vishal Mody

Hi Vishal,

I just wanted to clear up any possible confusion- Map Reduce and the
aggregation framework are two separate commands; the first uses
Javascript and the latter uses C++.  Here is the documentation for
both:
- http://www.mongodb.org/display/DOCS/MapReduce
- http://docs.mongodb.org/manual/applications/aggregation/

Could you give us more information about what you're trying to do?
