Tool for Customizing MapReduce Jobs.

[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

Depending on your exact needs, you may want to first check out http://docs.mongodb.org/manual/applications/aggregation/, which is actually distinct and faster than the Map/Reduce functionality built into MongoDB.  The MongoDB Aggregation Framework isn't as flexibile as the full Javascript-based Map/Reduce MongoDB implementation, but it offers plenty.

Do you have specific questions, queries, or use cases?  The group might be able to recommend one or the other if you provide more detail.
