Mongo Map/Reduce

[Maruthi Shanmugam]

Hi,

We need to understand the Map/reduce limitation in sharded environments. 

Can you please let us know the same? We are planning to use across 100 clusters.

Hi Maruthi -

by limitations, are you worried about performance issues?  If you could parallelize the map-reduce operation, or depending upon what you want to do, perhaps you can use the aggregation framework.
