Since we're discussing large numbers of mobile clients: would it be
possible to do replication in "batches" from a client (i.e. not

My understanding is the big benefit of Google doing it on multiple machine
is that they are concurrently processing huge amounts of data in batch.

I am very new to couchdb - but wondering if the approach below could work.
1. Have one or more independent clusters of couchdb (start with 1 and add more
as needed).
2. Layout a DB naming scheme
3. Have an appropriate firewall/router/switch in front of the client
machines/network and have that r

Tha
map can be performed back in cluster mode? There is an average number of
computers that are running this operation?
For example, the map reduces done by Google on several machines in the
cluster?

You can also skip writing the reduce function, if you use the built-in '_count'
and/or '_stats' reduce function. Just pass that as the 'reduce' field of your
view and it will automatically perform a count of the number of rows that come
out of your map function for a given key. As Sean has point
