  I got an email today explaining an approach to stats logging that quite suprised me in terms
of its complete obviousness (that I had failed to see) and its complete awesomeness.
  
  The basic idea: pre-reduce. The use case as described below is for stats reporting and the
idea is that after we've figured out to use _bulk_docs and buffer some number or time period
of log data before inserting, we can go one step further and pre-reduce that data down into
a single doc for insertion. I can already see people implementing support via their favorite
language binding support to even use the same map/reduce functions from CouchDB as a pre-processor
for creating summary docs on input.
