* Incremental Map Reduce
- This is also strong right now. It could be faster, but so far it's
been fast enough.
I'd like to see built-in reductions for simple and commonly used
things like count, sum, average, etc. When used it would avoid 90%
of the current reduction costs.
* Alternate Storage and View Engines
- There are interested parties here, but I think we're hoping to
save this one until all the deeply subtle stuff Damien's working on
comes together.
I think alternate view and reporting engines are a great idea, and
I'd definitely like plug-ins for file attachment storage. Alternate
storage engines aren't something that need to wait on me.
Any idea how _external is going to work in a partitioned database? For
example, if _externals don't see a global update_seq, then mechanisms
that currently work for e.g. geo-indexing or FTS won't be cluster-wide.
