Can I query a view in CouchDB using mapreduce?

I have this problem that I think would require me to do multiple(two) mapreduces to get the expected result. Is this possible in Cou开发者_如何学GochDB? If not, A are there other database engines that might support this?

No. You could try Couldant hosting, which support map-reduce chaining, but that would lock you into that platform, as far as I can tell.

If a delay is acceptable, you may use an asynchronous process to feed the view data back into CouchDB as input for the second view.
