Paul Joseph Davis commented on COUCHDB-523:
-------------------------------------------

I would say that Adam's array based approach is probably going to be more sensible as it allows people to more easily control the order in which the queries are processed in the case where someone wants to aggregate some sort of result across the multiple views.

For the response I think having a {"results": $array_of_results} wrapper is probably better as it allows for future changes more easily if we start annotating that response.

Just for fun, has anyone considered how this would integrate with _lists? Or if we people should be allowed to make queries on multiple views, and if so if they should or shouldn't be scoped to a design doc?

> It would be useful if I could do a single POST to a view to retrieve multiple ranges specified by startkey, endkey.
> The format could be as follows:
> { "ranges": [ { "startkey": "a", "endkey": "c" }, { "startkey":"g", "endkey":"z" } ] }
