Hi,
Right now some quite basic things are rather difficult in CouchDB. For
example, if we had a database with car objects that have brands and
models, there's no straightforward way of finding all the different
car models or brands. This could become very simple if there was a
possibility of grouping results by keys. This could be implemented in
the following way:
* View-objects could have an additional attribute, "group", which
would contain a function taking two arguments: a key and a list of
values
* After the map phase, the "group" function would be called on each
different key and the list of objects that had this key
* The reduce phase would be done after the group phase.
This could also work very well with view collation.
Cheers,
