Yes. For me it's a feature, rather than a bug, that couchdb databases are
completely isolated from each other. Maybe you should consider lumping
everything into one database.


>> I can understand that couchdb DBs are completely isolated, I also agree that logically it is ok. But since there is no other layer we can use within a DB for modeling, I think operations on multiple databases are desired.

It does seem that putting something I need into one DB is the only way. Maybe it is acceptable since couchdb works incrementally, so performance won't be a problem even there is a large number of records because of combining multiple DBs into one ....
