AnyEvent::CouchDB is a non-blocking CouchDB client implemented on top of the AnyEvent framework. Using this library will give you the ability to run many CouchDB requests asynchronously, and it was intended to be used within a Coro+AnyEvent environment. However, it can also be used synchronously if you want. Its API is based on jquery.couch.js, but we've adapted the API slightly so that it makes sense in an asynchronous Perl environment.
