As I understand, the situation you describe above never happens in practice with CouchDB. A second PUT to the same document _id will always require the _rev attribute, so there's no way to overwrite a previous update by accident. This is one of the best features of CouchDB for document-oriented persistency. -- Luciano Ramalho programador repentista || stand-up programmer Twitter: @luciano
