Well, but how scalable is this? If I understand it well, when I have 1000 articles in my DB, cayenne 2.0.x will FULLY query for ALL of the 1000 articles on EVERY page change, but will take only PKs from the result rows beyond 1st page? This seems to me like a pretty extreme db server load case.... If I imagine having a portal with thousands of people per day browsing through articles... In success stories, there are some companies that manage pretty big dbs with cayenne, how do they manage these tables with paginated queries? Or am I missing smthing?
