> The view engine has been creaky and cluttered. As shown by GeoCouch, adding new indexers basically involves copying the entire view engine and hacking the parts that are different. In short, the opposite of good engineering.
> Over the last couple weeks I've refactored the view engine and reimplemented the map/reduce view engine. These changes are 100% internal and no external behavior has changed. Performance is just a tiny bit better than trunk. I did do some playing trying to improve view update times and there are some dances we could do, but for the time being I wanted to keep the same general architecture for updates so that the changes are minimal.
