Paul Joseph Davis commented on COUCHDB-1270:
--------------------------------------------
Now that this has been on JIRA for a while I'm gonna start asking for people to
raise objections to committing it. The feed back I've seen so far has been
positive and the only concerns voiced are in terms of things we should look at
moving forward. I'd be more than happy to wait if anyone else wants more time
to review it, but I'd like to make use of this relative lull in development for
this sizable of a change to land and get more widespread testing.

> 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.
