---------------------------------------
Attachment: (was: 0002-Create-the-couch_index-application.patch)
> Rewrite the view engine
> -----------------------
>
> Key: COUCHDB-1270
> URL: https://issues.apache.org/jira/browse/COUCHDB-1270
> Project: CouchDB
> Issue Type: Improvement
> Components: JavaScript View Server
> Reporter: Paul Joseph Davis
>
> 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.
