Subject [jira] [Commented] (COUCHDB-1270) Rewrite the view engine
Date Fri, 09 Sep 2011 14:06:09 GMT

    [ https://issues.apache.org/jira/browse/COUCHDB-1270?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13101219#comment-13101219

Benoit Chesneau commented on COUCHDB-1270:
------------------------------------------

+1 for this patch. All tests are green. I think it's good to have it now in trunk and fix
last bits imo. 

@davis what is the status of couch_query_serrvers, how do you expect it? I find it odd to
have it in couchdb folder while most of the code of views are in couch_index in couch_mrview
now.

> 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.
