Subject [jira] [Commented] (COUCHDB-1737) _changes feed for views
Date Thu, 28 Mar 2013 01:39:16 GMT

    [ https://issues.apache.org/jira/browse/COUCHDB-1737?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13615965#comment-13615965

Benoit Chesneau commented on COUCHDB-1737:
------------------------------------------

[~klaus_trainer] For now the view filter in couchdb is passing the map functions on all the
changes just like a filter function so it's not really efficient on a big number of document
, especially when you start from 0.

The feature asked here would notify about changes in the index, aka "real" view changes and
all changes wil be indexed just like a db.
