[jira] Created: (COUCHDB-987) use view functions to emit changes
use view functions to emit changes
----------------------------------
Key: COUCHDB-987
URL: https://issues.apache.org/jira/browse/COUCHDB-987
Project: CouchDB
Issue Type: New Feature
Affects Versions: 1.2
Reporter: Benoit Chesneau
Assignee: Benoit Chesneau
Fix For: 1.2
Attachments: view_changes.patch
Add the ability to use map view function to filter changes instead of duplicating the
effort in writing a filter function that does the same, which is
apparently done a lot.
Each time a value could be emitted, a change is returned. The url is :
http://127.0.0.1:5984/testdb/_changes?filter=_view&view=dname/viewname
On other advantage is that I can also use this in an external indexer.
Branch is available on my github repo :
https://github.com/benoitc/couchdb/tree/view_changes
diff has been attached.

Though I haven't tested your view_changes branch, I'd just like to give
my +1 on this anyway. It's definitely a good feature, and the interface
(i.e., url query parameter syntax) looks straightforward.
Thanks Benoit!

[jira] [Commented] (COUCHDB-987) use view functions to emit changes
Posted by "Michael Reuss (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/COUCHDB-987?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13266487#comment-13266487 ]
Michael Reuss commented on COUCHDB-987:
---------------------------------------
Thanks for this great feature that finally made it to me in 1.2 ;-)
I was able to find the tests that explain the usage, but alas, it doesn't work for me as expected: I don't see document deletions any more in the changes feed. Is that on purpose? I suppose, I can't just emit a key in my view for deleted docs. Could we add deleted documents to the _view filter or do I miss something in the intended use?
Thanks, Micha.
