[jira] [Commented] (COUCHDB-987) use view functions to emit changes

["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.

> 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.
