[jira] [Commented] (COUCHDB-1529) Add API to find the deleted branches of a doc's rev tree

["Jens Alfke (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/COUCHDB-1529?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13448249#comment-13448249 ] 

Jens Alfke commented on COUCHDB-1529:
-------------------------------------

Note: It's possible to do this currently by iterating through the database's entire _changes feed, since it includes deletions. That's expensive, though.

> There's no efficient way to discover the complete revision tree of a document. API options like ?open_revs=all or ?conflicts will only return active/undeleted revisions; it won't discover deleted branches resulting from already-resolved conflicts.
> There should be an extra option, like "?include_deleted=true", to use along with open_revs to tell it to return even deleted leaf revisions.
