Subject [02/14] couch-httpd commit: updated refs/heads/1994-merge-rcouch to d936233
Date Thu, 13 Feb 2014 03:09:58 GMT
couch_replicator: add replication using changes in a view

Instead of a database, the replicator can now filter the documents using
a view index. All documents having a key emitted in the view can be
replicated.

View parameters can be used. Which means that you can replicate results
corresponding to a key in a view or a range.
