----------------------------------------

             Summary: Add flag to the changes API to return only new changes
                 Key: COUCHDB-1501
                 URL: https://issues.apache.org/jira/browse/COUCHDB-1501
             Project: CouchDB
          Issue Type: New Feature
          Components: JavaScript View Server
    Affects Versions: 1.2
            Reporter: Daniel Gonzalez
            Priority: Minor


As discussed in this thread: http://mail-archives.apache.org/mod_mbox/couchdb-user/201206.mbox/%3CCAAOi-OHB6%3DYu%2Bt%3DWkiFAypQAfnv%3DQd-PL4tELZNL1C1-TQvtWw%40mail.gmail.com%3E

I copy paste part of the conversation.

I am subscribing to the _changes API. My database is quite big, and each time I restart my
client, I get all old notifications. I only need the new notifications, since the moment that
I subscribe to the feed.

I have seen that there is a "since" parameter, but this is not helping me further, because
I do not know what is the last document sequence number. So I would need one of the following:

- a method to get the last sequence number to use as value for "since"
- a flag to tell the _changes API to just give me the changed *from now on*. This would be
the most clean solution, since it saves me a request to get the since parameter (which can
be outdated anyway very fast). Is there something like this?

---

I ended up going the GET /dbname route
I guess there is no specific flag for the _changes API to request future changes...
