Couchbase _changes feed equivalent

[Stanley Iriele]

What is the couchbase equivalent of the changes feed?...just to be clear I
am using couchdb but I am asking for a friend. I am familiar with the
changes feed enough but it seems like this has been hidden away from the
developer in couchbase. ...how would someone achieve the same behavior from
couchbase?...Any one with insight on this would be greatly appreciated.
