> 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can be outdated anyway very fast).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?
