Subject scalabitily of the _changes feed
Date Tue, 27 Sep 2011 09:40:02 GMT
is it okay to register a huge number of listeners to the changes feed?

I notice that you can use a filter function, which gets passed the request
does this mean that the filter function will be called for each doc, for
each listener on the changes feed?
or are the results of each filter call cached so that it is possible to
efficiently register many listeners using the same filter function?

cheers, Dominic
