I think a fine way to add this information would be in the JSON view
response body itself, something like:
{"total_rows":1000,"offset":0, "update_seq": 1001, "rows":[
{"id":"1","key":1,"value":null},
...
This patch should be among the more trivial for a new Erlang / CouchDB
author to implement.
I see no reason not to add this feature. If anyone wants to implement,
and has questions or needs help getting started, the dev@ mailing list
is the place.
