Subject [jira] [Commented] (COUCHDB-1296) _changes style feed for database create/delete

Sam Bisbee commented on COUCHDB-1296:
-------------------------------------

@Jan: Sorry, not sure I follow you. You closed this ticket but now think it's a good idea?
Or...? :)

Also, one possible solution to this is to have CouchDB store database data in a database (ex.,
_local). Then we get the _changes feed for free. Don't know if that would be any easier to
build than hooking into the existing on database create/delete functions.

Currently if you want to watch the _changes feed or start replication jobs for certain types
of databases (say they're name spaced) you have to get /_all_dbs and then poll it to check
for changes, requiring a full array scan.
> This feed would allow me to hit /_all_dbs once and then get updates without hitting /_all_dbs
every second and scanning a potentially large array.
