Subject [jira] [Commented] (COUCHDB-841) Support WebSockets in continuous changes feeds
Date Mon, 30 Jan 2012 18:36:11 GMT

Nathan Vander Wilt commented on COUCHDB-841:
--------------------------------------------

For those interested in this, I'd recommend tracking the progress of https://issues.apache.org/jira/browse/COUCHDB-986
too (or perhaps: instead). 

Server-sent events are a much better match for CouchDB's (one-way) _changes feed than , and
are much simpler to implement across the board since they're conceptually just a hybrid of
"longpoll" plus the long-lived connection benefits of "continuous" feed types. The EventSource
standard, while still a working draft too, has a bit more mature browser support than WebSockets:

> Just wanted to put this on the roadmap: it would be nice if continuous changes feeds
(and maybe some other things in CouchDB, not sure) could support WebSockets. WebSockets are
an emerging standard (there's no final spec yet) with implementations in both recent Chrome
and Firefox (beta) releases that allows servers to push information to the browser without
having to do polling (or longpolling).
