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:

> Key: COUCHDB-841
> URL: https://issues.apache.org/jira/browse/COUCHDB-841
> Project: CouchDB
> Issue Type: New Feature
> Components: HTTP Interface
> Affects Versions: 1.0
> Reporter: Dirkjan Ochtman

> 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).
