Paul Joseph Davis updated COUCHDB-415:
--------------------------------------
Skill Level: Committers Level (Medium to Hard)
> View sorting
> ------------
>
> Key: COUCHDB-415
> URL: https://issues.apache.org/jira/browse/COUCHDB-415
> Project: CouchDB
> Issue Type: Wish
> Affects Versions: 0.9
> Reporter: Nils Breunese
>
> I'd like to be able to sort the output of a view. I have a view that
> generates a list of event objects with start and end timestamps (and some
> other data). I emit this data using the end timestamp as the key, because
> that is what I want to use for my ?startkey=... query. But I'd like the
> results to be sorted by the start timestamp. I understand this is not
> currently possible using regular CouchDB views.
> The CouchDB Users mailinglist suggested to use couchdb-lucene, as that does
> offer the option to sort on any indexed field. I'm trying that route now, but
> it feels like overkill to add a full-text indexer to CouchDB just to be able
> to sort the output of my view.
> Some soundbites from the IRC channel when I brought this up:
> ----
> <rnewson> breun: jan___: in this case the data to sort on is known at map
> time, so an extension to emit to support multiple keys (with separate btrees)
> would do it. not sure how much effort that is, though.
> <rnewson> sorting at query time feels infeasible.
> <jan____> rnewson: I think davisp had something like that working back in the
> day. i.e. alternate sort oder. davisp?
> <rnewson> jan___: I missed that, but it sounds reasonable at emit time.
> <davisp> I think its this one:
> http://github.com/davisp/couchdb-old-patches/tree/view-sort
> ----
> I would love to have view sorting native in CouchDB.
