My apologies for asking a probably rather stupid question ..
Docs in my database are events. An event has a category name, a time
stamp and lots of other details. I am looking for the most recent
event.
I started with something like
function (doc) { // map
emit(doc.name,doc)
}
function (ks,vs,rr) {
var maxdoc = max_timestamp(vs);
return maxdoc;
}
Although I'm reducing considerably, couchdb complains that I'm not
reducing hard enough :-)
(* Btw, what is actually the "reduce" limit? Do attachments count as well? *)
Then I tried something like
function (doc) {
emit(doc.name,{ "_id" : doc._id, "ts" : doc.timestamp});
}
and with a "virtually" unchanged reduce function. Now I'm below
couchdb's reduction limit. However, this view does not return the most
recent document I was looking for but the "id" of that document.
I had some hope that query parameter "include_docs=true" would do the
magic (that's why I used "_id" as property name). But then I learned
that "include_docs" is not supported for "reduced" views which took me
by surprise. What could be the rational for this behaviour?
In summary:
* Is there a way to get the "most recent" document via a view?
