You don't need to GET the full document to retrieve the current revision. Y=
ou can just do a HEAD request and look at the Etag header, which contains t=
he document _rev.

I usually work with a CouchDB library which abstracts this away (I like cou=
chdb-python for scripting), but I guess they all use HEAD requests under th=
e hood.

I everyone

I could use some advice on CouchDB "Best Pratice" for deleting documents.

Lets say I know the id of some docs I want to delete, I still have to
retreive their _rev number before sending the DELETE. So, do I really
have to read(GET request) an entire document just to get its _rev or
should I create a _view to get _id + _rev pairs ?
Both ways seem non ideal to me, because why loading an entire document
just to read its _rev (it might be a really big doc and u might have a
lot of them) and why create a _view that will suffer from indexation
process, reading a single value is supposed to be quick ...
Or may be there is a way to get "just" the _rev from some doc _id that
I don't know about ?

Feel free to show me the way ... and let me know how u proceed ...

Fred
