Description

Would like to request for a feature of creating a design document to be associated with only one document.
Currently the view function function(doc) it iterates over all documents in the database and one is required to check for either _id or create a type and check for it in the view.
In my use of couchdb i have lot of documents with large size and so running of a view takes one and in some case couch crashes with following

Now i agree that my document may be too big, and i know which one cause the problem it would of immense help if instead of going through each document in the view function i can pass the doc._id to the view function or the view is associated somehow with a document and runs for only that document.

That will solve one of my issues in terms of view performance and memory requirements in the case that is a large document but i have no view associated with it and i have smaller docs that contain extracted content of the large doc on which i want to run views then if the view is associated with a document it will never load the large document.
