When updating a document, is there any notion of submitting a

It seems like being able to specify that only some subset of the
fields in a
document should be updated would offer some efficiency benefits. I
guess I
had in mind some scenario where CouchDB would create the updated
record by
merging the existing revision with the new info and saving the
updated
revision, but I'm still new to CouchDB so I don't have a good sense
of whether
this tramples on any important concepts.
Nope, CouchDB does not support this at the moment. If you want to
make an update
you have to send the entire document each time.
There is some discussion among CouchDB users and developers about
the benefits
of partial updates but it seems the real sticking point so far is
deciding on
the mechanism for enabling this. It seems the rough consensus at
this point is
that whatever method we use be something that is standardised,
either through a
standards body or de facto within the larger JSON community.
Thanks for the response - and yeah, this is not a sticking point at
the moment but as systems start to ramp up this seems like a pretty
good way to make the back and forths much more efficient. Will be
looking forward to this being introduced at some point.
