Hi all,

I'm running a test on CouchDB, this test generates documents in CouchDB
database and later randomly updates the documents. The parameter for the
update is: id of the doc and map<key, value> that indicates the fields of
the doc to update. It doesn't have any knowledge of the doc version and I
retrieved this information from CouchDB before updating. This is slow and
in multi-thread environment this approach causes a lot of update conflicts.

I have been reading about the update handler and it seems to me that this
could be a possible way to go. But I'm having difficulty to implement this
update function, can anyone give me an example of how to write such a
function that can update multiple fields in a document, the fields to be
updated is not predefined but randomly specified by the test application.

Thanks
