Subject RE: Reduce overflow errors when number of documents >= 10?
Date Tue, 02 Jul 2013 14:20:37 GMT
There are 3 views. Two of the views I don't need reduce functions and so I
have tried the system with no reduce.js, an empty reduce.js file, and a
reduce function that just returns null.  The third reduce function looks
like this:

 function(keys, values) {
	return sum(values);
}

- N

Is that the only view in that design doc? Or is there another view with a
reduce function?
