Description

Currently it is possible for an URP to alter the response for an update. However an URP is placed after the DistrubutedUpdateRequestProcessor in the chain and adds information to its response the information is sent back in the response to the originating Solr Node and then ignored by the DURP. Thus the response to the user does not contain this info.

I propose that URPs are given the ability to merge the responses they sent back in each replica request, so that the DURP can then add the merged responses to the user response.
