Bela Ban commented on JGRP-1181:
--------------------------------
One issue with only A, B and C responding is that we won't have physical addresses and
logical names for D, E, F and G ! This means that, when we want to send a unicast message
to G for instance, we have to fetch this first. This does NOT lead to incorrect behavior,
but I suggest to set return_entire_cache="true"
PING messages to entire cluster limit scalability.

Key: JGRP-1181
URL: https://jira.jboss.org/browse/JGRP-1181
Project: JGroups
Issue Type: Feature Request
Reporter: Jonathan Oddy
Assignee: Bela Ban
Fix For: 2.11
PING messages generate a response from every node that receives them. In a large cluster
this will lead to a large number of responses needing to be processed. Making PINGs
target-able (e.g. ping to only coordinators, ping to anyone with a view not matching
ViewID N) could significantly reduce the number of nodes responding to a request.
