---------------------------------------------------------
Another possibility could be to define a number N which is a rank; everyone higher than N
does NOT response.
Example: we have {A,B,C,D,E,F,G}. If we set N=3, then that means that A, B and C will
respond, but nobody else.
This is the same as saying the oldest N members should reply.
If A leaves, then we'll have view {B,C,D,E,F,G} and with N=3, B, C and D will
respond.
N <= 0 means everyone will reply.

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.
