             Summary: Use consensus for some subsystems
                 Key: JGRP-1911
                 URL: https://issues.jboss.org/browse/JGRP-1911
             Project: JGroups
          Issue Type: Feature Request
            Reporter: Bela Ban
            Assignee: Bela Ban
             Fix For: 3.6.2


Provide options for several subsystems to run with consensus, e.g.
* {{SEQUENCER}}
* {{CENTRAL_LOCK}}
* {{COUNTER}}
* {{TOA}}
* Clustered singletons etc

For example, with the current impl of distributed counters ({{COUNTER}}), the same counter can be available multiple times if we have a split brain. It is currently up to the user to merge counters with different values after a split brain heals.
This is OK, but we should provide a second implementation, based on jgroups-raft, which uses consensus to determine the counter maintainer in a split brain scenario. This will forfeit availability in favor of consistency.
