    Description

      This epic aim to implement a new Quorum Vote mechanism for AMQ with the objectives:

      1. to make it pluggable
      2. to cleanly separate the election phase and the cluster member states
      3. to simplify most common setups in both amount of configuration and requirements

      A proposal of steps to be followed to get this is:

      1. abstract away the current quorum vote: it requires extra-care because the
        logic is mixed together with the replication/clustering behaviour
      2. refactor it in order to separate election phase and cluster member states
      3. implement a RI version using a specific consensus provider (eg zookeeper, jgroup-raft)

      About the last point, we need extra care to correctly handle the community requirements to get it accepted.

      Post-actions to help people adopt it, but need to be thought upfront:

      1. a clean upgrade path for current HA replication users
      2. deprecate or integrate the current HA replication into the new version

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
