This epic aim to implement a new Quorum Vote mechanism for AMQ with the objectives:
- to make it pluggable
- to cleanly separate the election phase and the cluster member states
- to simplify most common setups in both amount of configuration and requirements
A proposal of steps to be followed to get this is:
- abstract away the current quorum vote: it requires extra-care because the
logic is mixed together with the replication/clustering behaviour - refactor it in order to separate election phase and cluster member states
- 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:
- a clean upgrade path for current HA replication users
- deprecate or integrate the current HA replication into the new version
