Hi Justin, Yes.I agree that if we have shared store, we don't need to replication. But it would good option to have jdbc (shared store) for lock only to avid the split-brain issue as configuring 3 pair is not suitable for small environment and 3 pairs add lot of complexity. Thanks for the detail

I'm not aware of any plans to implement what you suggest here. It seems to me that if you want to mitigate the risk of split brain and you have access to shared storage then you should just use a shared store configuration instead of replication. The main benefit of replication that you don't need

Hi, For small environment to use High availability, it is often difficult to setup 3-pair cluster to avoid split-brain. It would be great if artemis master and slave use data replication and use shared store only for lock and providing HA . So anytime, master/slave verifies and gets lock before t
