Questions on Config-Sync between mates in HA Group and Replication
It appears that when config-sync is enabled in a HA-Group and Replication mates, it is provisioning additional MessageVPN and Queues. I have a few questions on the same:
- As it is provisioning the additional VPN and queues, does it mean config-sync between mates in a HA-Group and Replication Group is asynchronous?
- If it is Asynchronous, how durable it is when one of the node/site crashes and fails over to other node/site? Should we expect a message loss ?
- If it is synchronous, does it acknowledge only when message is persisted on other node/site?
- Is it Storage layer replication? or Network layer replication?
