Are retained messages not replicated in a cluster?

[Ziris85]

Hello folks, I've been using the MQTT plugin for a while now for miscellaneous things to talk to my homeassistant setup, but have been chasing an issue down whereby tasmota devices remain unavailable after restarting homeassistant until I restart the devices as well. It seems the answer is to set some/all messages to be retained; however, upon reading the docs on the plugin, it seems to explicitly state that retained messages are NOT replicated across a cluster, thus rendering that feature useless in such a setup:

Retained messages are neither replicated to nor queried from remote cluster nodes.

I'm just wondering if that's actually true (if so, why?), or if maybe I'm just misinterpreting what it's saying? I have a three-node rmq cluster set up, but if this cannot support retained messages in a cluster, then I'll either have to tear it down to a single node/point of failure, or go back to using mosquitto or something else.

Thanks in advance!

I'm not sure how I ended up on this specific project, but I see now that this is the GH page for the actual website, rather than the server project (which is where this question would be more appropriate). I'll close this here.
