- sample
- reddis style master-slaves architecture
- used for smart home or other systems that rely on MQTT being up full time.
- Basically each PI would be a MQTT broker that would all relay to a Master Broker. If the master falls over, the remaining "slave" brokers vote on who will be the new "master".
- Once the old master gets back online it becomes a slave to the new master.
- master - slave
- Inspiration: recent failure of many smart home devices after the East Coast AWS server crashed.
