Autonomous IoT data is exactly opposite of needing global consistency. I can't say what it is, but this system isn't even hooked up to the internet. It needs immediate local and autonomous decisions made, part of why they chose gun.
@jimktrains2 it is nearly impossible to lose data with gun because of its master-master replication even into the edge/peers. It is about as fault tolerant as you can get (check out the links to the tests I mention in the other comments).
I understand now how it might have sounded confusing, sorry about that! Mission critical systems often require HA, not master-slave. Master-slave is very important in other use cases.
