set the minimum cluster size to 49,999? ;-P
it sounds pretty likely to me. I mean, just with that many cluster members, there’d have to some likelihood that the communication overhead trying to discover the seed nodes and elect a leader and what not would result in at least some of these nodes being isolated from the others, even if only for a brief moment.
but I’m just speculating. maybe the lightbend guys know of instances where customers did exactly this and didn’t even need their split-brain resolver!?
