What if the number of boxes are even? Or do you get around this by not deploying an uneven number of boxes?

What if the number of boxes are even?
Or do you get around this by not deploying an uneven number of boxes?
- gregmac 8y agoThis makes me wonder also what happens with multiple partitions, for example: 5 into 2, 2, and 1 7 into 3, 2, and 2
- traviscj 8y agoNo majorities, I guess?
- voidmain 8y agoThe number of coordinators is separate from the number of boxes. You don't have to have a coordinator on every box. I think you can set the number of coordinators to be even, but you never should - the fault tolerance will be strictly better if you decrease it by one.
- maccam94 8y agoThe majority is always N/2 + 1, where N is the number of members. A 6 member is less fault-tolerant than a 5 member cluster (quorum is 4 nodes instead of 3, and it still only allows for 2 nodes to fail).
