DB replication can be a bastard. Think monotonically increasing ID style keys. If both nodes have different data records for the same primary key entry for ID 12345 that are then linked into other data records, then you have to untangle the mess. In dual node systems you can do odds & evens, but in multi node clusters it gets a lot uglier

Not a DBA, but I pretend sometimes when the real DBAs are away.
