Hi, In current implementation write-behind store can lose writes even if only one nodes fails. This can be improved by adding backup queues [1], but it's not implemented yet. Of course, this will not help if you lose more nodes than number of backups you have (in this case data in memory is also lost). Only synchronous write-through can guarantee that there are no data loss.
