如何理解minority side of the partition

[村夫大胡子]

redis cluster文档内容
1. Writes targeting the minority side of a partition have a larger window in which to get lost. For example, Redis Cluster loses a non-trivial number of writes on partitions where there is a minority of masters and at least one or more clients, since all the writes sent to the masters may potentially get lost if the masters are failed over in the majority side.

2. Redis Cluster is not available in the minority side of the partition. In the majority side of the partition assuming that there are at least the majority of masters and a slave for every unreachable master, the cluster becomes available again after NODE_TIMEOUT time plus a few more seconds required for a slave to get elected and failover its master (failovers are usually executed in a matter of 1 or 2 seconds).

在看redis cluster文档的时候, 因本人愚钝, 无法理解minority side和majority side, 以及为什么分区少数的一侧会丢失更多写数据. 所以来这里问问大家, 最好是可以说个易懂的例子.
