You may want to configure the replication backlog size (see the next # sections of this file) with a sensible value depending on your needs. # 3) Replication is automatic and does not need user intervention. Af

Redis 集群通过分区(partition)来提供一定程度的可用性(availability): 即使集群中有一部分节点失效或者无法进行通讯, 集群也可以继续处理命令请求。 Redis 集群提供了以下两个好处: 将数据自动切分(split)到多个节点的能力。 当集群中的一部分节点失效或者无法进行通讯时, 仍然可以继续处理命令请求的能力。

Partition tolerance(分区容错性):一台服务器放在中国,另一台服务器放在美国,这就是两个区,它们之间可能无法通信。 CAP理论的核心是:一个分布式系统不可能同时很好的满足一致性,可用性和分区容错性这三个需求,最多只能同时较好的满足两个。 因此,根据CAP原理将NoSQL数据库分成了满足CA原则、满足CP原则和满足AP原则...
