Gossip算法因为Cassandra而名声大噪,Gossip看似简单,但要真正弄清楚其本质远没看起来那么容易.为了寻求Gossip的本质,下面的内容主要参考Gossip的原始论文:<<Efficient Reconciliation and Flow Control for Anti-Entropy Protocols>>. 1. Gossip背景 Gossip算法如其名,灵感来自办公室八卦,只要一个人八卦一下,在有限的时间内所有的人都会知道该八卦的信息,这种方式也与病毒传播类似…

Amazon's Dynamo [9] and Facebook's Cassandra [13], relax the consistency model,and offer only eventual consistency. Others such as HBase [1] and BigTable [4] offer strong consistency only for operations touching a single partition, but not across the…
