Snapshot Algorithm 分布式快照算法是拿来干嘛的? 在缺乏全局时钟或者全局时钟不可靠的分布式系统确定全局状态 A snapshot algorithm is used to create a consistent snapshot of the global state of a distributed system. Due to the lack of globally sh
(理解这段话是很重要的,这正是Logical Clock的精髓所在。) 可以这么理解,Logical Clock解决的问题是找到一种方法,给分布式系统中所有时间定一个序,这个序能够正确地排列出具有因果关系的事件(注意,是不能保证并发事件的真实顺序的),使得分布式系统在逻辑上不会发生因果倒置的错误。 那么如何利用Happend-before关系来定...
确实,Lamport也承认这一点,他在论文最后也说了: The total ordering defined by the algorithm is somewhat arbitrary. It can produce anomalous behavior if it disagrees with the ordering perceived by the system’s users. 可是至少这种方法给出了一个定义分布式系统中事件顺序的方法,他确保的是全部因果关系的...

While I was running simulations to gather data for a paper on that algorithm, the latest issue of CACM arrived with a paper by Bell and Charles Kaman titled The Linear Quotient Hash Code. I had devised three variants of the algorithm not contained in their article. So, I wrote a paper ...
Lamport then describes a simple algorithm for building causally consistent logical clocks. The key guarantee is that it produces a timestampC(e)for every eventethat has the property that ife > e', thenC(e) > C(e'). To motivate the utility of this clock, he then shows an algorithm for...
