Well, they didn’t have an algorithm, just a bunch of code. Very few programmers think in terms of algorithms. When trying to write a concurrent system, if you just code it without having algorithms, there’s no
I consider the algorithm to be a straightforward application of the basic ideas from Time, Clocks and the Ordering of Events in a Distributed System. 正如Lamport 所述,算法的思想非常的 straightforward,在描述算法之前需要先介绍一下 Global Snapshot。
What was wrong with their original algorithm? Well, they didn’t have an algorithm, just a bunch of code. Very few programmers think in terms of algorithms. When trying to write a concurrent system, if you just code it without having algorithms, there’s no way that your program is not ...
As an illustration, I used the simplest example of a distributed system I could think of--a distributed mutual exclusion algorithm. 状态机贯穿了 Lamport 的大量研究。例如,Paxos的推导基于状态机、不变式和强归纳法;Lamport 近年来大力推广的形式化验证( TLA+)是基于状态机模型;"Distributed Snapshot"一文...

Spark的 Structured Streaming 的 Continuous Processing Mode 的容错处理使用了分布式快照(Distributed Snapshot)算法 Chandy-Lamport 算法,那么分布式快照算法可以用来解决什么问题呢? Asnapshot algorithmis used to create a consistent snapshot of the global state of a distributed system. Due to the lack of glo...
morning, in the shower, I came up with the solution. When I arrived at Chandy's office, he was waiting for me with the same solution. I consider the algorithm to be a straightforward application of the basic ideas from Time, Clocks and the Ordering of Events in a Distributed System. ...
Asnapshot algorithmis used to create a consistent snapshot of the global state of adistributed system. Due to the lack of globally shared memory and a global clock, this isn't trivially possible. 简单来说就是用来在缺乏类似全局时钟或者全局时钟不可靠的分布式系统中来确定一种全局状态。
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 sha... ...
《Time,Clocks and the Ordering of Events in a Distributed System》 绕不开的Leslie Lamport 数学【数学是皇帝,物理是皇后】。【宗教:万佛朝宗】 归纳,类比,演绎,反证。 第一性原理。数学,物理,宗教。。。 etcd is written in Go and uses the Raft consensus algorithm to manage a highly-available replic...
