Marker messages are an idea first introduced by Chandy & Lamport almost thirty years ago in a method called the Snapshot Marker Model. Kafka’s transactions are an adaptation of this idea, albeit with a subtly different goal.

WebThe Chandy-Lamport Algorithm. Chandy-Lamport算法基于如下前提:在每对进程pi、pj之间都存在两条单向的链路cij和cji,即对于pi来讲,cij是出边,cji是入边。链路的网络可靠,缓存无限大,并且先进先出,即链路上的消息会不重不漏地按序到达。 算法要达到如下的终极 … The Chandy–Lamport algorithm is a snapshot algorithm that is used in distributed systems for recording a consistent global state of an asynchronous system. It was developed by and named after Leslie Lamport and K. Mani Chandy. See more According to Leslie Lamport's website, “The distributed snapshot algorithm described here came about when I visited Chandy, who was then at the University of Texas in Austin. He posed the problem to me over dinner, but … See more The assumptions of the algorithm are as follows: • There are no failures and all messages arrive intact and … See more The Chandy–Lamport algorithm works like this: 1.
