Differences between clusters and Distributed Systems The difference between clusters and distributed systems. Cluster: A cluster is a group of service entities that work collaboratively to provide a service platform that is more scalable and available than a single service entity. In the client's view, a cluster is lik

Introduction"Theory advanced in Distributed Systems-Paxos" introduces the consistency protocol Paxos, today we will learn two other common consistency protocols--raft and Zab. By comparing with Paxos, we understand the core ideas of raft and Zab and deepen the understanding of conformance agreements.RaftPaxos is biased toward theory, which mentions less about how to apply to engineering practice. The diffic

In the first part of "Designing Data-intensive Applications" (see above), the basic theory and knowledge of the data system are introduced, all based on single node. In the second part of the Ddia (distributed data), the field of view is extended to the distributed Data system. There are three main reasons for the distribution of data: Scalability Fault Tolerance/high Availability Reduce Latenc

The distributed command mode is a recommended mode for architecture design. Compared with the design of common applications, it should be considered more in the interconnected system. The goal of this model is to have the same design for both an independent system and an interconnected system. This mode allows developers to focus on designing a common application that follows the command mode without considering that the application will be connected

IntroductionIn distributed systems, time is a huge problem, because there will be their own physical time on different computers, and how to achieve the consistency of state affairs is often difficult. The lack of a global physical time makes it difficult to find out how the state of execution of a distributed program is.clock, event, process state, and time sync

all levels of the distributed system, single database system, and even memory variables.Scenario 1: high read response speed requirements There is a type of system that is frequently updated and requires high read response speeds, such as stock trading systems. Under the lock mechanism, write will block read, so when there is a write operation, the response speed of the read operation will be affected; whi

protocol, which is hosted on GitHub and is currently the latest version of 0.6.1. Last year 10, Li Haoyuan in an interview with Infoq, said:In the long run, they will treat Tachyon like Apache Mesos and Apache Spark, Tachyon will also enter the Apache Software Foundation, where more developers are welcome to join.Tachyon won a $7.5 million a-round investment in Silicon Valley's VC a16z, the Wall Street Journal told the News recently. Amplab's project also includes an open-source cluster computi

This past weekend I read Joe Armstrong's paper on the history of Erlang. Now, HOPL papers in general is like Candy for me, and this one does not disappoint. There ' s more in this paper that I can cover in one post, so today I ' m going to concentrate on one particular feature of Er Lang highlighted by Armstrong.Although Erlang is designed to encourage/facilitate a massively parallel programming style, it error handling may be even More noteworthy. Like everything else in Erlang, it error handli

callback: the server records which clients read the data, when the server changes the data to notify the logged clients first, the last read data has been invalidated. These two methods have some drawbacks, reference: Lease mechanism IntroductionTherefore, a lease mechanism can be introduced. During the lease term, you can ensure that the data cached by the client is up-to-date. When the lease expires, the client needs to re-ask the server for data and renew it.Definition of Lease: A lease is a

Introduction to Distributed File Systems 1. The origin of the story Or many years ago, I had a small system, a small system related to payment. Because it is a small system, everything is so simple. An application server and a database server. Files and images are stored on the application server. Everything is so plain that everything is taken for granted. Suddenly one day, payment became a fashionable top

Distributed File System1. the increasing volume of data, which cannot be stored in a range of operating system jurisdictions, is allocated to more operating system-managed disks, but is not easily managed and maintained, so a system is urgently needed to manage the files on multiple machines, resulting in a distributed file system.2. It is a file system that allows files to be shared across multiple hosts o
