　In the development of distributed cluster system, the thread lock is often not able to support the use of all scenarios, and a new technology scheme distributed lock must be introduced.　　thread Lock: Everyone is not unfamiliar, mainly used to give methods, code block lock. When a method or block of code uses a lock, at most one thread at the same time executes the code. When there are multiple threads acce

At present, almost a lot of large-scale Web sites and applications are distributed deployment, data consistency in distributed scenarios has always been a relatively important topic. The distributed Cap theory tells us that "none of the distributed systems can meet both consistency (consistency), availability (availabi

I. Introduction of Distributed Locks Distributed locks are mainly used to protect mutually exclusive access to shared resources across processes, across hosts and across networks in a distributed environment to ensure data consistency. Ii. Introduction of the framework Before introducing using zookeeper to implement

ClassificationThe distributed crawler consists of multiple crawlers, each of which has to perform tasks similar to a single crawler that downloads pages from the Internet and stores the pages locally on the disk, extracting URLs from them and continuing crawling along the points of those URLs. Because the parallel crawler needs to split the download task, it is possible for the crawler to send its own URL to other crawlers. These reptiles may be

First, the difficulty of the distributed systemWhat are the difficulties in distributed systems compared to single-machine systems?1. Network factorsSince services and data are distributed on different machines, each interaction needs to run across machines, which poses several problems:1. Network latency: Performance, timeoutThe same computer room network IO is

This article was translated from distributed algorithms in NoSQL DatabasesThe scalability of the system is the main reason for the development of the NoSQL movement, including distributed system coordination, failover, resource management and many other features. That makes NoSQL sound like a big basket, and everything can be plugged in. Although the NoSQL movement does not bring fundamental technological c

Today, we'll look at some distributed policies, such as replication in fault detection, which are labeled in bold and are divided into three segments: Data consistency. NoSQL needs to be weighed against the consistency, fault tolerance and performance, low latency, and high availability of distributed systems, in general, data consistency is a mandatory option, so this section is primarily about data
