stuffed carp

some way (lure by the fish). Well, there are types of fish, there are silver carp, Crucian carp, Octopus (Cutlass also ran to the lake, is it fresh water octopus?) Oh, it is so nonsense, do not seriously, fishing people (variables) do not have this type, he caught different types of fish. That's a bad metaphor. Make up your understanding. Reader have a good analogy, don't forget to share. Can the same va

Introduction: Consistent hashing algorithm a distributed hash (DHT) implementation algorithm, proposed by MIT in 1997, aims to solve the hot spot problem in the Internet, the original intention and carp very similar. Consistent hashing fixes the problem with the simple hashing algorithm used by Carp, which allows distributed hashing (DHT) to be truly applied in peer-to-peer environments. Scenario Introduct

Article Description: The reason we design the product is actually similar to cooking, first of all, different products to use different heat, and secondly, there is no doubt, the purpose is to do the best to eat this dish, the purpose of designing products is service products, using the design language to visualize products, so a good product design, Its design is not necessarily the most brilliant dazzling, but it must be the most suitable for this Design to pay attention to the h

Brief introduction The consistent hashing algorithm was presented by MIT in 1997 (see expanded reading [1]), designed to address hot spot problems in the Internet, with a similar intent to carp. Consistent hashing fixes the problem with the simple hashing algorithm used by carp, enabling DHT to be truly applied in peer-to-peer environments. English explanation Consistent hashing is a scheme so provides h

Java Consistent Hash algorithm learning notes (sample code), consistenthash This article focuses on the ConsistentHashing algorithm code.Consistent Hash The consistent hash algorithm was proposed by the Massachusetts Institute of Technology (see 0) in 1997. It was designed to solve the Hot pot problem on the Internet. Its original intention was similar to CARP. Consistent hash corrected the problems caused by the simple hash algorithm used by

Use ucarp for virtual IP failoverI. Overview1. UCARP OverviewUCARP allows multiple hosts to share a virtual IP address to provide automatic fault recovery. When a host goes down, other hosts automatically take over the service. UCARP is the CARP protocol (general address redundancy protocol, first implemented on OpenBSD) linux implementation version, but also can be transplanted to multiple other unix platforms, UCARP Official Website: http://www.ucar

At noon yesterday, I helped the carp to transfer database servers to a large group buying website. This article was supposed to be summarized after the transfer was completed yesterday. However, due to some reasons, I did not write it out in time. Now I want to make it up.First, the environment is like this. in mysql 5.0, The centos system of the old database server has no web, no ftp, and the new database server mysql5.1 centos nginx.The first idea o

I. Background of the problem When you use distributed data storage, you often encounter the need to add new nodes to meet the rapidly growing business needs. However, when a new node is added, it can be catastrophic for some systems if poorly handled results in all data re-sharding .Is there a viable way to migrate only the nodes associated with the data when it is re-fragmented, rather than migrating the entire data? Of course, in this case we can use a consistent hash to deal with.Second, the

dependent on abstraction;(2) to program for the interface, do not program for implementation.If the principle of opening is the goal, reliance on the reversal principle is the means to reach the "open and close" principle. If you want to achieve the best "open and close" principle, we should try to comply with the principle of dependency reversal. It can be said that reliance on the reverse principle is the "abstraction" of the best specification!! I personally feel that reliance on the reversa

The consistent hashing algorithm was proposed in 1997 by the MIT Karger and others in the solution of the distributed cache, designed to address hot spot issues in the Internet, with the original intent and carp very similar. The consistent hash corrects the problem caused by the simple hashing algorithm used by carp, so that DHT can actually be applied in the peer-to-peer environment.But now the consistent

is obtained. Many of its theories and models are based on the constraints of operational research and other related disciplines, such as linear programming, restraint theory and artificial intelligence. The main algorithms used are optimization algorithm, precise algorithm and heuristic algorithm. It can pull all the material from the terminal of the supply chain according to the order request (the guest's order), instead of just the demand list as in Mrp/erp.For example, a regular guest a firs

Today, the company organized a small discussion about the OO principles and models :) Compared with the previous Ajax explanation, this time I relaxed a lot ,! Good thing!

the client program should not be forced to rely on methods that they do not need to use. Its English abbreviation is ISP, English full name is interface segregation Principle. in fact, the interface separation principle means: an interface does not need to provide too much behavior, an interface should only provide an external function, should not be all operations are encapsulated in an interface. 6.

. For example, if you have adjusted the kernel parameters, you must run it again. /configure to make the new settings take effect. You need to re-run the configure script before using the make command to re-compile the script. There are two methods: first, run the following command: config. status -- recheck; the second is to use the command touch config. status, which updates the timestamp of the file. Note: If you want to add or delete the./configure option, you must re-enter the complete comm
