get more votes in Primary's primary election, Arbiter does not need specialized hardware to support it. The following is the replica set schema for adding arbiter:Note: A arbiter will always be a arbiter, meaning that in a replica set schema an arbitrator will always be an arbitrator, and a primary can become a secondary, A secondary can also be a primary in a re-election. However, the arbitrator cannot change in the architecture regardless of the oc

1. Overview Dr. Roy Fielding (see Personal homepage) is the main designer of the HTTP and URI protocol issued by the IETF. HTTP and Uri are the two most important web infrastructure protocols, so Dr. Fielding is one of the founders of the Web architecture. In addition to academic excellence, Dr. Fielding has been involved in the design and development of many Open-source software. He was the developer of Libwww-perl, one of the world's earliest HTTP

Two structure differences and advantages and disadvantages of C/s and b/s, architecture I. C/S architecture 1. Concept C/S architecture is a typical two-tier architecture, the whole process is client/server, that is, the client server-side architecture, the client contains

: Interface high cohesion is internally highly dependent and isolated as much as possible. That is, the method of internal declaration of an interface is related to a sub-module, and is required by this submodule. Interface design is limited: If you fully follow the principle of interface separation, there will be a problem, that is, the design of the interface will be less and less, so that the number of interface increases, the complexity of the system increased suddenly, rather than the

search key Many applications access new data more frequently than old data, so we want the data to be roughly sorted by time, but also evenly distributed, so that we can keep the data we are reading and writing in memory and distribute the load evenly across the cluster. For example, there is an analysis program that allows users to access data over the past one months on a regular basis, and we want to keep the data as easy to use as possible, so we can shard on {month:1,user:1}, where mo

About MySQL ArchitectureThe MySQL server is comprised of the SQL layer and the storage engine layer. SQL layer functions include permission judgment, SQL parsing and query cache processing, and the storage engine layer is the completion of the underlying database data storage operations. Such as:650) this.width=650; "Src=" Http://s1.51cto.com/wyfs02/M01/8B/D4/wKioL1haPWbDb90NAAAzcpVeDV4246.png-wh_500x0-wm_3 -wmp_4-s_3519715006.png "title=" 1.png "alt=" Wkiol1hapwbdb90naaazcpvedv4246.png-wh_50 "/

purpose of the flow queue data is to determine the data in the table where the data will be keptis insert,update and delete, and each operation generates the corresponding log information. In MySQL, if theThe storage engine that holds the transaction, the amount of this log generation is doubled. And if we go through some mature third-party queue software toThe performance of this queue data processing function will be multiplied.3. Super-Large text dataFor MySQL versions prior to 5.0.3, the VA

Http://www.cnblogs.com/zhhh/archive/2011/06/10/2077519.htmlI also see someone asking about the three-tier architecture and the MVC relationship, which is a bit of a dogma. Because they all logically put the application into three blocks, rounding up a number 3, someone has to link them together.These two things I touch for several years, have a little experience, Express:Layer three is layer three, MVC is MVC, they have nothing to do with it.layer Thr

Extensibility-A new business is on the line(1) Measurement criteria: Is it possible to achieve transparency without impact on existing products when new business is added (does it need to be modified to match existing business?) ）；(2) Main means:① Event-Driven architecture: Using message Queue implementation;② Distributed services: separating business and reusable services;V. Security

Design objectives: -(Hardware failure is normal, not accidental) automatic rapid detection to deal with hardware errors -Streaming Access data (data batch processing) -Transfer calculation is more cost-effective than moving the data itself (reducing data transfer) -Simple data consistency model (one write, multiple read file access model) -Heterogeneous Platform portability HDFS Architecture Adopt Master-slaver Mode: Namenode Central Server (Master)

Analysis of Three-tier architecture, analysis of three-tier architectureThree-tier architectureLet's take a preliminary look at the three-tier architecture through several questions.1. What is a three-tier architecture?2. Application Scenario-why should we use a three-tier architecture?3. Role of layer-34. Relationship

I think the project structure based on Laravel some of the design is more practical and reference, and now some design to share to everyone, and we hope to le

With the individuation of user demand and the shortening of product life cycle, the micro-service architecture is the inevitable direction of future development of software software architecture towards flexibility, expansibility, scalability and high availability. At the same time, the popularity of container virtualization technology represented by Docker will greatly reduce the cost of implementation of

Evolutionary architecture (evolutionary architecture) and emergency design (emergent) are agile technologies that postpone important decisions to the last-minute responsibility (responsible Moment). In the first installment of this series, Neal Ford, a series author, will define the architecture and design, and then indicate some basic concepts about the entire s

Introduction to Event-driven architecture (Event-driven Architecture,eda)There are two ways to understand EDA: EDA is an architectural pattern that focuses on generation/consumption-based asynchronous communication. This is mainly compared to traditional thread-based synchronization systems. EDA is a kind of architecture mode which takes event as the

What is the architecture of a software system )? Generally, the architecture has two elements: · It is the highest level of division of a software system from the whole to the part. A system is usually composed of components, and how these components form and interact with each other is an important information about the structure of the system. Specifically, it includes
