I. Overview of CAP theoryA distributed system can meet only two of the three items of consistency (consistency), availability (availability), and partition fault tolerance (Partition tolerance) at the same time.ii. definition of Cap1, consistency consistencyConsistency means "all nodes see the same data at the same time", that is, when the update operation succeeds and returns to the client, all nodes are fully consistent at the same date.For consiste

properties of acid things. But because the execution of each sub-thing is distributed in the distributed transaction, it is very complicated to implement a distributed thing processing system which can guarantee the acid characteristic.Cap theoryA classic theory of distributed systems. The CAP theory tells us that a distributed system cannot satisfy both consistency (c:consistency), availability (a:availability), and partition fault tolerance (p:part

to set the drop cap, follow these steps: Step one: First have to download a or money to install the 2013 version of Word, and then installed on the computer, these cumbersome steps here to simplify it, the installation process I do not say, anyway, first of all have to word2013 this software tool. Step Two: Then open the word2013, select the word3013, and then open it, if it is an existing file, then directly to the open Word to open you

Do a more in-depth study here.First of all, the CAP, the comparative image explanation is used to control the last bit of graphics that our brushes leave when they leave the artboard, such as rectangle

the steps for setting the drop cap in word2013 are as follows: Step one: The left mouse button double click on the computer Desktop Word2013 program icon, open it to run. In the Open Word2013 program window, click "Open Other Document" To open the Word file in the path where the file is stored. As shown in the picture; Step two: In the Open Word document window, open the Insert menu tab, and then click the Text option, select the drop

Cap theory has been used by many people as a gold law for distributed system design, but there are a lot of misconceptions about the three attributes of cap, so what is cap theory? Cap was originally a conjecture, when Daniel Brewer, in the 2000 PODC Congress, argued that when designing a massively scalable network ser

In a lot of word files or books and newspapers, and so on, like to use the first word of the sinking effect to add aesthetic effect to the text file, but a lot of friends, saw only, but did not set their own. Today, we seem to have a look at the drop cap settings in Word. Word Word2003 How to set a drop cap First of all, the selection of the paragraph you want to set the first word sinking, then c

ObjectiveI detail the isolation level of database transactions in two articles, the isolation level for database transactions and transactions and the re-discussion of database transaction isolation levels. This article will start with a distributed transaction, as well as the cap theory and base theory.Distributed transactionsWith the development of distributed computing, transactions have been widely used in the field of distributed computing. In a

overhead and availability are not good (see the CAP Section ), it brings about more problems such as conflicts and deadlocks. It is worth mentioning that the Lazy + Primary/Copy Replication protocol is very practical in the actual production environment, and MySQL replication actually belongs to this type. CAP At the 2000 PODC (Principles of Distributed Computing) Conference, Brewer proposed the famous

How to set a drop cap effect in a Word document The use of a drop cap is very wide, and you may often see the drop-cap effect in newspapers, books, and magazines. Today, let's make a small compilation of office assistants about how to set the drop-cap effect in a Word document. Word2003 How to set a drop

stand-alone database.2 Select AP, discard consistency, pursue partition tolerance and availability. This is a design-time choice for many distributed systems, such as many nosql systems.3 Choose CP, abandon usability, pursue consistency and partition tolerance. The availability of this option is low, and the problem of the network is directly unavailable to the entire system.As can be seen from the above analysis, in distributed systems, we generally choose to enhance availability and partition

Position the cursor before the text at the beginning of the paragraph, and then select Drop Cap under the Format menu The "Drop Cap" dialog box is popped up, listing 3 settings, the first is the default, the second is nested in the text paragraph, and the third is the character in the paragraph. After selecting

The cloud computing platform is a very huge distributed system that needs to process massive requests. Therefore, any small probability event must occur on this platform. DBMS emphasizes acid: atomicity, consistency, isolation, and durability ). The consistency emphasizes that the database is in the consistent state when the transaction defined by the programmer is completed. For example, for transfer, the transaction must be completed as much as a is and B is much more. For many Internet applic

obviously loses some performance.Cap theoryCap theory in Distributed systems is in full swing, everyone is saying. Do you really understand that?Let's re-comb it.The key definitions must not be less: C---consistency consistency A---availability of availability P---Partition tolerance zoning tolerance This theorem originates from the computer scientist Eric Brour of the University of California (University of California, Berkeley) in the 2000 Distributed Computing Principle

When it comes to distribution, it's important to understand the cap principle, so what is the cap principle? What the 1.CAP principle is.C (consistency) Strong consistency: All data in the distributed system is backed up, at the same time whether the same value. (equivalent to all nodes accessing the same copy of the latest data)A (availablity) Availability: Afte

is excellent, single node can handle more than 100,000 reads and writes per second;3. Low cost: This is the common feature of most distributed databases, because it is mainly open source software, there is no expensive license cost;But his flaws, the NoSQL database still has a lot of shortcomings, the common main has the following these several:1. Does not provide support for SQL: If the industry standard such as SQL is not supported, the user will have some learning and application migration c
