dwarf cap

Today, I was asked about cap, and I found https://my.oschina.net/lilw/blog/169776 this text,Here's an explanation of the CAP's text:The so-called cap theory, namely:Cosistency consistency of dataAvailability High AvailabilityTolerance to NEWOWRK partitions zoning toleranceA data storage system can not meet the above three features at the same time, only meet its two characteristics, namely: Ca,cp,ap. So to

The feature of Internet service is to face the massive user, how to provide the stable service for the massive level of the user. Here, some of these years of experience accumulation and peacetime contact some of the ideas to make a summary.I. Principles1. The CAP principle for Web servicesCap refers to three elements: consistency (consistency), availability (availability), partitioning tolerance (Partition tolerance).

Database ACID and CAP theory 1. ACID is the theoretical cornerstone of RDBMS. Atomiclty is the transaction atomicity. C is consistent and inserts A table data, will affect other (index/other tables) consistency. I isolation (ioslation) transactions are independent, closed; Isolation Strength; D persistence (Durabilty) Data persists. Corresponding to distributed databases, some services do not require all consistent transactions, and one of them can be

Recently, when tossing a middleware, we used the Cap ' n Proto A simple look, declaration names should use CamelCase and must not contain underscores # and when defining types can not be used in lowercase or down line, you need to use hump type, OK Alkai D's favorite. Have time to know protobuffer or thrift. That's all, and then some simple test code: Import Osimport Capnpthis_dir = Os.path.dirname (__file__) node = capnp.load (Os.path.join (This_dir,

In a Word document, if the article is very long, you generally choose to enlarge the first font of each paragraph so that it looks more aesthetically pleasing and can also have a prominent effect. One of the adjustment font size, this approach is not scientific, below, to teach you a quick set of methods. ① Open the Word2007, enter some text, then click on the menu bar-Insert, click on the text to sink the first word. ② Select the drop cap op

Topic content:The program reads a positive three-digit number each time, and then outputs the number in reverse order. Note that when the input number contains the end of 0 o'clock, the output should not have a leading 0. For example, enter 700 and the output should be 7.Hint: to a three-digit number x, do x%10 can get its single digit, do x/100 can get its hundred number, 10 digits through/and% two operation combination can be obtained.Input format:Your program reads a positive integer of 3 bit

Solving the puzzle: divide and conquer the minimum cut."L......R" in any of the two as S, T (may wish to set S as the point on the L position, T set to the point on the R position) for the minimum cut, two for the Loop enumeration modified MAP[I][J] that is the minimum cut value between two points.Then part of the S set, part of the T set, divide and conquer "l,l", "R,r", each time the minimum cut value is the global modification.Finally, every time you ask for violence, you don't need any optim

system either sacrifices the consistency (most of the time), or sacrifice the availability. Application Scenarios Since the CAP cannot be met at the same time, the system must be designed to weaken the support for a particular feature. weakening consistency Applications that are insensitive to result consistency can allow for a period of time after the new version is online to be successful, with no guarantee of consistency.For example, the website

Distributed system: Deployed in different nodes, through network communication to achieve collaborative work. Cap understands: C:consistency, all nodes seeing the same data at the same time; strong consistency is the same as when the client sees the nodes at any point. A:availability, reads and writes always succeed; high availability is read and write at all times. P:partition tolerance, the system continue to operate despite Arbitray message loss or

When designing and building VMware virtual platforms, it is often necessary to query the maximum value of VMware vsphere (maximums). In fact, not only VMware, the design of any IT infrastructure solution must be aware of the software/hardware limit capabilities. For VMware, this term is called the configuration maximums.I often have such a distress, as the VMware version changes, the Configuration maximum values are actually changing. For example, before v5.5, the maximum number of hosts in a cl

fraction, and calculate its decimal form. Outputs up to 200 digits after the decimal point, whether or not it can be removed.Input format:Shaped likeA/bTwo numbers, of which 10Output format:Shaped like0.xxxxxxxxxDecimal, up to 200 digits after the decimal point. The output ends with a carriage return with a newline. If A/b is a limited non-repeating decimal, then the output of all the valid bits will be able to, do not need to output the back of the 200-bit full.Input Sample:16/19Sample output:

Topic content:Each non-prime (composite) can be written as a number of primes (also known as prime numbers) in the form of multiplication, and these primes are called the composite's mass factor. For example, 6 can be decomposed into 2x3, and 24 can be decomposed into 2x2x2x3.Now, your program reads an integer in a [2,100000] range, then outputs its mass factorization, and when it reads a prime number, it outputs itself.Input format:An integer that is within [2,100000].Output format:Shaped like:

thousand part; If the hour is 0, there are no hundred parts, and if the hour is not 0 and the score is less than 10 points, 10 of the 0 bits are required, and 0 on 10 is not required if the hour is 10 and less than 0 points.Caution: Be careful with cross-day conversions.Input format:An integer that represents the time and minute of the BJT. The number of bits and 10 digits of an integer represents the minute, and the hundred and thousands denote hours. If the hour is less than 10, there is no t

Topic content:Your program reads a series of positive integer data, input 1 indicates the end of the input, and 1 is not the input data itself. The number of odd and even numbers in the data read by the program output.Input format:A series of positive integers in which the range of integers is (0,100000). If input-1 indicates the end of the input.Output format:Two integers, the first integer representing the number of odd numbers in the read data, and the second integer representing the number o
