What Is Framework In Computer

Multithreading is the problem that programmers often face in the interview, the level of mastery and understanding of multithreading concept is often used to measure a person's programming strength. Yes, ordinary multithreading is not easy, then when multithreading encounter "elephants" will produce what kind of sparks? 　　Here we share the Java thread Pool management and distributed Hadoop scheduling framework with 严澜, the Shanghai Creative Technology director. Usually the development of the thread is a thing, such as Tomcat in the servlet is the threads, no thread how we provide more ...

Usually the development of the thread is a thing, such as Tomcat is a servlet in the threads, there is no thread how do we provide multi-user access? But many developers who have just started to touch threads have suffered a lot. 　　How to do a set of simple threading Development Mode framework for everyone from the single thread development into multithreaded development, this is really a relatively difficult project. What is the specific thread? First look at what the process is, the process is a system executed a program, this program can use memory, processor, file system and other related resources ...

Translation: Esri Lucas The first paper on the Spark framework published by Matei, from the University of California, AMP Lab, is limited to my English proficiency, so there must be a lot of mistakes in translation, please find the wrong direct contact with me, thanks. (in parentheses, the italic part is my own interpretation) Summary: MapReduce and its various variants, conducted on a commercial cluster on a large scale ...

Research and realization of clustering and convex-package algorithm in MapReduce framework Chengdu University of Technology Zhaoju first, this paper makes a research on the generation and value growth of large data, and explains the necessity of improving the execution efficiency of the data mining algorithm, and introduces the technology and tools that support the large-data processing now. Then the paper studies the running mechanism of Hadoop file system, the stored procedure and the programming model of MapReduce framework, and the operation principle. Secondly, in a certain size of Hadoop cluster on the data distributed processing, so as to assess the whole cluster of sex ...

Application framework of Hadoop platform in financial banking Shijiangyan I. The current situation of financial banking industry with the development of financial banking and the improvement of the level of network communication infrastructure, the informationization of financial banking industry has become more and more popular, but with the rapid development of Internet technology and application, many new forms of payment have been emerging, 　　The amount of data in the financial banking industry is also growing rapidly, and the volume of related business data is rising sharply, and financial banking is entering a big data age. Due to the congenital insufficiency of relational database, the large amount of data will be modeled on the traditional relational database.

In the SIP project design process, for its large log in the early consideration of the use of task decomposition of multithreading mode to analyze statistics, in the previous blog mentioned that part of the design, but because the content of the statistics is still very simple, Therefore, the use of memcache as a counter combined with MySQL completed http://www.aliyun.com/zixun/aggregation/38609.html "> Access control and statistical work." But the future, for the massive day ...

1. With the rapid development of computer technology, the application of database is very extensive, in-depth to various fields, but with the resulting data security problems. The security of large amount of data in the database of various application systems, the problem of stealing and tamper-proof of sensitive data are paid more and more attention by people. The database system as the information gathers the collective, is the computer Information System core component, its security is vital, relates to the enterprise rise and fall, success or failure. Therefore, how to effectively ensure the security of the database system to achieve data confidentiality, integrity and effectiveness, has become the industry to explore ...

Remote invocation is the communication mechanism between system and process, and is the core technology of distributed system development. Remote invocation technology can form a group of computer systems into a network system, the external provision of the overall service, then this group of computer systems constitute a larger, more performance of the computer system. A general statement on the architecture design of the remote invocation service first, we need to understand the following questions: Why is a remote invocation service required in an application software service? What is the problem with the remote Invoke service that solves the software design? I have written an article on the design of distributed Web site architecture, ...
