big data implementation examples

This article mainly describes in detail the information about how to implement the big turntable of 9ugu Based on javascript. If you are interested, please refer to the examples in this article to share with you how js achieves the big turntable of 9ugu based lucky draw, for your reference, the specific content is as follows:

packaging, tomcat deployment, inconvenient development and testing personnel, unfriendly to newcomers Poor performance and difficulty in scale-out Third, the application of containerizedTo solve the above problem, we try to make sure that we need to move to the big data platform first. At the same time, we did some containerized work. The purpose of these tasks is to facilitate deployment and migr

unexpected unrecoverable failure. The MapReduce jobs are executed sequentially and finalized. Both are distributed and fault-tolerant If the nimbus/supervisor freezes, restarting makes it continue from where it stopped, so nothing is affected. If Jobtracker crashes, all running jobs will be lost. Examples of using Apache stormApache Storm is well-known for real-time

The fine operation of Shopping center is imperativeWhile online retailing has had a big impact on offline retailing, in the real ratio of retail sales, offline retail accounted for up to 90%, while online retailing accounted for only 10%. Looking to the future, offline retailing is still an important part of retail, because each of us has a physical body, physical convenience and physical experience, both of which support the long-term development of

, RESULTSET.CONCUR_READ_ONLY);To set the cursor so that the cursor does not cache the data directly into local memory, and then sets Statement.setfetchsize (200), setting the size of each traversal of the cursor; OK, I used it, Oracle used and useless no difference, Because the Oracle JDBC API by default is not to cache the data into Java memory, and MySQL is not set at all, I said a bunch of crap, hehe, I

Using. Net for sorting and paging to solve big data problems I. Overview: The DataGrid is often used in Web applications. However, the DataGrid Control performs sorting by arch. The paging function is unrealistic for tables with a large number of records, for example, if a table contains 0.2 million records, all records must be retrieved based on the order of the DataGrid and the principle of paging,

Preface In order to adapt to the requirements of big data scenarios, new architectures such as Hadoop and nosql that are completely different from traditional enterprise platforms are rapidly emerging. The fundamental revolution of the underlying technology will inevitably affect the superstructure:

algorithm, every step, the surfer may not want to see the current page, do not see the current page will not click on the connection above, and quietly in the address bar to enter another address, and in the address bar input and jump to each page the probability is 1/n. Assuming that the Internet users each step to view the current page probability is a, then he jumps from the browser address bar probability is (1-a), so the original iteration formula into:Now let's calculate the probability d

introduce several common join algorithms supported by Sparksql and their applicable scenarios.join common classification and basic implementation mechanismThe current SPARKSQL supports three join algorithms: Shuffle hash join, broadcast hash join, and sort merge join. In the final analysis, both of them belong to the hash join, but before the hash join need to first shuffle or broadcast. In fact, the hash join algorithm from the traditional database,

The evolution of the Apache Kylin Big data analytics PlatformExt.: http://mt.sohu.com/20160628/n456602429.shtmlI am Li Yang from Kyligence, co-founder and CTO of Shanghai Kyligence. Today I am mainly here to share with you the new features and architecture changes of Apache Kylin 1.5.　　　　What is Apache Kylin?　　Kylin is an open source project developed in the last two years and is not very well known abroad,
