Preface
A few weeks ago, when I first heard about the first two things about Hadoop and MapReduce, I was slightly excited to think they were mysterious, and the mysteries often brought interest to me, and after reading about their articles or papers, I felt that Hadoop was a fun and challenging technology. , and it also involved a topic I was more interested in: massive data processing.
As a result, in the recent idle time, they are looking at "Had

In the actual work environment, many people will encounter massive data this complex and arduous problem, its main difficulties are as follows:
One, the amount of data is too large, the data in any situation may exist.
If you say there are 10 of data, it's not big enough to check each one, artificial treatment, if there are hundreds o
1th Chapter Introduction
With the wide popularization of Internet application, the storage and access of massive data has become the bottleneck of system design. For a large Internet application, billions of PV per day is undoubtedly a considerable load on the database. It poses a great problem for the stability and extensibility of the system. Through data segmentation to improve the performance of the site, the horizontal expansion of the data laye

Xsolla had a pleasant conversation with Chinese publishers and developers at the gamescom2014 game show in Germany. We have the opportunity to chat with companies from the region looking for new opportunities and markets in Western countries. Among them, the conversation with Elvina Cui from Oasis Games was impressive, discussing the localization of games and the particularity of the game market in non-Engl
In fact, any simple problem, as long as the scale is large, will become a problem, just as China has a large population and many minor problems will become a major problem. However, the method to deal with such massive data is nothing more than divide governance and "Sea of people" tactics. The premise for the use of human-sea tactics is that the problem can be divided to support such human-sea tactics, the means is nothing more than cutting (vertical

Mass data is a reality in business today
With the improvement of information level, the data has gone beyond its original category, it contains various kinds of data information such as business Operation data, report statistic data, Office document, email, hypertext, form, report and picture, audio and video etc. People use massive amounts of data to describe huge, unprecedented, a
to advise. Thank you. What is mass data processing?
The so-called mass data processing, is simply based on the mass of storage, processing, operation. What is massive is that the amount of data is too large, so it is either impossible to quickly resolve in a short time, or the data is too large, resulting in the inability to load memory at once.
What about the solution? For time, we can use a clever algorithm with the appropriate data structure, suc
The following method is a general summary of the massive data processing methods. Of course, these methods may not completely cover all the problems, however, such methods can basically deal with the vast majority of problems encountered. The following questions are basically from the company's interview test questions. The method is not necessarily the best. If you have a better solution, please discuss them with me.1.

There are two types of repeated data: one is a completely repeated record, that is, the values of all fields are the same; the other is a record with some field values repeated.
