Cassandra and HBase are the representatives of many open source projects based on bigtable technology that are implementing high scalability, flexibility, distributed, and wide-column data storage in different ways. In this new area of big data [note], the BigTable database technology is well worth our attention because it was invented by Google, and Google is a well-established company that specializes in managing massive amounts of data. If you know this very well, your family is familiar with the two of Cassandra and HBase.

In the new field of Big data, BigTable database technology is well worth our attention because it was invented by Google, and Google is a well-established company that specializes in managing massive amounts of data. 　　If you know this well, your family is familiar with the two Apache database projects of Cassandra and HBase. Google first bigtable in a 2006 study. Interestingly, the report did not use BigTable as a database technology, but ...

This year, big data has become a topic in many companies. While there is no standard definition to explain what "big Data" is, Hadoop has become the de facto standard for dealing with large data. Almost all large software providers, including IBM, Oracle, SAP, and even Microsoft, use Hadoop. However, when you have decided to use Hadoop to handle large data, the first problem is how to start and what product to choose. You have a variety of options to install a version of Hadoop and achieve large data processing ...

With the proliferation of data volume, Mysql+memcache has not met the needs of large-scale Internet applications, many organizations have chosen Redis as its architectural complement, however, redis the use of the threshold is not low, such as not supporting SQL, here for everyone to share the Redis use of the full raiders. Redis, one of the most closely watched NoSQL databases, has been used by many well-known internet companies, such as Sina Weibo, Pinterest and Viacom. However, being born with no support for SQL makes him look difficult ...

Most of the domestic discussion of artificial intelligence is fragmentation of fragmentation, it is difficult to understand the development of artificial intelligence and technical system, it is very difficult to have practical reference significance. Deloitte DUP recently released a report detailing the history, core technologies and applications of artificial intelligence, especially the important cognitive techniques. This report will help us to learn more about artificial intelligence and cognitive technology, and help companies in various industries consider the real value of AI applications. This report is translated by the heart of the machine, welcome to the micro-signal: The Heart of the Machine (Id:almo ...)

We believe that the goal-oriented design method consists of 4 p, i.e. process, pattern, principles, practices (processes, patterns, principles, practices), and I will discuss the first 3 p. Interaction design is generally a difficult and messy task, and interaction designers are often asked to imagine and define in a tight schedule a possible use of the latest technology, and no one has seen, we must have a deep understanding of the complex areas of products, must balance the competitive priorities, Must understand the constraints of the technology used and the machine ...

After the release of IPhone5S and 5c, the blame for Apple's lack of innovation has been overwhelming, and every generation of iphone iPhone4 after that has been hard to escape. The Note3 that Apple's rival Samsung put out a week ago is even less of a comment. Samsung's iterations were equally palatable (if not more distasteful) after the 2011 launch of the Giant-screen stylus note.
