data, but these analyses and studies are based on the hardware architecture of the 70 's and 80 's. Now the hardware architecture, including the network architecture, and the 70 's 80 's the difference has been very large.For example, the 80 's can not imagine the PC has 2T of hard disk, even in the late 90, such a large storage system must be on the disk matrix, now a single disk drive can be solved.However, the mechanical component of the hard disk

Big data has become almost the latest trend common in all business sectors, but what is big data? is a gimmick, a bubble, or really as important as rumors. In fact, big data is a very simple term-as it says, it is a very large

with shuffle concatenation), with this model, can already handle a large part of the big data domain problem. What is a map what is reduce? Consider if you want to count a huge text file stored in a similar hdfs, you want to know how often each word appears in this text. You have launched a MapReduce program. Map stage, hundreds of machines simultaneously read the various parts of the file, respectively,

In the era of big data, the data is now a hot word, about having big data, how to play the value of big data, and talking about, and I think, it seems that this is a bit wrong cause and

may need to insert code. At this point, you need to optimize the INSERT statement. This time you can use the Insert delayed statement, which is when you make an INSERT request, the Department immediately inserted into the database and placed in the cache, waiting for the time to mature before inserting.I want to add ... MySQL Big Data processing First, overview sub-table is a relatively popular concept,

problem tangled for a long time (MySQL data old cause program memory bloat, parallel 2 direct system is down), also went to see a lot of source code only to find the miracle is here, finally through the MySQL document confirmation, and then tested, parallel multiple, and the amount of data is more than 500W, does not cause memory bloat, the GC is all right, and the problem is finally over.After reading the

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:

About nine types of technology and their fields. Then, since there is a meal, there must be cooking. So the big data technology structure selection, must have at least three kinds of components (source, calculation, storage)The simplest data processing architecture:The least unit of data processing scheme, of
