feel very strange, perhaps at present you do not have vim to produce any favor, do not think it is a good editor, it can only be because you have not mastered the essence of vim, or you type too slow, go back to the Little Overlord learning machine to practice it-_-| | Here can also be revealed, the essence of vim is the command key combination, the operation of the whole keyboard, you can not leave the keyboard input area to complete all the operation, that can be real efficient and cool exper

1. What is ganglia
An open source cluster monitoring project; Ganglia can do system monitoring, however, currently it does not support server exception or fault alarm function.
2.Ganglia Monitoring Cluster architecture
Ganglia cluster is mainly composed of the 3 daemons, Gmond, Gmetad, Gweb, and the Gmetad process is equivalent to the master of the monitoring cluster. While multiple Gmond processes can be grouped, each

The network is the "highway" of the amount of data in the data center, and the construction of these "highways" must be planned and designed in a unified manner to give full play to the advantages of network interconnection. A network with advanced

Preface
In this section, we will continue our SQL journey. In this section, we will talk about some basic knowledge and precautions. If there are any mistakes, I hope to point out the short content, in-depth understanding.
Database architecture and objects
The database con
coexist the argument is absurd, the two architectures should be complementary, we can use together." ”
Harrison says it makes sense to choose Kimball when building a data mart because it is relatively simple to understand and provides excellent performance and quick returns. This architecture is designed to deliver data to business users as quickly as they can,
by the service layer. This is also the key to the architecture.
Data access layer and performance Layer: theoretically, the data access layer cannot reach the performance layer. In the real world, the presentation layer may directly call some methods in the data access layer. The key to doing so is not that you can "s

The data access interface defines the data access interface of logical object B.Logical object a uses the data access interface to access logical object B.

Tags: Data Exchange Platform Architecture DesignPrefaceWhen it comes to architecture design, I dare not be arrogant. We can only pay tribute to Linux in silence. Without a powerful Linux system, the architecture we designed may be several times a day. (I won't talk about windows, huh, huh)
As a data pipeline, operators have many data resources and have natural advantages, but they still face challenges in how to use their value effectively. This lecture first analyzes the advantages and disadvantages of the operator data, analyzes the application demand of the operator data in the marketing field, transl
Problem IntroductionUsing storm, you can easily build a clustered data framework and implement business logic by defining topo.But with Topo there is a disadvantage that Topo's processing power comes from the number of workers they set up at startup, and in many cases we need to be able to adjust the processing power of the cluster based on business pressure, when a single topo cannot solve the problem.In order to be able to define the processing abil

The data collected by the monitoring platform is a typical time series data over
This topic seems a bit big, the things involved seem a bit more!
With the development of the market, more and more platforms are now required to have a large amount of traffic, large data volume of efficient processing capacity but what exactly?
There are two main problems:
1, how to solve the problem of large number of visits, simple: fast, stable, safe?
2, how to solve such a large amount of traffic cause
