background For the SQL query service of a data platform, Impala provides a query engine that is superior to a batch of sql-on-mr/spark performance, such as Hive/spark SQL, and benefits from Impala can directly share hive Metastore, can provide users with " A set of data, multiple engine "services, currently we plan to integrate Hive/spark/impala these SQL engines in the data platform. As we all know, hive is better than both in stability and maturity, whether it is spark or impala in the proces

Introduced Agent, as the name implies is to help others to do things, gof the agent mode is defined as follows: Agent mode (proxy), which provides a proxy for other objects to control access to this object. The proxy mode makes the proxy object control the reference to the specific object. Proxies can be almost any object: files, resources, objects in memory,

The latest browsers fully support HTML5. When referencing the foreign resource, verify the Cors in addition to JavaScript and CSS. The browser confirms that the Access-control-allow-methods header of the server response does contain the method of the AJAX request that will be sent before continuing to send Ajax,

The JDK implementation dynamic Proxy needs to implement the class through the interface to define the business method, for the class without the interface, how to implement dynamic proxy, this needs cglib. Cglib uses a very low-level bytecode technology, which is based on bytecode technology for a class to create subclasses, and in subclasses using method interception techniques to intercept all the calls of the parent class method, the trend of weaving into the crosscutting logic. Both the JDK

Agent job 1. about SQL server agent use SQL server to store job information. A job contains one or more job steps, each of which has its own job. SQL server the agent can run jobs as scheduled or run jobs in response to specific events, you can also run the job as needed. By default, SQL server the

The new company monitoring with the Zabbix, which used to Zabbix-proxy, originally did not try to get, now first installed to see in order to follow up the use of inspection.Zabbix-proxy is a monitoring proxy server, which collects the monitored data, stores it in the buffer, the time can be set by the configuration file, and then transferred to Zabbix_server; the monitoring agent needs a separate database .Zabbix-proxy solved the problem:1, reduce th

Oracle intelligent agent executable encounters a problem Recently, I just installed Oracle 9i on the system and found that the computer name was not changed after the installation. After I changed the name, every time I started the system, the system prompts "Oracle intelligent agent executable encountered a problem, you need to disable "to send error reports, which is too annoying. Finally, I found a solu

Proxy design mode Proxy design mode, also known as "delegation", as the name implies is entrusted to others to do thingsIn the proxy mode, one party is called the principal and the other party is called the agent.The principal and the agent are linked together through the agreement.When the client wants to get the agent to do something, it only needs to send a proxy message to the agent650) this.width=

Static proxy1. Role Analysis of static agents (UML drawing recommends using STARUML software)Abstract roles---generally implemented using interfaces or abstract classes.It's really the role---being represented.Proxy role---Proxy real role-the agent is usually a subordinate operation after the role.The customer-------Use the proxy role for some action.2. Implementation of the code (landlord-intermediary-customer)rent.java--Abstract RolesPackage Cn.sxt.

1, the purpose of dynamic agentsThe dynamic proxy is used for separating the code, separating the common code from the various business modules, eliminating the need to implement it in every business module, which reduces the development workload and facilitates maintenance;eg: "Eat", "talk" both businesses need to use the "mouth" "Shut up" the two lines of code, but after the mouth and shut up before the things are not the same, so that the business module and the general module (that is, mouth

One or two kinds of proxy modes: static agent and dynamic agentAgent mode, basically have subject role, realsubject role, proxy Role. Where: the subject role is responsible for defining the interface that the Realsubject and proxy roles should implement, and the Realsubject role is used to actually complete the business services function, and the proxy role is responsible for invoking the request of itself, calling Realsubject The corresponding reques

Implementation of dynamic AgentMode used: Proxy mode.The role of proxy mode is to provide a proxy for other objects to control access to this object. Like a rental intermediary.Two kinds of dynamic agents:(1)JDK dynamic Agent , JDK Dynamic agent is implemented by the reflection mechanism inside Java, the target class is based on the Unified Interface (Invocationhandler)(2)cglib dynamic

Urllib.request.urlopen (URL) is often used in crawlers to open web pages, such as getting page status return valuesThe problem is that Urlopen sends the version of Python urllib on the user-agent that is sent on the GET request, looking at the following clutchGet/xxx.do?p=xxxxxxxx http/1.1accept-encoding:identityhost:xxx.xxx.comconnection:closeuser-agent:python-urllib/ 3.4　　Take a look at the sourceThe normal request should be the browser's user-agent

proxy modeThe above code is just an example of a UML diagram and does not fully describe the proxy pattern. Agent mode is to emphasize a proxy, the above example is in fact directly with the realsubject can be, there is no need to use proxy. In addition the proxy and the Proxied object do not require a common parent class/interface. There are several common scenarios for proxy mode:-Remote Proxy: If an object cannot be instantiated and is not in the

Speaking of Spring AOP (aspect-oriented programming) is very familiar to the aspect programming (spring is not the focus of this blog post), but let me ask a few questions to see if the students understand that if you know, you can not continue to read:1. What are the implementation methods of Spring AOP?2. Why use dynamic agents?3. How are they implemented?4. What is the difference between them?In the following, spring uses dynamic proxy to implement AOP, specifically using the JDK Dynamic

Spring1.2:the transaction Agent factory [Transactionproxyfactorybean] or automatic proxy interceptor [Beannameautoproxycreator] the Proxytargetclass property, set to True, uses the cglib proxy, which defaults to false, using the JDK dynamic proxy. the following references Spring Framework reference 2.0.5:Spring2.0:The Spring AOP section uses JDK dynamic proxies or cglib to create proxies for target objects. (It is recommended that you use the JDK

First, what is a dynamic agent?First we think about what is an agent? For example, in the real life of the boss on a business trip, you can not do something in the company, please his secretary "agent". In the program "agent" means that the original is a dry thing, but for some reason is not convenient to carry out, bu
