Preface: based on the previous articles, this article has made a lot of in-depth changes, but thrift/RPC has the same communication principle. Thrift-client implementation: I. thrift_pool class:1. Create the tTransport class as follows:Shared_ptr {/* Use TCP socket for data transmission */Shared_ptr /* Set timeout */Socket-> setconntimeout (thrift_time_out );Socket-> setsendtimeout (thrift_time_out );Socket-> setrecvtimeout (thrift_time_out );/* Buffer transport data */Shared_ptr Shared_ptr Tran

is reached. The timeout channel would eventually is deallocated by the garbage collector. (In this example we used to time.Sleep demonstrate the mechanics of goroutines and channels. In the real programs you should use ' time. After ', a-function that returns a channel and sends-on-channel after the specified duration.) Let's look at another variation of this pattern. In this example we has a program that is reads from multiple replicated databases simultaneously. The program needs only one of

13. Web Stress Test-httperfHttperf is more powerful than AB and can test the maximum number of services a Web service can carry and identify potential problems, such as memory usage and stability. Maximum advantage: You can specify a regular pressure test to simulate the real environment.Download: http://code.google.com/p/httperf/downloads/list [Email protected] ~]# tar zxvf httperf-0.9.0.tar.gz [Email protected] ~]# CD httperf-0.9.0 [Email protected] httperf-0.9.0]#./conf

If you want to start, this hash table is larger, you can adjust the-o parameter.In the hash table, memcached key as key,value is the item pointer, not item value. 　　2.4: Initialize the connection.Conn_init ()That is, the-c parameter in the memcached startup parameter, which defaults to 1024.In order to find connection fd (file descriptor) more quickly, the connection of the application will actually be larger than

that uses the XMLSocket class. JavaScript communicates with the server-side socket interface by invoking the set of interface interfaces provided by this Flash program. JavaScript can easily control the display of the contents of an HTML page after it receives information that is sent in XML format on the server side.7.Java Applet Socket InterfaceThis thing is similar to flash, but I do not understand, I will not elaborate.Third, back-end processing modeThis article is mainly to summarize the v

a list (year, temperature, for example, [(1950, 10), (1960, 40), (1960, 5)]. Sort phase Sort the data output by mapper. You can use jobconf. setoutputkeycomparatorclass to set your own sorting rules. In this example, after sorting, the output list set is the list (year, temperature) sorted by year, such as [(1950, 10), (1950, 5 ), (1960, 40)]. Combine phase In

, dbinputformat, and sequencefileinput. You can use jobconf. setinputformat. This process should also include dividing the input data by Task Granularity (split) and passing it to mapper. In the temperature example, because all text data is processed, use the default textinputformat for the input format. MAP Phase Processes the Input key and value pairs. The output is a set of key and value, that is, map (K1, V1)-> List (K2, V2), which uses jobconf. setmapperclass: set your own mapper. In this

others have made several improvements to the reference counting algorithm, which makes the reference counting algorithm and its variants (such as the delay Counting Algorithm) in a simple environment, or in some modern garbage collection systems that integrate multiple algorithms, you can still show your skills. 2. Mark-Sweep Algorithm The first practical and perfect garbage collection algorithm is the Mark-clearing algorithm. It was proposed by J. McCarthy, inventor of Lisp in

today, will we use it for programming? Guan Gu and Zhijin. IfToday's programming languages will be available in 1960. Will people use them at that time? In some ways, the answer is no. Today's programming languages rely on hardware inJanuary 1, 1960 does not exist. For example,In a language like python, correct indentation (Indentation) is very important in writing,In
