1. Background Recently, due to project requirements, Kafka's producer needs to be used. However, for C ++, Kafka is not officially supported. On the official Kafka website, you can find the 0.8.x client. The client that can be used has a C-version client. Although the client is still active, there are still many code problems and the support for C ++ is not very good. There is also the C ++ version. Although the client is designed according to the i

Today we are going to introduce the "producer/consumer model", which can be used in many development fields. This mode is very important. I plan to introduce it in several posts. Today, I am going to talk about literacy. If you know more about this mode, skip this literacy post and read the next post (for specific applications of this mode). You may have heard of this in the 23 modes of the four-person gang (gof! In fact, the 23 classic gof models a

This blog is a previous Java Multithreading (iii) Producer consumer model and the implementation of the method complement. The producer consumer model is implemented in three methods (lock, synchronized, blocking queue). The specific content is: The producer produces the random number (in order to facilitate the reading result, I limit the random number to 10 int

queue in a producer does not cause the get () method to return an error. 3 Q.join_thread (): The background thread that connects the queue. This method is used to wait for all queue items to be consumed after the Q.close () method is called. By default, this method is called by all processes that are not the original creator of Q. Calling the Q.cancel_join_thread method can prohibit this behaviorApplication:The multiprocessing module supports two mai

　　Producer Consumer issues (Producer-consumer problem) is a classic case of multithreaded synchronization issues. The problem describes two threads that share fixed-size buffers-the so-called "producer" and "consumer"-problems that can occur when they actually run. The primary role of the producer is to generate a cert

(a), the problem of the leadThere is a data storage space, divided into two parts, one for storing the person's name, and the other for storing the person's gender;Our application consists of two threads, one thread keeps adding data (producers) to the data storage space, and the other thread pulls the data out of the data space (consumer);Because of the thread uncertainty, there are two scenarios:1. if the producer Line Cheng Gang adds a person's nam

This article turned from programming blog: http://program-think.blogspot.com/2009/03/producer-consumer-pattern-0-overview.html Today we will introduce the "producer/consumer model", which can be used in many development fields. Some may have been confused: I have never heard of this in the 23 Gang of Four models! In fact, the 23 classic gof models are mainly based on OO (from the title of design patter

condition variable. if the condition variable is statically allocated, you can also use a macro to define PTHEAD_COND_INITIALIZER for initialization. use pthread_cond_destroy to destroy the condition variable. if the condition variable is successfully returned, 0 is returned. A condition variable is always used with a Mutex. A thread can call pthread_cond_wait to block the wait on a condition variable. this function performs the following three steps: 1. release Mutex 2. blocking wait 3. when a

The recent need to use multithreading to implement a feature in a project is similar to the producer consumer model, thus learning the multi-threaded implementation of the producer consumer model. In the producer consumer model, there are usually two types of threads,That is, a number of producer threads and several co

Producer-Consumer issues (Producer-consumer problem), also known as limited buffering issues (Bounded-buffer problem), are a classic problem in the multithreading world, and can be described as: two or more threads sharing the same buffer, One or more of these as "producers" will continuously add data to the buffer, and one or more of the data to be taken from the buffer as "consumers". The key to this prob

does not store elements. 2. Producer Consumer ModelThe blocking queue supports the producer-consumer model, which separates the process of "finding what needs to be done" from the "execute work" and putting the work items into a "to-do" list so that they can be processed later rather than immediately after they are found. The producer-consumer model simplif
