1.1 Introduction to the contents of this sectionThis part we are going to send a message to multiple consumer, which is called "Publish/subscribe"The way we do this is the sending side, sending a message, and at the same time, multiple receivers will receive the message and print it on the screen at the same time.1.2exchange IntroductionIn the previous blog post, we explained that the sender sends a message to the message queue and the receiving side obtains the message from the message queue.

Remember the first time to do the Java problem, see "write producer consumer problems", but also think it is related to the factory model. Now it is thunder to think about it.Java's producer consumer problem is the multi-threaded concurrent operation of the same resource buffer, when the resource buffer is full, the thread continues to add data, you should make it wait, there is space to send a message noti

What is the producer consumer modelSome modules are responsible for production data, which is handled by other modules (the modules here may be: functions, threads, processes, etc.). The module that produces the data is called the producer, and the module that processes the data is called the consumer. The buffer between producer and consumer is called a warehous

Producer and consumer mode 1. QueueAdvanced First Out2. StackAdvanced Post-outA synchronized, thread-safe queue class is provided in the Python queue module, including FIFO (first-in, first-out) queue Queue,lifo (back-in-first-out) queue Lifoqueue, and priority queue priorityqueue. These queues implement the lock primitives (which can be understood as atomic operations, i.e. either not done or done) and can be used directly in multiple threads. Queues

Before I felt very simple, but one interview let me write on the paper, actually did not write to disgrace ah.Producer consumer problem (Producer-consumer problem): Producers constantly produce products, consumers take away the products produced by producers. The producer produces the product and puts it into an area where consumers remove data from it.The problem: to ensure that producers do not add data w

Producer-consumption patterns, which typically have two types of threads, that is, several producer threads and several consumer threads. Producer threads are responsible for submitting user requests, and consumer threads are responsible for dealing specifically with the tasks submitted by the producer. The two communi

function to achieve a minus 1 of the semaphore. When using the Sem_wait function, blocking occurs if the semaphore count is 0. It is not returned until the signal has been successfully reduced by 1 or interrupted by a signal. You can use sem_trywait to avoid blocking. When Sem_trywait is called, if the semaphore is 0, it is not blocked, but returns-1, and the errno is set to Eagain.4.int sem_post (sem_t *sem)We can call it the semaphore increases by 1.Let's take a look at a

This is a common mode for Java Development. It allows the program to call each other between producers and consumers during design. Three objects need to be created in the mode: producer consumer warehouse Producer: Put the products produced into the total warehouse Consumer: extracts products from the warehouse for consumption. Warehouse: A synchronization method is used to lock and synchronize the wareho
