kafka producer and consumer

Wait (), notify (), and Notifyall () are all methods of the Java base class Java.lang.Object.Popular explanationsWait (): Waits for another thread to wake up on the current thread.Notify (): Wakes up a thread that is waiting for this object's monitor.Notifyall (): Wakes up all the threads waiting on this object monitor.These three methods are the underlying mechanism provided by the Java language to implement inter-thread blocking (Blocking) and control in-process scheduling (inter-process commu

Consumer issues, also known as limited buffer issues. Two problems to be solved: 1. Synchronize (save and retrieve) Resources in the buffer zone) 2. When the buffer zone is full, it cannot be stored and the producer needs to wait. When the buffer zone is empty, it cannot be obtained and the consumer needs to wait. Solution: For Question 1: Add synchronized to the

Before I say the producer-consumer model, I think it is necessary to understand the obj.wait () and the Obj.notify () method. The wait () method means that when a thread holding an object lock calls this method, the object lock is freed and the thread is dormant. The Notify () method is to hold the same object lock to wake the dormant thread, making it eligible to preempt the CPU. Can understand the synchro

The producer-consumer model is a classic multithreaded design pattern that provides a good solution for multithreaded collaboration. In producer-consumer mode, there are usually two types of threads, that is, several producer threads and several

1 // The standard idiom for calling the wait 2 synchronized (sharedobject) {3 while (condition) {4 sharedobject.wait (); releases lock, and reacquires on Wake up5 }6 // do action based upon condition e.g. take or put to queue 7 }Canonical code template using the wait and notify functions.The purpose of using wait in the while loop is to check whether the condition is satisfied before and after the thread is awakened, and if the condition is not changed,

A good solution in multithreading is the producer consumer mode! In the producer consumer mode, there are usually two types of threads, namely many producer threads and many consumer threads. The production thread is responsible f

[Python journey] Article 6 (v): producer and consumer models implement multi-thread asynchronous InteractionAlthough the title is "producer-consumer model achieves multi-thread asynchronous interaction", this should also include the Python message queue, because the multi-thread asynchronous interaction is implemented

Producer Consumer Issues(English:Producer-consumer Problem), also known asLimited buffering issues(English:Bounded-buffer Problem), is aMulti-threaded synchronizationThe classic case of the problem. This issue describes two shared fixed sizeBufferThreads--The so-called "producer" and "

In multi-threaded and concurrent tool classes, one common idea is the producer-consumer model, where producers are responsible for producing goods, placing items on conveyor belts, and consumers are responsible for acquiring conveyor belts and consumer goods. Now consider only the simplest case where only one item is allowed on the conveyor.1, the belt is empty,

suspend the wait, you can call Sem_trywait (). The Sem_post () can free up resources (v operations), increase the value of semaphore by 1, and wake up the pending thread.II. realization of producer-consumer issues(1). This example mainly uses the annular buf and the signal quantity to realize the single consumer, the single
