push一端具有负载均衡功能,pull一端可以多启动几个实例,均衡执行task,若中途pull一端挂掉,则push自动把任务分发到其他pull上。 二、 pub/sub模式 A程序代码如下: pub_Queue =Queue.Queue() context=zmq.Context() publisher=context.socket(zmq.PUB) publisher.bind("tcp://*:5557")whileTrue: publisher.send_...
ZeroMQ 使用套接字作为消息通信的端点。套接字具有多种类型,如REQ/REP、PUB/SUB、PUSH/PULL等,每种类型都有不同的通信模式和语义。 3.2.4 消息传递模式 ZeroMQ 提供了多种消息传递模式,包括请求/响应、发布/订阅、推送/拉取等。这些模式定义了消息的传递方式和顺序,开发者可以根据应用需求选择适合的模式。 3.2...
Pub socket用来发送数据,将数据以fan-out(扇出,一对多)的形式发送给它所连接的所有Sub socket上。 当Pub socket因为达到HWM或者bind后没有connect这两种原因进入mute状态时,对于应用层而言,zmq_send()不会阻塞,但是zmq底层会将所有发送的数据丢弃(也就是上面提到的,对于应用层,Pub在发送数据时不会去管Sub是否存在,...

There are at least two advantages of the PUSH-PULL and PUB-SUB design. First, there is no need to keep the connection alive between the server and the client. As a client, you just put the data to the predefined location, job’s done. You know someone (the server) will pick it up...
