zeromq是一个高性能、异步消息传输库,它提供了多种消息传输模式,其中包括pub/sub模式。pub/sub模式是一种发布-订阅模式,用于在多个节点之间进行消息传递。 在C语言中,使用libzmq库可以实现zeromq的pub/sub模式。下面是一个简单的zeromq pub/sub示例: 代码语言:txt 复制 #include <stdio.h> #include <stdlib.h>...
redis pub sub c 实例 redis pub sub 性能 Redis pipeline与Pub/Sub Redis全称是 remote dictionary server ,本质上是一个key value类型的内存数据库,因为是纯内存的操作,Redis的性能非常出色,每秒可以处理超过10万次读写操作。但如果没用好,每秒10万次的读写效率也是发挥不出来的。而管道技术尤为显著提高了 redis...
Python 的 C 的 PubSub/观察者模式? Python's PubSub/observer Pattern for C++? 我正在寻找 Python PubSub 库的 C 替代品,其中我不必将信号与插槽等连接,而是可以注册一种特殊的消息,而无需知道可以使用的对象发送。 <铅> 你为什么不直接实现一个呢?这不是一个复杂的模式(好吧,取决于你真正想要什么)。无...

Redis的pubsub.c是对pubsub功能的实现。 Redis的pub/sub是一个稳定快速的消息系统。 基于ziplist和dict实现。 主要包含了消息的发布、订阅、取消订阅功能。 在server.h有如下属性: /* Pubsub */dict*pubsub_channels;/* Map channels to list of subscribed clients */list*pubsub_patterns;/* A list of ...
PUBSUB_PROJECT1=project-name,topic1,topic2:subscription1:subscription2 Push Subscriptions The subscription string can be used to create a push subscription by appending the push endpoint to it separated by a +. Example: PUBSUB_PROJECT1=project-name,topic:push-subscription+endpoint TODO: Push ...
As an example we have the main program and a thread and they use the pubsub library to communicate one with another. The main initializes the pubsub library usingps_init()and creates the thread: ...intmain(void) {ps_init();pthread_tthread;pthread_create(&thread,NULL,subscriber_thread,...
Figure 1 The pub/sub model in action We don’t have the space in this column to show all the screen shots and all the detailed steps, but you can find those on my blog. Here are some high-level steps to follow to create a SignalR application and host it in the cloud: Use Visual...
