First, using the array cache Subscriber subscription message, when the Subscriber subscribes to the message, push the subscription message to the queue of the specified message, and when the publisher publishes the message, we traverse the execution push to the specified message queue for the callback event.varPubsub= (function(){ vareventobj={}; return{subscribe:function(EVENT,FN) {eventobj[event]=fn}, publish:function(event) {if(Eventobj[event]) eventobj[event] (); }, off:function(EVENT,FN)

Redis source code analysis (30th) --- pubsub publish and subscribe Mode Today I learned the term "Publish and subscribe mode" in Redis, which was first introduced to JMS (Java Message Service) java Message Service. I subscribe to these types of messages. Only when these types of messages are broadcast and sent Will I filter other messages directly, this ensures an efficient transmission efficiency. Next, let's take a look at how Redis achieves this pu

In recent time, the development of message bus feature was postponed, and some time was spent to optimize and reconstruct the original pubsub mechanism. Here is a record of the optimization process and how it has changed compared to the original design.The role of pubsub within the message busPubSub is primarily used within the message bus for real-time control of all online clients. Each client in the use

NANOMSG Experiment--pubsubThe Publish subscription model is a common feature provided by many message middleware. The message mechanism enables the message publisher and the message to receive (consume) peopleTo decouple. PubSub mode is also one of the message models directly supported by NANOMSG, so through the PubSub model experiment,At the same time, we also have a general understanding of the basic usag

Today, I learned about the tall noun in Redis, "Publish subscription Mode", the word Publish subscription mode was heard in the JMS (Java message Service) Java Messaging Service when I first heard about it. This ranking in a popular point of saying, is that I subscribe to this type of message, when only this kind of message broadcast sent, I will, other messages directly filtered to ensure an efficient transmission efficiency. Let's cut to the chase and learn how Redis implements this publish su
