choose from for different language clients, but because memcached has been developing for a longer period of time, many of Memcached's clients are more mature and stable in terms of client support at present. and Redis because its protocol itself is more complex than memcached, plus the author constantly add new features, and so on, the corresponding third-party client tracking speed may not catch up, sometimes you may need to make some changes on the basis of third-party clients to better use.

Use JavaScript to build a simple PubSub system Summary: In a recent build of a Web push service project, I want my UI to respond to application-level events (semantically, if you would) because there are several components that need to get information from the system, but do not depend on each other, and I want them

Pubsub is a message communication mode. It mainly aims to decouple the coupling between the message publisher and the message subscriber, which is similar to the observer mode in the design mode. Pubsub not only addresses publisher and Pub/sub is a message communication mode. The main purpose is to decouple the coupling between the message publisher and the message subscriber, which is similar to the observ

This period of time the message bus was re-refactored. This refactoring mainly focuses on the components of the message bus and the simplification of the pubsub client, as well as some ideas about the message bus. Simplifying the complexity of the clientThe previous client needs to connect two distributed components at the same time. Access to the message bus requires the user to provide the pubsuberHost pubsuberPort parameters, so it first connects

Recently, bloggers are doing a small project, introducing a third party JS file, which will call XMLHttpRequest to send AJAX requests to the server, but I have the need to listen to some of its Ajax request events, in order to execute additional scripts. So, look at the event method that listens for Ajax request slightly, here share to everybody. If the AJAX request was initiated by JQuery's $.ajax, the Ajax event handlers can be heard by default in jquery's Global Ajax events, but I encountere

Framework Introduction: openfire is developed in Java and the open-source RTC server is based on the XMPP (jabber) protocol. You can use it to easily build an efficient Instant Messaging Server. openfire is easy to install and use and manage on the web. A single server supports tens of thousands of concurrent users. Because the XMPP protocol is open, you can use various IM client software that supports XMPP protocol to log on to the service. Framework advantages • fully implemented in Java langu

The user profile picture is called "Avatar" in jabber, And the JEP-0084 defines a method that complies with the XMPP protocol to transmit profile picture information, the Protocol is built on the personal eventing via pubsub [2] subset ("pep") of pubsub. In addition, the Avatar avatar can also be stored using vCard, for example, PSI uses vCard.There are currently fewer clients using the JEP-0084.In addition

IntroducedThe observer pattern, also called the Publish subscription pattern (Publish/subscribe), defines a one-to-many relationship that allows multiple observer objects to listen to a Subject object at the same time, notifying all observer objects when the state of the subject changes, so that they can automatically update themselves.Benefits of using the Observer pattern: Supports simple broadcast communication and automatically notifies all subscribed objects.
