kafka mq

1. Compliance with JMS specifications MQ complies with the JMS specification and Kafka does not follow the JMS specification. Kafka uses file systems to manage the lifecycle of messages 2. Throughput Kafka is a sequential write disk, so the efficiency is very high. Kafka

I. Some concepts and understandings about Kafka Kafka is a distributed data flow platform that provides high-performance messaging system functionality based on a unique log file format. It can also be used for large data stream pipelines. Kafka maintains a directory-based message feed, called Topic. The project called the release of the message to topic was a

I have studied RABBITMQ before and have installed it. the articles for the installation record are as follows:Erlang:http://www.cnblogs.com/charlesblc/p/5512380.htmlRabbitmq:http://www.cnblogs.com/charlesblc/p/5516585.htmlAs you can see, good memory is inferior to bad writing. Still have to record!In addition, the classification is particularly important, with the title search RABBITMQ is not found at all, from the "Installation Deployment" category only found. so the classification is still to

Apache下的一个子项目。 类似于ZeroMQ，它能够以代理人和点对点的技术实现队列。同时类似于RabbitMQ，它少量代码就可以高效地实现高级应用场景。RabbitMQ、ZeroMQ、ActiveMQ均支持常用的多种语言客户端 C++、Java、.Net,、Python、 Php、 Ruby等。Jafka/Kafka Kafka是Apache下的一个子项目，是一个高性能跨语言分布式Publish/Subscribe消息队列系统，而Jafka是在Kafka之上孵化而来的，即Kafka的一个升级版。具有以下特性：快速持久化，可以在O(1)的系统开销下进行消息持久化；高吞吐，在一台普通的服务器上既可以达到10W/s的吞吐速率；完全的分

Kafka is a distributed MQ system developed by LinkedIn and open source, and is now an Apache incubation project. On its homepage describes Kafka as a high-throughput distributed (capable of spreading messages across different nodes) MQ. In this blog post, the author simply mentions the reasons for developing

Introduction The IBM®WEBSPHERE®MQ environment is powerful and involves many object definitions. Allowing automated checks of these object-defined systems helps speed the development and debugging of WebSphere MQ networks. WebSphere MQ Explorer is the name of the WebSphere MQ administrative toolset that you can use to

listener is registered, the listener's OnMessage method is automatically invoked once the message arrives. An MDB (Message-driven Bean) in an EJB is a messagelistener. In-depth learning of JMS is a great help in mastering the Java Architecture and EJB architecture, and message middleware is also a necessary component of a large distributed system. This sharing mainly makes the overall introduction, the concrete depth needs everybody to study, the practice, the summary, grasps. V. Common message

A very important design principle of distributed systems is loose coupling, that is, minimizing dependencies between subsystems. In this way, subsystems can evolve, maintain, and reuse independently of each other. Message Queue (MQ) is a good means of decoupling. For more information about the role of MQ in system integration, see the enterprise integration patterns (EIP) book or corresponding website. Simp

WebSphere MQACTIVEMQ WebSphere MQ 1, the middleware in the application software and system software, is a complex in exchange for enterprise application simplification of the reusable basic software, it uses the system software provided by the basic services (functions), connecting the network application system of various parts or different applications, to achieve resource sharing, The purpose of feature sharing. 2, Three kinds of co

Webservice and MQ (MessageQueue) are common means of solving cross-platform communication, what are the differences between them?personally, the most essential difference is that webservice near real-time communication, while MQ is usually delayed communication. What do you mean? Because WebService is actually the local server program calls the method on the remote server, the interaction between the two, t

First, MQ1.1 About Message Queuing MQMessage Queuing (MQ) is an application-to-application communication method. Applications communicate by writing and retrieving data (messages) for applications that enter and leave the queue, without requiring a private connection to link them. Message passing refers to the process of communicating between programs by sending data in a message, rather than by directly invoking each other, and directly invoking tech

Http://www.ibm.com/developerworks/cn/opensource/os-cn-kafka/index.html Message QueuingMessage Queuing technology is a technique for exchanging information among distributed applications. Message Queuing can reside in memory or on disk, and queues store messages until they are read by the application. With Message Queuing, applications can execute independently-they do not need to know each other's location, or wait for the receiving program to receive

on the subject or content. The Publish/Subscribe feature makes the coupling between sender and receiver looser, the sender does not have to care about the destination address of the receiver, and the receiver does not have to care about the sending address of the message, but simply sends and receives the message based on the subject of the message. Cluster (Cluster): To simplify system configuration in point-to-point communication mode, MQ provide

Today, social networks are ubiquitous-to connect with friends, to keep up with the times, or to keep people informed of the latest developments in topics of common interest. Social networking is also useful in businesses. This article will show you how to quickly and easily use social networking software (such as Twitter) in your WebSphere MQ application to send status and problem information to a wide range of system administrators or end users, or e
