This uses the real-time computed model--storm. Here are the main things to share today, as shown below: Data consumption

1. What is Kafka?Kafka is a distributed MQ system developed and open-source by LinkedIn. It is now an incubator project of Apache. On its homepage, Kafka is described as a high-throughput distributed MQ that can distribute messages to different nodes.

1) Queue Manager The queue manager is a top-level concept in the MQ system. It provides queue-based message services for us. 2) messages In MQ, we define the data transmitted by the application to MQ as a message. We can define the message content and give a broad understanding of the message, for example: various types of data files of the user. The processing r

IBM WebSphere MQ Basic ConceptsBasic concepts1. Queue ManagerThe queue Manager, as its name implies, is the management of Message Queuing, which ensures that messages in the queue are sent to the correct receive queue, or that messages are delivered to another queue manager. The Queue Manager generates the appropriate completion code for each invocation or command.The tasks that the Queue Manager performs are: Start Channel Handling MQI C

To facilitate future implementation on AIX 5L, I use the Windows XP command method to describe the process. The experiment was conducted as a demonstration for the company in Wednesday.

Concepts and terminology Messages, all referred to as message, refer to the transfer of data between the producer, the server, and the consumer.

 Transferred from: http://hi.baidu.com/lubezhang/blog/item/bd308b3b7ecce3ec14cecb4f.html IBM MQ (IBM message Queue) is IBM's commercial messaging intermediary product for distributed computing environments or heterogeneous systems. Message 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

1. Background information Many of the company's platforms generate a large number of logs (typically streaming data, such as the PV of search engines, queries, etc.), which require a specific log system, which in general requires the following characteristics: (1) Construct the bridge of application system and analysis system, and decouple the correlation between them; (2) support the near real-time on-line analysis system and the off-line analysis system similar to Hadoop; (3) with high scalabi
