transferred, can be anything (C # programming is a byte array), label is a description of the transfer data, such as routing key, persistent delivery Mode Message persistence. If the exchange,queue,message is persistent, the message will be retained after the RABBITMQ reboot, and any link is not persisted and the message will not be restored. Persistence can reduce throughput by up to 10 times times

RabbitMQ original translated 05 -- routing, rabbitmq translated 05 -- Routing In the previous article, we built a simple log system that can broadcast messages to multiple recipients. In this article, I will add some functions to make it possible to accept some messages. For example, we only record error messages on disk, at the same time, all messages can be printed to the screen.Bind In the previous case,

Tutorial on the official website of RabbitMQ --- route, official website of rabbitmq --- route (Use python client pika 0.9.8) In the previous tutorial, we built a simple log system. We can broadcast log messages to many recipients. In this tutorial, we will add a feature to it-we will subscribe to only one message subset as possible. For example, we can direct only error messages to log files (saved to dis

In the previous section, the concepts such as exchange, routingkey, and queue of RabbitMQ are described in detail, and the code for sending and processing messages using PHP is illustrated. This section describes how to use PHP multithreading to process messages in real time in the project, and briefly introduces the installation of RabbitMQ. If you are familiar with it, skip this part. 1.

RABBITMQ Chinese translation, the main is the MQ letter: Message queue, that is, the meaning of messages queuing. There is also a rabbit word, that is, the meaning of the rabbit, and Python language is called Python, the foreigner is quite humorous. RABBITMQ services are similar to MySQL, Apache services, but offer different functions. RABBIMQ is used to provide a service for sending messages that can be us

Basic.qos method with the prefetch_count=1 setting. This tells RabbitMQ not to give more than one message to a worker at a time. Or, in other words, don ' t dispatch a new message to a worker until it has processed and acknowledged the previous ONE.
