publishers and consumers. the publishers produce the messages, the consumers pick them up and process them. it's the job of the Message Broker (such as rabbitmq) to ensure that the messages from a publisher go to the right consumers. in order to do that, the broker uses two key components: exchanges and queues. the following dimo-shows how they connect a publisher to a consumer: As you can see, the setup is pretty straightforward.

Recent work I'm doing a have about message sending and receiving encapsulation work. The process is like this, the message middleware is the use of RABBITMQ, in order to ensure absolute loss of the message, we need to send and receive the message before the DB landed. Before sending, I will first do a DB insert, single table insertion, so in the performance is also acceptable, single table insert did the pressure measurement is basically one to two mi

Are you struggling with the problem of calling and communicating between different processes of heterogeneous systems? If so, congratulations, the messaging service makes it easy for you to solve these problems.The Messaging service specializes in solving data exchange (message notification/communication) issues between mul

Supplier barriers maintain a high enough price and profitability, and only large organizations can use MQ. In order to break the barrier, so that the same application can consume different MQ products, 2001, JMS was born. JMS provides a common API interface that hides the actual interface of each

Use Python to learn RabbitMQ message queues, RabbitMQ can be used as a message proxy. The core principle of RabbitMQ is very simple: receiving and sending messages. You can think of it as a post office: We put the mail into the mailbox, the postman will deliver the mail to your recipient. RabbitMQ is a combination of e

RABBITMQ is a complete, reusable enterprise messaging system based on AMQP. He follows the Mozilla Public License open source agreement.MQ is all called the message queue, and Message Queuing (MQ) is an application-to-application communication method. Applications communicate by reading and writing messages to and from the queue (data for the application), without requiring a dedicated connection to link them. Message passing refers to the process of
