RABBITMQ is a complete, reusable enterprise messaging system based on the AMQP protocol standard. It follows the Mozilla Public License Open Source protocol, an industrial-grade Message Queuing (MQ) server implemented with Erlang, and Rabbit MQ is built on the Erlang OTP platform.

RabbitMQ is a popular open-source message queue system developed in erlang language. it fully implements AMQP (Advanced Message queue protocol ).

1. What is RABBITMQMQ (Message queue): A queue of messages that is designed by the server to store a large number of messages and provides a way for the client to operate the queue: the production queue (adding data to the queue), the consumption queue (fetching data from the queue). RABBITMQ is a typical application based on Message Queuing. RABBITMQ In addition to the normal production and consumption
RabbitMQ (2), rabbitmq
The last time RabbitMQ was installed and vhost and user were successfully created, but the production and consumption processes were not completed yet. This time, we called this process.
The main problem last time was that the Process Code was not compiled and saved, which is actually a Python program. In the past two days, I have read the
Preface: Here I will use Java to implement the RABBITMQ simply. Below we take the following question to step by step understanding and learning rabbitmq.1: What should we do if the consumer connection is interrupted?2: How to do load balancing3: How to effectively send the data to the relevant recipients? is how to filter4: How to ensure consumers receive complete and correct data5: How to get high priority
Run and manage RabbitMQ.
Server Management. RabbitMQ is written in Erlang, similar to Jave,Erlang also provides virtual machines,Erlang By nature, the application does not need to know whether or not to communicate with each other on the same machine, which makes RabbitMQ 's cluster and message routing easier. Multiple apps can run on the same node

RabbitMQ Server will send this information to the next consumer.
If the app has bugs and forgets the ACK, then RABBITMQ server will no longer send data to it because the server considers the consumer processing power Limited.
