Exchanger (Exchange)The switch is like a router, we first send the message to the exchanger, and then the switch based on the BIND key (binding key) and the producer sends the message when the routing key Routingkey,Exchange types (fanout,direct,topic) deliver messages to the corresponding queue by Exchange type. (It is important to understand this concept, which

implies, a memory node places all data in the memory, and a disk node places data in the disk. However, as mentioned above, if message persistence is enabled during message delivery, data is stored securely on disks even on Memory nodes. A rabbitmq cluster can share user, vhost, queue, exchange, and so on. All data and statuses must be copied on all nodes. An exception is, the message queues of the nodes t

First, the basic concept of a detailed introduction1. IntroductionHave you ever encountered two (multiple) systems that need to synchronize certain data through a timed task? 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 n

. In fanout mode, the specified Routing_key is not valid. Topic: Any messages sent to topic Exchange will be forwarded to all queues that are concerned with the specified topic in Routing_key 1. This mode is more complex, simply put, is that each queue has its own topic of interest, all messages with a "title" (Routing_key), Exchange will forward the message to all the topics of interest can match the Routi

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

The distributed communication security policy for Erlang can be attributed to all or None.

, '/', credentials)) #创建频道channel = Connection.channel () # declares a message queue, The message will be passed in this queue. If a message is sent to a queue that does not exist, RABBITMQ will automatically clear the messages. If the queue does not exist, create a channel.queue_declare (queue= ' hello ') #exchange-it allows us to specify exactly which queue the message should go to. #向队列插入数值 Routing_key i

the declared exchange still exists.When the message enters the A-node queue, consumer pulls from the B-node, RABBITMQ temporarily transmits the message between A and B, takes the message entity in a and sends it to the consumer by B.So consumer should try to connect to each node and fetch messages from it. That is, for the same logical queue, a physical queue is established on multiple nodes. Otherwise, wh
