The principle of RabbitMQ Cluster Scheme

RabbitMQ itself is written based on Erlang, and the Erlang language is inherently distributed (achieved by synchronizing the erlang.cookie of each node of the Erlang cluster). Therefore, RabbitMQ naturally supports clustering. Clustering is a way to ensure reliability, and it can be scaled horizontally to increase message throughput.

The following figure shows an example of a cluster:

The above figure uses three nodes to form a RabbitMQ cluster. The metadata information of Exchange A (switch) is consistent on all nodes, while the complete data of Queue (the queue where messages are stored) will only exist on the node it created. The other nodes only know the metadata information for this queue and a pointer to the owner node for queue. The above content is what is the principle of RabbitMQ cluster? have you learned any knowledge or skills?
