What is a channel?

A channel is a mechanism created by the server for the organization and transmission of messages. Users can define channels as a topic, queue, routing key, path, or subject depending on the protocol used.

Why do we need channels?

Channels play a crucial role in communication between producers and consumers. A producer can send a message through the channel, and the consumer receives messages from a particular channel. A channel's sole purpose is to ensure the right messages route to the right consumers.

The diagram above shows the communication between a producer and consumer, with the producer sending a message through the channel. The channel then queues the message to the specific consumer.
