RabbitMq中的连接和通道

原文

A connection (TCP) is a link between the client and the broker, that performs underlying networking tasks including initial authentication, IP resolution, and networking.

Connections can multiplex over a single TCP connection, meaning that an application can open “lightweight connections” on a single connection. This “lightweight connection” is called a channel. Each connection can maintain a set of underlying channels.

推荐

Use long-lived connection
Separate the connections for publishers and consumers
Don’t share channels between threads

We recommend that each process only creates one TCP connection and uses multiple channels in that connection for different threads.
