Important notes
Publisher Consumer
‣ creates a relationship between queues and exchanges ‣ contains criteria and properties ‣ can be created at runtime by consumers
‣ store messages ‣ named ‣ bound-able to exchange ‣ criteria ‣ can be created at runtime by consumers
‣ routes messages based on criteria ‣ doesn’t store messages ‣ can inspect message content ‣ can be created at runtime consumers
‣ can create exchanges and queues
‣ can create exchanges and queues
