1. What is Pub/sub
Pub/sub function (means Publish, Subscribe) is the publishing and subscription function. In an event-based system, Pub/sub is a widely used communication model that uses events as a basic communication mechanism to provide loosely coupled interaction patterns required by large systems: subscribers (such as clients) express an event or a class of events that it is interested in receiving by means of event subscriptions; publishers s
my idea is to get a unique identifier for the current subscription number when the user orders in one of the subscription numbers. When the order is generated, an identity is inserted into the database.
Now there is a requirement, that is, multiple subscription numbers are common to one site, but make a difference when you order.So, I hope you pass by friends t

A publish Subscription (PUB/SUB) is a message communication pattern that is primarily designed to decouple the coupling between a message publisher and a message subscriber, which is similar to the observer pattern in design patterns. Pub/sub not only solves the direct code level coupling between publishers and subscribers, but also solves the coupling between the two on the physical deployment. As a pub/sub server, Redis serves as a message routing f
