Point to point messaging System

< What is a messaging system in Kafka?

Publish-subscribe messaging System >

In point to point system, a specific message can be consumed by only one consumer and it will instantly disappear from the queue once it is read.

However, one or more consumers can consume it in a queue as messages remain in the queue for some time. For instance, in an order processing system, each order is processed by one particular Order Processor. This also implies that multiple Order Processors can work at the same time.
