> What Redis offers with Pub/Sub is a listener model, where each subscriber receives each messages when it is listening, but won't receive them when not connected. We want every consumer to eventually receive all messages, independently of their online or offline status.
> In a clustered environment where you have multiple instances of your consumer component (application) running at the same time, each instance would receive each message produced on the channel. This library makes sure any given message is consumed once per logical consumer, even when multiple instances of this component are running.
