Redis: how (or should) I delete pubsub channels

Question

In my application, I dynamically create new pubsub channels, and maybe too many, for example, 5k per day. According to my application requirements, any channel is used for no more than 5 minutes.

Given this situation, thousands of thousands of unused channels will be present in the application in a week. So how can I delete unused channels or even delete them. Are they stored in memory? What happens to messages published through them, they remain in redis memory?

thanks

Channels surround. They exist only by subscription. So: either call [P] UNSUBSCRIBE from the connected signatures, or close the signed connections.
