Pro Tips

Use PSUBSCRIBE with patterns (channel:*) to subscribe to multiple related channels.

Pub/Sub is fire-and-forget. Use Streams if you need message persistence and replay.

Messages are lost if no subscribers are connected. Pub/Sub has no persistence - use Streams for durability.

Subscribed connections can't run other commands. Use separate connections for pub/sub.
