• A client publish a message to the Redis channel
• Servers subscribe to the channel and handle the message

Run

• Start Redis and the server

make run

• Publish messages with the client

make run-client

You should see the following server logs:

listening message...

Received data: Message { id: 1, action: Download }
Received data: Message { id: 1, action: Download }
Received data: Message { id: 1, action: Download }
Received data: Message { id: 1, action: Download }
Received data: Message { id: 1, action: Download }
