Let's say on twitter, a celebrity update her status, and it's pushed to all of her followers.
If we set up queue, where the publisher is service that fetches the celebrity's status, and the consumer are the individual followers. But with a million followers, whoever receives that message first will see the update, while others will not ? What is a common pattern to use here so that every one of her followers will see the update and not 'compete' with each other to consume the message first?
