Exploring the Competing Consumers pattern with Azure Service Bus

Imagine a queue of notifications waiting to be processed.

A producer keeps adding messages, while one consumer processes them one at a time.

Producer
   |
   v
┌───────────────┐
│ notifications │
└───────┬───────┘
        |
        v
    Consumer

If messages arrive faster than processing them, the queue starts to grow.
