This is a small example to show how NATS can be used to communicate with multiple instances of the same service in a queue format.
- The client will make a request to any existing subscribers to the "greeting" event.
- Service 1 and Service 2 are both subscribers to the "greeting event", and belong to the same queue.
- When the example runs, only one service (whichever is fastest) will respond.
Run docker-compose up to run. Try running multiple times to see how sometimes Service 1 will respond, but other times Service 2 will respond.
