Throttle messages for a slow consumer
=====================================

This example shows how to throttle messages that are published are a rate faster than
what a slow consumer (subscribed) can process. In this example, only the newest messages
are preserved, messages that cannot be consumed on time are dropped.

In the console, you should see gaps in the sequence of messages, because the publisher is
producing messages every 0.001 seconds, but we configure a queue of length 1, with a
throttling of 600ms to give time to our slow consumer. Without this throttling, the consumer
would process increasingly old messages.
