I'm not sure if its a good idea to introduce this waiting time by default.
Imagine we are consuming slowly because downstream operations are
expensive. Then, we would introduce an artificial slowdown (in latency and
throughput). I would suggest to:
- Set the value by default to 0
- Only call sleep if the idle time is > 0.
