> Currently, when ShareConsumerImpl-poll() times out with an empty response, the background thread does not automatically stop fetching from the broker. The ShareConsumeRequestManager keeps sending requests until it actually receives any data.
> This means we could continue fetching from the broker when we did not intend to and these records would unnecessarily start timing out sooner than we want.
> We can maybe stop sending fetch requests as soon as the user passed timeout completes on the application.
