> Per [KIP-266|https://cwiki.apache.org/confluence/display/KAFKA/KIP-266%3A+Fix+consumer+indefinite+blocking+behavior], the {{Consumer.poll(long timeout)}} method was deprecated back in 2.0.0. 
> In 3.7, there are two implementations, each with different behavior:
> * The {{LegacyKafkaConsumer}} implementation will continue to work but will log a warning about its removal
> * The {{AsyncKafkaConsumer}} implementation will throw an error.
> In 4.0, the `poll` method that takes a single `long` timeout will be removed altogether.
