------------------------------------

Thanks for the ticket. Are there any concrete use cases for blocking on the assignment?

> In 2.0, the KafkaConsumer poll(long) was deprecated and replaced with a poll(Duration). The poll(Duration) does not block for consumer assignments.
> Now, there isn't a blocking method that can get consumer assignments.
> A new KafkaConsumer method needs to be added that blocks while getting consumer assignments.
> The current workaround is to poll for a short amount of time in a while loop and check the size of assignment(). This isn't a great method of verifying the consumer assignment.
