    Sink that is aware of the committable offset from a Consumer.

    Sink that is aware of the committable offset from a Consumer. It will commit the consumer offset when the message has been published successfully to the topic.

    Note that there is always a risk that something fails after publishing but before committing, so it is "at-least once delivery" semantics.
