> In the old producer we have droppedMessageRate that allows user to monitor the number of messages dropped when buffer is full and block on buffer full is set to false. This metric is useful in operation. However, in the new producer we don't have this a metric.
> The "errors" sensor in new-producers measures per-record error that is not limited to those caused by BufferExhaustedException. Thus it is not good enough.
