> In Kafka Streams we record throughput / latency metrics on EACH processing record, causing
a lot of recording overhead. Instead, we should consider statistically sampling messages flowing
through to measures latency and throughput.
> This is based on our observations from KAFKA-3769 and KAFKA-3811.
