> Sampling on throughput / latency metrics recording in Streams
> -------------------------------------------------------------
>
> Key: KAFKA-3826
> URL: https://issues.apache.org/jira/browse/KAFKA-3826
> Project: Kafka
> Issue Type: Bug
> Components: streams
> Reporter: Guozhang Wang
> Labels: architecture, performance
>
> 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.
