------------------------------------
Summary: 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
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.
