Matthias J. Sax reassigned KAFKA-20877:
---------------------------------------
Assignee: Matthias J. Sax
> Streams task-level restore-rate and update-rate incorrect
> ---------------------------------------------------------
>
> Key: KAFKA-20877
> URL: https://issues.apache.org/jira/browse/KAFKA-20877
> Project: Kafka
> Issue Type: Bug
> Components: streams
> Affects Versions: 3.5.0
> Reporter: Matthias J. Sax
> Assignee: Matthias J. Sax
> Priority: Major
>
> The task-level metrics restore-rate/restore-total (active tasks) and
> update-rate/update-total (standby tasks) are meant to report how many
> changelog records were restored or updated. update-rate is documented as "The
> average number of records updated per second".
> However, the rate-metric is incorrectly captured. It counts how many times
> the sensor was recorded and discards the value (number of records restored),
> so it incorrectly reports restore/update batches per second.
> Introduced via KAFKA-10199 which added these metrics.
