Stanislav Kozlovski commented on KAFKA-15147:
---------------------------------------------
[~divijvaidya] given that there is no kip, is it realistic to still target AK
3.7? Perhaps we should remove the Fix Version until we have confidence in the
release, otherwise it just ends up getting bumped each release (as we've seen
in many other unrelated jiras)
> Measure pending and outstanding Remote Segment operations
> ---------------------------------------------------------
>
> Key: KAFKA-15147
> URL: https://issues.apache.org/jira/browse/KAFKA-15147
> Project: Kafka
> Issue Type: Improvement
> Components: core
> Reporter: Jorge Esteban Quilcate Otoya
> Assignee: Divij Vaidya
> Priority: Major
> Labels: tiered-storage
> Fix For: 3.7.0
>
>
> Remote Log Segment operations (copy/delete) are executed by the Remote
> Storage Manager, and recorded by Remote Log Metadata Manager (e.g. default
> TopicBasedRLMM writes to the internal Kafka topic state changes on remote log
> segments).
> As executions run, fail, and retry; it will be important to know how many
> operations are pending and outstanding over time to alert operators.
> Pending operations are not enough to alert, as values can oscillate closer to
> zero. An additional condition needs to apply (running time > threshold) to
> consider an operation outstanding.
> Proposal:
> RemoteLogManager could be extended with 2 concurrent maps
> (pendingSegmentCopies, pendingSegmentDeletes) `Map[Uuid, Long]` to measure
> segmentId time when operation started, and based on this expose 2 metrics per
> operation:
> * pendingSegmentCopies: gauge of pendingSegmentCopies map
> * outstandingSegmentCopies: loop over pending ops, and if now - startedTime
> > timeout, then outstanding++ (maybe on debug level?)
> Is this a valuable metric to add to Tiered Storage? or better to solve on a
> custom RLMM implementation?
> Also, does it require a KIP?
> Thanks!
