Ismael Juma commented on KAFKA-6040: ------------------------------------ Retention is done on a partition, not topic, so the broker doesn't need to maintain a topic size at the moment. The partition size is exposed via a Log size metric > Expose topic size for monitoring > -------------------------------- > > Key: KAFKA-6040 > URL: https://issues.apache.org/jira/browse/KAFKA-6040 > Project: Kafka > Issue Type: New Feature > Reporter: Michael Andre Pearce > > Currently it seems there is no monitoring endpoint of topic size, even though > the cluster must calculate such estimation to maintain retention.size > This is useful operationally to get understanding of actual topic usages, > based on what the broker believes. > As interim it seems some scripts exist to get this, but it would be ideal to > get the value the broker believes/calculates. > https://gist.github.com/kapkaev/ef633348dbecfedc0166 -- This message was sent by Atlassian JIRA (v6.4.14#64029)
