Joel Koshy commented on KAFKA-604: ---------------------------------- The rebased patch does not really comment on/address the concern in the original review - i.e., it breaks a relatively clean and convenient syntax in the common case (of updating a single timer) to support updates to multiple timers. It's obviously not a particularly major issue, but a rung higher than say, a debate over whitespace/coding style. My only point is that we should try and avoid making a change that goes from a nice syntax to a rather inconvenient syntax. For that reason, I'm more in favor of the change to KafkaTimer in KAFKA-646. That said, how about the following: both these patches need multiple timer updates to update an aggregate timer as well as a specific timer - i.e., up to this point we don't really have a use case for updating more than two timers simultaneously. So we can accomplish this case with the following: aggregatekafkatimer.time { specifickafkatimer.time { <code block> } } and avoid any change to KafkaTimer. Does that seem reasonable to you guys? > Add missing metrics in 0.8 > -------------------------- > > Key: KAFKA-604 > URL: https://issues.apache.org/jira/browse/KAFKA-604 > Project: Kafka > Issue Type: Bug > Components: core > Affects Versions: 0.8 > Reporter: Jun Rao > Attachments: kafka_604_v1.patch, kafka_604_v2.patch, kafka_604_v3.diff > > Original Estimate: 24h > Remaining Estimate: 24h > > It would be good if we add the following metrics: > Producer: droppedMessageRate per topic > ReplicaManager: partition count on the broker > FileMessageSet: logFlushTimer per log (i.e., partition). Also, logFlushTime > should probably be moved to LogSegment since the flush now includes index > flush time. -- This message is automatically generated by JIRA.
