> Most are optional comments but the blocking comments before we merge are the once related to removal of metrics when topic is deleted. I would assume that removal needs to occur from newly introduced `topicMetricValues` map in `BrokerTopicAggregateMetric`? @divijvaidya , thanks for your review. The metrics removal of topic deletion will be triggered in rlm#stopPartitions, and then `removeRemoteTopicPartitionMetrics` will be invoked. The removal for the "allTopic" metric is done via removing the partition value from the specific topic, ex: ``` # We first remove the partition value from this topic brokerTopicStats.topicStats(topicIdPartition.topic()).removeRemoteCopyLagBytes(partition); # Later, we update the topic value in the "allTopic" metric. So, once all partitions are removed, the value of the specific topic will be 0. brokerTopicStats.allTopicsStats().recordRemoteCopyLagBytes(topic, topicMetrics.remoteCopyLagBytes()); ``` I'll address your comments this weekend or next week.
