Hi. What is the idiomatic / correct way to know that a restarted broker in an existing Kafka cluster has caught up to all the leaders for the partitions it hosts? Is there a specific JMX metric published either by the leader / follower that we can monitor?
Ideally, the metric would have the following characteristics: *Metric:* IsInSync=Yes/No *Dimensions:* LeaderId = L, FollowerId = F, Topic = T, Partition = P If not, do you think this would be useful?
