@[~ChrisEgerton] Hello, if you have time, please take a look at this issue.
> Incorrect replication Latency may be calculated when the timestamp of the
> record is of type CREATE_TIME

> Key: KAFKA-15068
> URL: https://issues.apache.org/jira/browse/KAFKA-15068
> Project: Kafka
> Issue Type: Improvement
> Components: mirrormaker
> Reporter: hudeqi
> Assignee: hudeqi
> Priority: Major
>
> When MM2 is used to replicate topics between Kafka clusters, if the timestamp
> of the record of the source cluster is of type CREATE_TIME, then the value of
> timestamp may not be the actual "creation time (that is, append time)", for
> example, the value of timestamp is less than the current time for a long time
> (this is determined by the producer, and often occurs in the online
> environment), at this time, the calculated replication latency will be too
> large.
> I understand that replication latency reflects the performance of replication
> and should not be affected by this abnormal situation.
