[jira] [Comment Edited] (KAFKA-9543) Consumer offset reset after
new segment rolling
[ https://issues.apache.org/jira/browse/KAFKA-9543?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17039336#comment-17039336 ]

Yes it is consumer lag (every color represents different partition). As you can see before update there was practically none of it (it can be easily deduced when upgrade took place ;)). I will try to reproduce it and let you know how it went.

> All resets are perfectly correlated to rolling new segments at the broker - segment is rolled first, then, couple of ms later, reset on the consumer occurs. Attached is grafana graph with consumer lag per partition. All sudden spikes in lag are offset resets due to this bug.
