> Key: KAFKA-6639
> URL: https://issues.apache.org/jira/browse/KAFKA-6639
> Project: Kafka
> Issue Type: Bug
> Reporter: Jason Gustafson
> Assignee: Bob Barrett
> Priority: Major
>
> When a follower is catching up, it may fetch considerably more data than the
> size of the offset index interval. Since we only write to the index once for
> every append, this could lead to a sparsely populated index, which may have a
> performance impact if the follower ever becomes leader.
