--------------------------------------
Summary: Follower may have sparse index if catching up
Key: KAFKA-6639
URL: https://issues.apache.org/jira/browse/KAFKA-6639
Project: Kafka
Issue Type: Bug
Reporter: Jason Gustafson
Assignee: Dhruvil Shah
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.
