-----------------------------
Summary: Add an option to replica from the largest offset during
unclean leader election
Key: KAFKA-763
URL: https://issues.apache.org/jira/browse/KAFKA-763
Project: Kafka
Issue Type: Improvement
Components: core
Affects Versions: 0.8
Reporter: Jun Rao
Assignee: Jun Rao
Priority: Blocker
If there is an unclean leader election, a follower may have an offset out of
the range of the leader. Currently, the follower will delete all its data and
refetch from the smallest offset of the leader. It would be useful to add an
option to let the follower refetch from the largest offset of the leader since
refetching from the smallest offset may take some time.
