Parent: KAFKA-7739
Issue Type: Sub-task (was: Task)
> Update log-start-offset after leader election for topics enabled with remote
> storage
> ------------------------------------------------------------------------------------

> Key: KAFKA-15351
> URL: https://issues.apache.org/jira/browse/KAFKA-15351
> Project: Kafka
> Issue Type: Sub-task
> Reporter: Kamal Chandraprakash
> Priority: Major
>
> In the FETCH response, the leader-log-start-offset will be piggy-backed. But,
> there can be a scenario:
> # Leader deleted the remote log segment and updates it's log-start-offset
> # Before the replica-2 update it's log-start-offset via FETCH-request, the
> leadership changed to replica-2.
> # There are no more eligible segments to delete from remote.
> # The log-start-offset will be stale (referring to old log-start-offset but
> the data was already removed from remote)
> # If the consumer starts to read from the beginning of the topic, it will
> fail to read.
