> Support S3 secure follower read
> --------------------------------
>
> Key: HDDS-16670
> URL: https://issues.apache.org/jira/browse/HDDS-16670
> Project: Apache Ozone
> Issue Type: Sub-task
> Reporter: Ivan Andika
> Assignee: Bolin Lin
> Priority: Major
>
> At the current state, secure S3 reads cannot use the follower read feature.
> S3SecurityUtil#validateS3Credential requires that the current OM is a leader.
> The documented reason is that follower can be arbitrarily behind the leader
> and therefore might not see the token or the revocation. Due to this reason,
> currently OM follower read is not supported for secure S3 reads.
> We can think on how to support it. For follower linearizable read, we can
> probably allow it since the ReadIndex mechanism ensure linearizability and
> the follower will not return until it's caught up to the ReadIndex. However,
> for local lease, it might be a bit tricky since it doesn't guarantee
> linearizability.
