Feature better be implemented on application side, thus closing this ticket.
> Introduce LocalLease for followers
> ----------------------------------
>
> Key: RATIS-2341
> URL: https://issues.apache.org/jira/browse/RATIS-2341
> Project: Ratis
> Issue Type: Improvement
> Reporter: Janus Chow
> Priority: Major
> Time Spent: 5.5h
> Remaining Estimate: 0h
>
> The current logic of ReadIndex limits the performance of FollowerRead.
>
> In production, the vast majority of requests are for old data, so running the
> readIndex logic for every request becomes somewhat wasteful.
> This ticket is to introduce LocalLease for followers, so that followers can
> decide if it's catched up with Leader, and application can reasonably make
> use of this information.
