Jie Yu updated MESOS-7973:
--------------------------
Target Version/s: 1.5.0
> Non-leading VOTING replica catch-up
> -----------------------------------
>
> Key: MESOS-7973
> URL: https://issues.apache.org/jira/browse/MESOS-7973
> Project: Mesos
> Issue Type: Improvement
> Components: replicated log
> Reporter: Ilya Pronin
> Assignee: Ilya Pronin
>
> Currently it is not possible to perform consistent reads from non-leading
> replicas due to the fact that if a non-leading replica is partitioned it may
> miss some log positions and will not make any attempt to “fill” those holes.
> If a non-leading replica could catch-up missing log positions it would be
> able to serve eventually consistent reads to the framework. This would make
> it possible to do additional work on non-leading framework replicas (e.g.
> offload some reading from a leader to standbys or reduce failover time by
> keeping in-memory storage represented by the log “hot”).
> Design doc:
