Jie Yu updated MESOS-3572:
--------------------------
Component/s: replicated log
> Faster catchup protocol for "learned" replicated log entries
> ------------------------------------------------------------
>
> Key: MESOS-3572
> URL: https://issues.apache.org/jira/browse/MESOS-3572
> Project: Mesos
> Issue Type: Improvement
> Components: replicated log
> Reporter: Neil Conway
>
> Right now, the catchup protocol does a full Paxos round for every log entry
> missing from a recovering replica. This should be unnecessary for "learned"
> log entries, because there is no uncertainty about the status of such log
> entries. We'll probably only need to do a full Paxos round for entries near
> the tail of the log.
> To motivate changing this, it would be good to first measure the performance
> of the catchup protocol to understand if/when performance improvements would
> be useful. There's also [MESOS-770], which mentions the idea of doing catchup
> in parallel.
