Mike Percy updated KUDU-489:
----------------------------
Parent: KUDU-433
> Implement a mechanism to make consensus terms serializable and persistent
> -------------------------------------------------------------------------
>
> Key: KUDU-489
> URL: https://issues.apache.org/jira/browse/KUDU-489
> Project: Kudu
> Issue Type: Sub-task
> Components: consensus
> Affects Versions: M4
> Reporter: David Alves
> Assignee: Mike Percy
> Priority: Critical
> Original Estimate: 16h
> Remaining Estimate: 16h
>
> Consensus terms must be serializable. That is
> a majority of replicas must agree, across reboots, who was voted/elected
> leader, if anyone, for all terms.
> To achieve this we need some kind of consensus metadata persistence and we
> need a serialization mechanism that implements this.
> The raft paper/logcabin impl/paxos in general should be a reference in this
> regard
