> Key: CASSANDRA-12626
> URL: https://issues.apache.org/jira/browse/CASSANDRA-12626
> Project: Cassandra
> Issue Type: Bug
> Components: Observability
> Reporter: Christopher Batey
> Assignee: Christopher Batey
> Priority: Minor
> Fix For: 3.x
>
>
> I was surprised how little contention was being reported and looking at the
> code we miss out reporting contention when there is a timeout at the prepare
> phase.
> If this {{StorageProxy.beginAndRepairPaxos}} throws then the contentions
> count isn't added to the histogram.
