> Paxos repair blocks response thread
> -----------------------------------
>
> Key: CASSANDRA-20983
> URL: https://issues.apache.org/jira/browse/CASSANDRA-20983
> Project: Apache Cassandra
> Issue Type: Bug
> Components: Consistency/Coordination
> Reporter: Blake Eggleston
> Assignee: Blake Eggleston
> Priority: Normal
>
> CASSANDRA-20469 prevented paxos repairs from preempting in progress paxos
> transactions by holding repairs until after they would have timed out.
> However, it added a sleep that’s often called in the request response stage,
> and with the PaxosCleanupLocalCoordinator lock held. This patch adjusts this
> by putting a delayed repair into a delayed queue, and scheduling a wakeup
> task for after the timeout expires.
