Reviewer: lenn0x (was: chrisg)
> Allow the client request scheduler to throw Timeouts
> ----------------------------------------------------
>
> Key: CASSANDRA-3079
> URL: https://issues.apache.org/jira/browse/CASSANDRA-3079
> Project: Cassandra
> Issue Type: Improvement
> Components: API
> Reporter: Stu Hood
> Assignee: Stu Hood
> Priority: Minor
> Fix For: 1.0
>
>
> The RoundRobinScheduler prioritizes threads by allowing them to queue on a
> SynchronousQueue per scheduling bucket. These queues currently do not use
> timeouts, and we observed a cascading case where client retries caused the
> scheduler queues to fill such that latency was way above the client timeout.
> Allowing the IRequestScheduler.queue method to throw a (per-call
> configurable) timeout, we can avoid this cascading.
