> Project: Apache Cassandra
> Issue Type: Improvement
> Components: Accord
> Reporter: Benedict Elliott Smith
> Priority: Normal

> Improve Tail Latency
> - Introduce fast quorum medium path
> - Mitigate convoy effect:
> - ExecuteTxnBacklog v1 can execute single key transaction backlogs and
> disseminate the result
> - Direct local execution possible for single key transactions
> - Use shardAppliedBefore instead of gcBefore to cleanup CFK faster
> Also Improve:
> - Introduce distributed tracing
> - Combine RejectBefore and MaxConflicts
> - Self-addressed messages are delivered directly
> - ProtocolModifiers mostly final
> Also Fix:
> - BTree.XUpdater.reset()
> - computeUnsyncedEpoch was incorrect
> - Remove reject flag from MaxConflicts.Entry
> - Requeue waiting state polling mode requeues from callbacks to avoid
> crowding out other work
