Aleksey Yeschenko updated CASSANDRA-8520:
-----------------------------------------
Assignee: (was: Aleksey Yeschenko)
> Prototype thread per core
> -------------------------
>
> Key: CASSANDRA-8520
> URL: https://issues.apache.org/jira/browse/CASSANDRA-8520
> Project: Cassandra
> Issue Type: Task
> Reporter: Jonathan Ellis
> Labels: performance
> Fix For: 3.x
>
>
> Let's prototype the best possible scenario for how well we can perform with a
> thread per core design by simplifying everything we can. For instance,
> - No HH, no RR, no replication at all
> - No MessagingService
> - No compaction (so test a workload w/o overwrites)
> - No repair
> - Just local writes and reads
> If we can't get a big win (say at least 2x) with these simplifications then I
> think we can say that it's not worth it.
> If we can get a big win, then we can either refine the prototype to make it
> more realistic or start working on it in earnest.
