Description

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.
