I think this could be a worthwhile comparison if tested on a platform where the in-memory store is as safe as traditional hard-disk storage, say a machine with some form of static (non-volatile) RAM for main memory.
Thus the question would be, does the performance advantage of VoltDB's approach outweigh the penalty of static RAM performance?
- dedward 16y agoWhat would that static ram device be, and how would you scale it out?
- jasongullickson 16y agoI'm not sure that such a device exists.

According to wikipedia they already created such a prototype - http://en.wikipedia.org/wiki/Memristor#Potential_applications http://en.wikipedia.org/wiki/Memristor#Potential_application....
- jasongullickson 16y agoI should have been more specific. I'm familiar with all sorts of non-volatile memory (flash, etc.) but I'm not aware of any modern computer that uses it as main memory (that is, directly addressable RAM as opposed to connected via a storage bus). I think the last thing I used that would qualify as such was the Apple Newton.
