Subject memory overhead of vector clocks vs timestamps and running *without* either to save memory?
Date Sat, 20 Aug 2011 00:41:30 GMT
I have a few questions which I can't seem to find answers to...

I know that the memory overhead of timestamps is 8 bytes per row/column.
  What is the memory overhead of vector clocks?

Is it possible (at least in theory) to run without timestamps on your
values?  I'm fine with last writer wins semantics and the memory overhead
here seems very high.

I understand that the timestamps might also be for repartitioning which adds
complexity.

Thanks!
