"The case for determinism in database systems" paper (which described the technology that became Calvin) was written in VLDB 2010. At least one VoltDB developer told me that command logging came from a talk we gave about this paper to your team.

I think they happened independently, but it's long enough ago that I might not recall if I or Ning had inspiration from somewhere.

If you heard it from Ning or myself then it's probably what happened.

Yes Ariel, it was you who told me this! But I agree with jhugg that it was an obvious choice based on the VoltDB architecture.

I think that logical logging was an obvious choice given VoltDB architecture. It's totally possible there was a talk that was involved for somebody though.

That said, we <3 determinism at VoltDB and rely on it to achieve what we achieve.
