I said in my post: "influenced the design of several modern “NewSQL” systems" --- I'm not aware of other production implementations of Calvin. But VoltDB's command logging feature came directly from Calvin. So basically I had in mind FaunaDB and VoltDB when I wrote that sentence. Neither is an exact version of Calvin, but FaunaDB is closer to Calvin than VoltDB. Obviously, the Calvin paper has been cited many hundreds of times, so many of its ideas have made it into other systems as well.
"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 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.
My brief summary comparison. VoltDB is a bit less general in some key ways. It tends to have the same performance no matter how much contention there is, which is rare. It's also getting pretty mature, with lots of integrations and hard corners sanded off.
It also typically has much lower latency than these systems, both theoretically and practically.
