This is impressive, but won't have huge impact, IMO.

Way back in 2015, MySQL Cluster (NDB Cluster engine) benchmarked 200m transactions/second on commodity hardware [1]. It was read-committed transactions, not snapshot isolation, but still impressive. NDB (or RonDB, the new DB by its author) uses a non-blocking 2-phase commit protocol (failed transaction coordinators are failed over) and is even open-source. Still, it hasn't had a big impact outside of the Telecom and real-time gaming worlds.
