Looking back, we find this claim outdated. Global counters aren’t a bottleneck for Snapshot Isolation: Amazon Aurora stamps transactions with a Global Log Sequence Number (GLSN) via a primary writer, but still scales (vertically) cleanly without slowing disaggregated storage. More importantly, modern distributed database systems implement snapshot isolation, using loosely synchronized physical clocks (and hybrid logical clocks) to give global ordering with no centralized counter at all. Thank God for synchronized clocks!
