I was also surprised by the discussion of stronger isolation in the paper. The paper claims snapshot isolation hasn’t been implemented in distributed systems yet, because it strictly requires a centralized global counter to serialize transactions. This is flagged as a fatal bottleneck and single point of failure.
The move came as a surprise to David Juurlink, professor of medicine and pediatrics at the University of Toronto, who has spent over a decade looking into the claim that infants can receive a meaningful or even lethal dose of opioids via breast milk when their mothers take acetaminophen with codeine. The first such case, published in the Lancet in 2006 by pharmacologist Gideon Koren, was the centerpiece of the New Yorker article. (The Lancet case report now bears an expression of concern.)
