Did you ever read Pat Helland's article, "Life Beyond Distributed Transactions: An apostate’s opinion" https://dl.acm.org/doi/10.1145/3012426.3025012? "This article explores and names some of the practical approaches used in the implementation of large-scale mission-critical applications in a world that rejects distributed transactions."
Admittedly I live in a world where big distributed transactions are a given and work fine and sql speeds us up not slows us down. I’m guessing sql and acid scaled after all?
Yes and no. Distributed transactions and two-phase commit have been superseded by things like Paxos and Raft, with a variety of consistency models, so the implementation is drastically different.
