The most merciful thing in the world, I think, is the inability of the human mind to correlate all its contents. We live on a placid island of ignorance in the midst of black seas of infinity, and it was not meant that we should voyage far. The sciences, each straining in its own direction, have hitherto harmed us little; but some day the piecing together of dissociated knowledge will open up such terrifying vistas of reality, and of our frightful position therein, that we shall either go mad from the revelation or flee from the deadly light into the peace and safety of a new dark age.
The commit protocol in the paper actually starts simple: clients send log records straight to Pending Update (PU) queues. But the problem with this naive direct-write approach is that if the client crashes mid-commit, only some records might make it to the queue, and this breaks atomicity. To fix this issue, the paper proposes an Atomicity protocol: clients first dump all logs plus a final “commit” token into a private ATOMIC queue, then push everything to the public PU queues. This guarantees all-or-nothing transactions, but it’s pricey, since every extra SQS message adds up. At $2.90 per 1,000 transactions, it’s almost twenty times the $0.15 of the naive direct-write approach. So here, consistency comes at a literal monetary cost!
