Isolation guaranteesIn order to prioritize extreme availability, the system throws traditional isolation guarantees out the window. The paper says ANSI SQL-style isolation and strict consistency cannot survive at scale in this architecture. The atomicity protocol prevents dirty reads by ensuring only fully committed logs leave a client’s private queue, but commit-time read-write and write-write conflicts are ignored entirely! If two clients hit the same record, the last-writer wins. So lost updates are common. To make this usable, the authors push consistency up to the client. For ensuring monotonic reads, each client tracks the highest commit timestamp it has seen, and if it sees any older version from S3 it rejects it and rereads. For monotonic writes, the client stamps version counters on log records and page headers. Checkpoints sort logs and defer any out-of-order SQS messages so each client’s writes stay in order.

当行业进入衰退期，这种关系的复杂性会更突出：客人减少，竞争加剧，成本上升，促销更频繁，“谁能抢到生意”变成生存逻辑。与此同时，年轻一代对“夜总会”这个词本身就有距离感，更倾向于用“PR”等更体面的说法来重新包装工作内容；行业对人的吸引力下降，也意味着女性从业者的处境更不稳定。
