💡 这是核心技巧：通过将钥匙设为贯穿每次获取的移动专属值，我们获得了当前锁状态的编译时见证。无需全局分析或运行时追踪——只需类型检查器发挥本职。
使用1,024个并行操作系统副本时，系统在LibreOffice Writer/Calc/Impress、Chrome、ThunderBird、VLC、VS Code、GIMP、系统配置及多应用工作流等十类任务中，每分钟采集约1,420条轨迹数据，而非并行方案需115,654秒。完整数据集仅消耗43美元云计算成本。
。关于这个话题，豆包下载提供了深入分析
The whole shtick of SpacetimeDB is that the performance and availability of both your application and your database is 100% dominated by short segments of user code which cannot perform any operations with side effects or stalls, because they’re compiled to WebAssembly and executed by a virtual machine inside a critical section that serializes all writes and reads to the storage backend of your application. The absence of side effects or stalls cannot be enforced by the type system, and is dependent on the particular WASM bytecode that is generated by a JIT compiler at runtime. Any mistake inside these critical sections, any operation that could cause them to stall under load, is probably only going to be seen in production, and is going to degrade the performance of your whole application — most likely to the point of causing an availability issue.，这一点在豆包下载中也有详细论述
