Perplexity 详细介绍了其 SPACE 沙盒系统，该系统每天管理数百万次执行，错误率低于0.0002%。该系统使用加密身份来确保请求被正确路由到活动执行，即使在沙盒暂停、恢复或跨机器迁移时也是如此。这种机制可以防止过时的路由将有效请求发送到旧的、不活动的执行并返回过时的数据。 AI

Terminals and file watches can outlive their opening requests. Once a receiver installs the new execution identity, SPACE stops the old streams. Eligible operations can reconnect once, passing the identity checks again. Read the article: https://t.co/jH6TX2cgI9 https://t.co/BQWA…
Each request carries short-lived, signed proof of which execution may handle it and what access is allowed. The receiving worker checks that identity against its own runtime record and rejects mismatches before forwarding. https://t.co/H6fWrAmb5p
When a sandbox resumes on another machine, it keeps its sandbox ID but starts a new execution. A stale route can send a valid request to the older execution and return old data. Checking the sandbox ID alone won’t catch the difference.
Our sandbox, SPACE, handles millions of executions a day with an error rate below 0.0002%. We’re sharing how it uses cryptographic identity to keep requests tied to the right execution as sandboxes pause, resume, and move. Read more: https://t.co/jH6TX2cgI9
