多重宇宙数据库透明地为每个应用程序用户提供灵活、动态和独立的共享数据视图。整个数据库的转换视图仅包含集中式且易于审计的隐私策略所允许的信息。通过在数据库中强制执行一次隐私策略,Multiverse数据库减轻了程序员的负担,并消除了许多暴露敏感数据的前端错误。如果在读取时动态应用Multiverse数据库的每用户转换,则会带来昂贵的查询风险,或者如果数据库主动实现符合策略的视图,则会产生不切实际的存储需求。我们提出了一个有效的设计的基础上,跨“宇宙”,结合了全球性的,共享的计算和缓存状态与个人,每个用户的处理和状态的联合调度。这种设计支持任意SQL查询和复杂策略,不会对读查询造成性能开销。我们的早期原型在一台服务器上支持数千个平行宇宙。
A multiverse database transparently presents each application user with a flexible, dynamic, and independent view of shared data. This transformed view of the entire database contains only information allowed by a centralized and easily-auditable privacy policy. By enforcing the privacy policy once, in the database, multiverse databases reduce programmer burden and eliminate many frontend bugs that expose sensitive data.Multiverse databases' per-user transformations risk expensive queries if applied dynamically on reads, or impractical storage requirements if the database proactively materializes policy-compliant views. We propose an efficient design based on a joint dataflow across "universes" that combines global, shared computation and cached state with individual, per-user processing and state. This design, which supports arbitrary SQL queries and complex policies, imposes no performance overhead on read queries. Our early prototype supports thousands of parallel universes on a single server.
