论文摘要
我们使用校准数据管道的层次结构来描述一种基于策略的方法来扩展共享数据服务,以自动化数据流的持续集成。虽然没有独特的解决方案解决时间顺序问题,但我们展示了如何通过通过将局部交易以便时间分辨率来使用可靠的“最新版本”语义来复制可靠的“最新版本”语义。因此,我们从所有碎片上的一个碎片上建立了一个不变的全局排序,并具有控制的可伸缩性。这形成了版本的坐标系(或版本的命名空间),具有一致的语义和自我保护速率限制版本,类似于发布内容交付网络(CDN)或名称数据网络(NDN)方案的订阅方案。
We describe a policy-based approach to the scaling of shared data services, using a hierarchy of calibrated data pipelines to automate the continuous integration of data flows. While there is no unique solution to the problem of time order, we show how to use a fair interleaving to reproduce reliable `latest version' semantics in a controlled way, by trading locality for temporal resolution. We thus establish an invariant global ordering from a spanning tree over all shards, with controlled scalability. This forms a versioned coordinate system (or versioned namespace) with consistent semantics and self-protecting rate-limited versioning, analogous to publish-subscribe addressing schemes for Content Delivery Network (CDN) or Name Data Networking (NDN) schemes.
