论文摘要
许多现代应用程序会产生大量的数据系列流,并将其维护在索引中,以便能够通过最近的邻居搜索来探索它们。但是,现有的数据系列索引操作很昂贵,因为它们会发布许多随机的I/OS存储。为了解决这个问题,我们最近提出了椰子,这是一种基于新的可排序格式的数据系列的新基础架构。这样,椰子能够利用首次依靠排序的最新索引技术来使用快速顺序I/OS构建,维护和查询数据系列索引。在此演示中,我们提出了椰子棕榈,这是一种新的探索工具,允许从椰子基础设施内部进行交互性地结合不同的索引技术,从而无缝地探索来自各个科学领域的数据系列。我们强调了椰子开放的丰富索引设计选择,并提出了一种新的推荐工具,该工具允许用户智能地导航静态和流数据探索方案。
Many modern applications produce massive streams of data series and maintain them in indexes to be able to explore them through nearest neighbor search. Existing data series indexes, however, are expensive to operate as they issue many random I/Os to storage. To address this problem, we recently proposed Coconut, a new infrastructure that organizes data series based on a new sortable format. In this way, Coconut is able to leverage state-of-the-art indexing techniques that rely on sorting for the first time to build, maintain and query data series indexes using fast sequential I/Os. In this demonstration, we present Coconut Palm, a new exploration tool that allows to interactively combine different indexing techniques from within the Coconut infrastructure and to thereby seamlessly explore data series from across various scientific domains. We highlight the rich indexing design choices that Coconut opens up, and we present a new recommender tool that allows users to intelligently navigate them for both static and streaming data exploration scenarios.
