Data Su ciency for Queries on Cache
In distributed computing environments, replication of data provides improved availability, isolation between workloads with di erent characteristics, and improved performance through local access to data. The \real data" is server resident and by \local data" we refer to cached client data. We examine which data should be cached on behalf of a cached query. The minimum requirement for cached da...

متن کاملEfficient Cache Answerability for XPath Queries
The problem of cache answerability has traditionally been studied over conjunctive queries performed on top of a relational database system. However, with the proliferation of semistructured data and, in particular, of XML as the de facto standard for information interchange on the Internet, most of the assumptions and methods used for traditional systems – and cache answerability is no excepti...
متن کاملCache Pattern with Multi-Queries
82 Abstract—This article proposes a cache pattern with multiqueries and describes the multi-query optimization with scheduling, caching and pipelining A set of cache patterns is derived from a set of class of multiqueries that are loaded into the cache. Each cache pattern represents a unique equivalence class in the set of patterns. The multi-query optimization with scheduling, caching and pipe...
متن کاملCache-Sensitive Skip List: Efficient Range Queries on Modern CPUs
Due to ever falling prices and advancements in chip technologies, many of today’s databases can be entirely kept in main memory. However, reusing existing disk-based index structures for managing data in memory leads to suboptimal performance due to inefficient cache usage and negligence of the capabilities of modern CPUs. Accordingly, a number of main-memory optimized index structures have bee...
