Dynamic Data Exchange in Distributed RDF Stores.
IEEE Transactions on Knowledge and Data Engineering(2018)
摘要
When RDF datasets become too large to be managed by centralised systems, they are often distributed in a cluster of shared-nothing servers, and queries are answered using a distributed join algorithm. Although such solutions have been extensively studied in relational and RDF databases, we argue that existing approaches exhibit two drawbacks. First, they usually decide statically(i.e., at query co...
