Abstract

The embodiment of the invention provides a telescopic distributed resource description framework (RDF) data storage method and device. The method provided by the invention comprises the following steps: distributing all the RDF data into memory of at least two storage nodes to be stored; backing up data in the memory of each first storage node into a persistent memory of a second storage node, wherein the first storage node and the second storage node are any one storage node of at least two storage nodes, and the second storage node is adjacent to the first storage node. By adopting the telescopic distributed RDF data storage method and device which are provided by the embodiment of the invention, data storage and query efficiency can be improved, and data can be rapidly restored locally from the adjacent storage node of the storage node when one storage node is failure, so that a data storage and query service is continuously provided.

Description

technical field [0001] The present invention relates to the computer field, in particular to a scalable and distributed resource description framework data storage method and device. Background technique [0002] The Semantic Web is to add semantics (Meta Data) that can be understood by machines through documents on the World Wide Web, so that the entire Internet becomes a general information exchange medium. The Resource Description Framework (RDF) is a World Wide Web Consortium (W3C) standard for describing web resources, and is used to express metadata about Internet web resources, such as the title, author, Modification date, content and copyright information, etc. Research on the Semantic Web based on RDF data has always been a research hotspot in the scientific community. How to store and query massive RDF data with high performance and easy scalability has become an urgent problem to be solved. [0003] In the prior art, for massive RDF data, the academic community...
