Abstract
In general, techniques are described for an RDF (Resource Description Framework) database system which can scale to huge size for realistic data sets of practical interest. In some examples, a database system includes a Resource Description Framework (RDF) database that stores a plurality of data chunks to one or more storage drives, wherein each of the plurality of data chunks includes a plurality of triples of the RDF database. The database system also includes a working memory, a query interface that receives a query for the RDF database, a SPARQL engine that identifies a subset of the data chunks relevant to the query, and an index interface that includes one or more bulk loaders that load the subset of the data chunks to the working memory. The SPARQL engine executes the query only against triples included within the loaded subset of the data chunks to obtain a query result.
