Kurzfassung
Recent studies reveal that publicly available SPARQL endpoints exhibit
significant limitations in supporting real-world applications. In order for this
querying infrastructure to reach its full potential, more flexible client-server architectures
capable of deciding appropriate shipping plans are needed. Shipping
plans indicate how the execution of query operators is distributed between the
client and the server. We propose SHEPHERD, a SPARQL client-server query
processor tailored to reduce SPARQL endpoint workload and generate shipping
plans where costly operators are placed at the client site. We evaluated SHEPHERD
on a variety of public SPARQL endpoints and SPARQL queries. Experimental
results suggest that SHEPHERD can enhance endpoint performance while
shifting workload from the endpoint to the client.
