PLANET: Query Plan Visualizer for Shipping Policies against Single SPARQL Endpoints.

Shipping policies allow for deciding whether a query should be executed at the server, the client or distributed among these two. Given the limitations of public SPARQL endpoints, selecting appropriate shipping plans is crucial for successful query executions without harming the endpoint performance. We present PLANET, a query plan visualizer for shipping strategies against a single SPARQL endpoint. We demonstrate the performance of the shipping policies followed by existing SPARQL query engines. Attendees will observe the effects of executing different shipping plans against a given endpoint.
