What is it about?
Federation engines allows to query multiple knowledge graphs with a single SPARQL query. However, they are currently limited to dozens of SPARQL endpoint. FedUp proposes a new kind of query plan allowing to scale up to hundreds of SPARQL endpoints.

Why is it important?
Improving the scalability of federation engines allows to query a large decentralized semantic web.
Perspectives
We demonstrated that we can scale to hundreds of SPARQL endpoints, but we think it should scale to thousands of SPARQL endpoints.
