Dear nprofile1qy2hwumn8ghj7un9d3shjtnddaehgu3wwp6kyqpqvudwkxsxvh5yv6sws50rgd52v6tz3z43pzq7n0gwzczjkvpq3n3qkuszvf (nprofile…szvf), we are very happy to see that you are deploying a QLever-based SPARQL endpoint. Would you probably mind to increase your cache size as this simple 2-hop query doesn't work:
SELECT ?p ?o ?pp ?oo WHERE {
<https://dblp.org/rec/books/acm/19/X19>; ?p ?o .
OPTIONAL { ?o ?pp ?oo . }
}
https://sparql.dblp.org/n9kCi4
Thank you very much!! :)
