It starts up when dropped in, but the first example in the docs using wikidata fails with a timeout. It looks like a different bug, either in the example, or in the rewriting, where the ?s values aren't injected. If the VALUES clause are moved into the service, there is a cache result. The example from the docs: ``` PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#> PREFIX wd: <http://www.wikidata.org/entity/> SELECT ?s ?l { # The ids below correspond in order to: Apache Jena, Semantic Web, RDF, SPARQL, Andy Seaborne VALUES ?s { wd:Q1686799 wd:Q54837 wd:Q54872 wd:Q54871 wd:Q108379795 } SERVICE <cache:loop:bulk+5:https://query.wikidata.org/sparql> { SELECT ?l { ?s rdfs:label ?l FILTER(langMatches(lang(?l), 'en')) } ORDER BY ?l LIMIT 1 } } ``` from the logs: ```10:18:10 INFO Fuseki :: [3] Query = Jan 10 10:18:10 server fuseki-server[98423]: PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#> Jan 10 10:18:10 server fuseki-server[98423]: PREFIX wd: <http://www.wikidata.org/entity/> Jan 10 10:18:10 server fuseki-server[98423]: SELECT ?s ?l { Jan 10 10:18:10 server fuseki-server[98423]: # The ids below correspond in order to: Apache Jena, Semantic Web, RDF, SPARQL, Andy Seaborne Jan 10 10:18:10 server fuseki-server[98423]: VALUES ?s { wd:Q1686799 wd:Q54837 wd:Q54872 wd:Q54871 wd:Q108379795 } Jan 10 10:18:10 server fuseki-server[98423]: Jan 10 10:18:10 server fuseki-server[98423]: SERVICE <cache:loop:bulk+5:https://query.wikidata.org/sparql> { Jan 10 10:18:10 server fuseki-server[98423]: SELECT ?l { Jan 10 10:18:10 server fuseki-server[98423]: ?s rdfs:label ?l Jan 10 10:18:10 server fuseki-server[98423]: FILTER(langMatches(lang(?l), 'en')) Jan 10 10:18:10 server fuseki-server[98423]: } ORDER BY ?l LIMIT 1 Jan 10 10:18:10 server fuseki-server[98423]: } Jan 10 10:18:10 server fuseki-server[98423]: } Jan 10 10:18:10 server fuseki-server[98423]: 10:18:10 INFO QueryIterServiceBulk :: Schedule for current batch: Jan 10 10:18:10 server fuseki-server[98423]: 10:18:10 INFO QueryIterServiceBulk :: input 0: [[0..1)=fetch] Jan 10 10:18:10 server fuseki-server[98423]: 10:18:10 INFO BatchQueryRewriter :: Rewritten bulk query: SELECT * Jan 10 10:18:10 server fuseki-server[98423]: WHERE Jan 10 10:18:10 server fuseki-server[98423]: { { { SELECT ?l Jan 10 10:18:10 server fuseki-server[98423]: WHERE Jan 10 10:18:10 server fuseki-server[98423]: { ?s <http://www.w3.org/2000/01/rdf-schema#label> ?l Jan 10 10:18:10 server fuseki-server[98423]: FILTER langMatches(lang(?l), "en") Jan 10 10:18:10 server fuseki-server[98423]: } Jan 10 10:18:10 server fuseki-server[98423]: ORDER BY ?l Jan 10 10:18:10 server fuseki-server[98423]: LIMIT 1 Jan 10 10:18:10 server fuseki-server[98423]: } Jan 10 10:18:10 server fuseki-server[98423]: BIND(0 AS ?__idx__) Jan 10 10:18:10 server fuseki-server[98423]: } Jan 10 10:18:10 server fuseki-server[98423]: UNION Jan 10 10:18:10 server fuseki-server[98423]: { BIND(1000000000 AS ?__idx__) } ``` <img width="1915" alt="fetching-data-failed" src="https://github.com/apache/jena/assets/5328572/c49efd80-0f35-4ace-b3b1-cc4bc4f3ef6b";> -- This is an automated message from the Apache Git Service.
