Very fast SPARQL Engine, which can handle very large knowledge graphs like the complete Wikidata, offers context-sensitive autocompletion for SPARQL queries, and allows combination with text search. It's faster than engines like Blazegraph or Virtuoso, especially for queries involving large result sets.

confusing messages about "parallel-parsing" : true setting #1600
I'm trying to load Wikidata using the wikidata.settings.json file in the current version of QLever. I'm seeing some confusing messages when the load starts:
2024-11-05 08:46:58.294 - INFO: QLever IndexBuilder, compiled on Mon Nov 4 07:47:39 PM EST 2024 using git hash e52848

Should the settings file be changed? In any case, it seems weird to have QLever produce a message about the setting that kind of indicates that the setting works and later say that it won't work.
