Qlever is an alternative SPARQL endpoint for Wikidata data. The updates are not real time ; but it is considerably faster than WDQS. It would unlock using integraality for datasets that are too big/complex for WDQS.
Open questions: would this be only for the dashboard-building, or also for the looking-glass (aka queries endpoint).

| Resolved | JeanFred | T385749 Support qlever endpoint for integraality | |||
| Resolved | JeanFred | T420247 Function "<http://wikiba.se/ontology#isSomeValue>" is currently not supported by QLever. |
And since qlever support Wikimedia Commons, this could unlock T294893: integraality for Structured Data on Commons?
Qlever is approaching being able to support real-time updates, and is being more widely used by various wikidata-related initiatives as well as those involving larger datasets. This would be excellent.

This is now done, as present for Wikidata’s 13th birthday :)
See example at https://www.wikidata.org/wiki/Wikidata:WikiProject_sum_of_all_paintings/Property_statistics/Sandbox
I have a couple of fixes to do, but this is good as done :)
