Hoi,

Two things, not everybody has the capacity to run an instance of the toolkit. When there are other reasons as well for needing a toolkit than query does not cope, it makes sense to have instances of toolkit on labs where queries like this can be run.

Your response is technical and seriously, query is a tool and it should function for people. When the tool is not good enough fix it. You cannot expect people to engage in the toolkit because most queries are community incidentals and not part of a scientific endeavour.

Thanks,

As a starting note, I don't think extracting 1M triples may be the best
way to use query service. If you need to do processing that returns such
big result sets - in millions - maybe processing the dump - e.g. with
wikidata toolkit at https://github.com/Wikidata/Wikidata-Toolkit - would
be better idea?

It may be some kind of timeout because of the quantity of the data being
sent. How long does such request take?
