Changing the subject a bit:
I am surprised to see how many SPARQL requests go to the endpoint when
performing a ShEx validation with the shex-simple Toolforge tool. They
are all very simple and quickly complete. For each Wikidata item tested,
one of our tests [1] requests tens of times. That is, testing 100
Wikidata items may yield thousands of requests to the endpoint in rapid
succession.
I suppose that given the simple SPARQL queries, these kinds of requests
might not load WDQS very much.
