Hi,I just noticed that BlazeGraph takes an undue amount of time for a rather simple type of queries. The following times out:
SELECT ?item ?itemLabel WHERE { ?item wdt:P31 [] SERVICE wikibase:label { bd:serviceParam wikibase:language "en". } } LIMIT 10 Manually forcing a specific query plan makes the query work in <200ms: SELECT ?item ?itemLabel WHERE { { SELECT * WHERE { ?item wdt:P31 [] } LIMIT 10 } SERVICE wikibase:label { bd:serviceParam wikibase:language "en". } }But of course the original query should normally be streaming and not depend on any such smartness to push LIMIT inwards.
Cheers, Markus
