Dear all,
I have a (relatively large) dataset in Fuseki (default optimization
settings) which I attached the relevant triples. The following query
takes around 160ms (according to Fuseki logs):
construct {
?res ?resp ?reso .
}
where {
{
bdr:G844 ?rel ?res .
?res a bdo:Place .
?res ?resp ?reso .
}
}
It's not great (at all) but I can live with it, the problem is that if
I add this filter:
FILTER (?resp = skos:altLabel || ?resp = skos:prefLabel || ?resp =
skos:placeEvent || ?resp = bdo:placeLat || ?resp = bdo:placeLong ||
?resp = bdo:placeType || ?resp = bdo:placeLocatedIn || ?resp =
owl:sameAs || ?resp = tmp:entityScore)
which despite its length is quite simple, then the Fuseki logs
indicate 1200ms!! I reproduced it at least 20 times.
Attached are the complete slow and fast queries. Is there an obvious
error in my query or it a performance issue from Fuseki? If so I can
report it on JIRA.
Best,

Elie
