Hi Paul,
it is possible to configure a timeout for each SPARQL query, see Section
"Service 3" [1]:
<#dataset> rdf:type tdb:DatasetTDB ;
tdb:location "DB" ;
# Query timeout on this dataset (1s, 1000 milliseconds)
ja:context [ ja:cxtName "arq:queryTimeout" ; ja:cxtValue "1000" ] ;
[...]
.
Fuseki uses Jetty, therefore, in theory, one could benefit from Jetty features
to protect against too aggressive users, such as:
- http://wiki.eclipse.org/Jetty/Reference/DoSFilter
- http://wiki.eclipse.org/Jetty/Reference/QoSFilter
Others put Fuseki behind a web server|proxy anyway and they do this sort of
things elsewhere.
