Hi there
I am running Fuseki2 within Tomcat and I'm looking for a way to configure
Fuseki to limit the number of rows returned by a query. For example, to
prevent a rogue query such as
SELECT * WHERE {?s ?v ?o}
from being executed to completion.
I've imposed a maximum timeout via
ja:context [ ja:cxtName "arq:queryTimeout" ; ja:cxtValue "60000" ] ;
in config.ttl and also in the individual <dataset>.ttl files, but this does
not seem to prevent the above query from locking up the server.
I've looked through the documentation at
https://jena.apache.org/documentation/fuseki2/fuseki-configuration.html
https://jena.apache.org/documentation/serving_data/#fuseki-configuration-file
https://github.com/apache/jena/tree/master/jena-fuseki2/examples
but I've not found the right config option.
Is this possible, or will I need to modify the source code to add a LIMIT n
if this is not specified in the original query?
Many thanks
Phil
