Elie Roux commented on JENA-1825: --------------------------------- yes, the ticket is about allowing users to do that on a query basis in Fuseki, but I understand it not a small change > disabling some optimizations > ---------------------------- > > Key: JENA-1825 > URL: https://issues.apache.org/jira/browse/JENA-1825 > Project: Apache Jena > Issue Type: Improvement > Components: ARQ > Affects Versions: Jena 3.14.0 > Reporter: Elie Roux > Priority: Minor > > It would be useful to have a mechanism to disable some optimizations in > SPARQL. The reason is that sometimes optimizations hinder performances. For > instance FILTERs with long INs result in large unions which are less > performant than a filter on a small dataset. This really depends on the > queries but can have a big impact. > See also https://github.com/w3c/sparql-12/issues/105 -- This message was sent by Atlassian Jira (v8.3.4#803005)
