Andy Seaborne resolved JENA-294. -------------------------------- Resolution: Fixed Fix Version/s: ARQ 2.9.4 Assignee: Andy Seaborne > TransformFilterEquality does not handle starting OPTIONAL well > -------------------------------------------------------------- > > Key: JENA-294 > URL: https://issues.apache.org/jira/browse/JENA-294 > Project: Apache Jena > Issue Type: Improvement > Components: ARQ > Affects Versions: Jena 2.7.4 > Reporter: Simon Helsen > Assignee: Andy Seaborne > Fix For: ARQ 2.9.4 > > Attachments: jena-294-afs-1.patch, patch.txt, patch.txt, > test-filter-equality.zip > > > There was one other case where our tests were stuck on a very slow query > execution because transformFilterEquality failed to optimize. The problem is > that the optimizer gives up whenever the WHERE clause starts with an OPTIONAL > clause. The reason is that the generated algebraic formula starts with a > TableUnit and this is not handled correctly. > I have attached a patch which fixes the problem -- This message is automatically generated by JIRA.
