Halyard is powerful distributed triplestore, instantly answering majority of SPARQL queries, however weak in some complex operations (like ORDER BY and GROUP BY) and complicated to implement a custom code...
If I configure a repository with Push, the performance of the SPARQL query is extremely slow and might not return within timeout. If I create the same repository but with...
The easiest way to demonstrate this is to set HalyardTupleExprEvaluation.MAX_QUEUE_SIZE = 1 then try to evaluate "ASK {}". HalyardTupleExprEvaluation.evaluateTupleExpr(root.pipe, expr, bindings) needs to be called on a background thread.
This is a clone of the RDF4J issue that also needs to be fixed in Halyard: https://github.com/eclipse/rdf4j/issues/1405 Several tests in HalyardComplexSPARQLQueryTest have to be skipped due to the issue.
