We've noticed that for some queries the SPARQL Query Validator in Fuseki will generate different algebra versus the query algebra we see when processing it within our query engine.
The particular example we see is certain queries use join (OpJoin) in the validator output but sequence (OpSequence) in the actual query engine. I haven't dived into the code yet to take a look at what's going on but can anyone tell me quickly whether this is an expected behaviour? e.g. does the validator only show the unoptimised algebra Cheers, Rob
