    Difference between Jena/Joseki and sem_match

    M.E.R. van Boxel-Oracle

      Dear All,

       

      There are different ways for us fire SPARQL queries into the Spatial and Graph extension. The two methods we are using at this moment are Jena/Joseki and sem_match. Where Jena/Joseki is an end-point on a WLS.

       

      The same SPARQL queries fired either by sem_match or Jena/Joseki do not result in the same execution plan. We are wondering if it is possible in anyway to let Jena/Joseki use the same rules as sem_match to receive the same execution plan.

       

      If there is not such a method, is there than a plan to bring these two optimizers closer together?

       

      Kind regards,

      Max
