It would be absolutely fantastic if records inside the base table of a oqgraph queried table could be filtered before applying the graph storage engine logic.
I've tried a few work around methods including targeting the oqgraph creation statement at temp tables and views, these create fine, but when queried give the table not found error. This could also be very useful.
One workaround which is working, not ideal though, is a transaction based delete on the base table data before running the oqgraph table query:
Use case here is a routing query /system for a game where solar systems can have may jump gates to other solar systems. OQGRAPH's performance in this area is unmatched at milliseconds for a routed chain of 41 systems having an average of 4 different possible routes each.
