Andy Seaborne commented on JENA-619:
------------------------------------
Theer is an ARQ symbol optFilterPlacementBGP that controls whether the
high-level filter placement considers pushing filters into BGPs or not. The
default is "true", means filter do get pushed into BGPs. TDB sets this to off
and then does filter placement in a BGP itself when working in NodeId patterns
later.
The in-memory query (StageGeneratorGeneric) should do likewise - reorder BGPs
then place filters.
> Optimization of filter placement and BGP reordering.
