Description
The aggregate could collect identifiers of the TopoGeometry objects by topology and layer and in the final function select the extent of the components. It'd need to be tested if it's really going to be faster as it's still a lot of queries in the db, but the idea is to improve the cost of such operation by avoiding to construct the Geometry from the TopoGeometry.
