I have a question to the graph definition in arangodb. It is a very simple scenario, but i could not find a good solution. I create a graph with vertex collections A,B,C,D. I create an edge collection E. In edge definition I define (E, [A,B], [C,D]). Now i just want to delete vertex collection D. The only way I found is to use _graps collection to find out which vertex collections are connected with E edge and to rebuild the edge definition without D. Only then D will be moved to orphand collections and can be removed with _removeVertexCollection. Looks really dirty.
Thank you, Andrey
