I have a query `g.V().has("USERID","userid","007").properties()`, but the properties and edges of vertex are all stored in table edgestore,
so programs need to query edgestore and get every property and edge from cassandra and judge whether it is property or edge and then filter edge.
so if I want `g.V().has("USERID","userid","007").both().both()`, I am just meant to query 2 degree of 007, but in fact, get 3 degrees, it's expensive, is this a bug?
