How to remove mutiple edges in gremlin query

I created a edge called "created" between User vertex and Event vertex

 user1(8312) ---created---> event1(1234)

 user1(8312) ---created---> event2(4567)

 user1(8312) ---created---> event3(7890)

I can delete one edge at a time,but if I want to delete mutiple edges have to loop though and hit multple db calls.Is there any way to delete mutiple edges at once.

If you want to drop edges between multiple vertices then you could do something like this:

gremlin> g = TinkerFactory.createModern().traversal()
==>graphtraversalsource[tinkergraph[vertices:6 edges:6], standard]
gremlin> g.V(1).outE()
==>e[9][1-created->3]
==>e[7][1-knows->2]
==>e[8][1-knows->4]
gremlin> g.V(1).outE().where(inV().hasId(within(2,3))).drop()
gremlin> g.V(1).outE()
==>e[8][1-knows->4]

You can read more about this in Gremlin Recipes.

I am not sure how you remove the edges, but if you simply want to remove all outgoing created edges from the vertex with the ID 8312, then this should work:

g.V(8312).outE('created').drop().iterate()
