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.

Solution

  • 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]
