How can I delete a Vertex in Gremlin Server Titan 1.0

Question

I'm using Titan 1.0 Version and Gremlin Server with REST Api for creating and updating Vertex details. How can I delete the vertex using vertexId?

Answer 1

you can use drop property to delete a vertex like :

g.V(vertexId).drop()

you will find more details about drop property on following link :

TinkerPop3 Documentation

Springe

g.V(vertexId).next().remove() will also do the trick. If you have the vertex already then simply v.remove(). Any of the 3 will serve. – Stereotaxis

Please note that g.V(vertexId).drop() without iterating the result will only work in Gremlin console that iterates results automatically. In a Java program, to actually trigger the removal, iteration needs to be requested like this: g.V(vertexId).drop().iterate() – Orizaba

Also, if the Vertex instance you have is a ReferenceVertex (which seems to be the case when you are working via a remote connection), v.remove() will not work at all as removal is not supported for ReferenceVertex. – Orizaba

Answer 2

You can use :

 g.V().hasId(vertexId).drop()

In the hasId method pass the id of the vertex you want to delete
