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?
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
You can use :
g.V().hasId(vertexId).drop()
In the hasId method pass the id of the vertex you want to delete
