Titan: Know if a new vertex or edge was created

Question

Does titan provide RDBMS trigger kind of thing that will be triggered whenever a new vertex or edge is added to the graph?

How will I know that a new vertex or edge was added to the graph?

Answer 1

Titan does not have a way to deal with that natively. You could, however, use EventGraph which is a graph wrapper over blueprints:

https://github.com/tinkerpop/blueprints/wiki/Event-Implementation

EvenGraph will pop off events to a listener that you write to gather the events.

EDIT: The above answer applies to TinkerPop 2.x and Titan 0.5.x and earlier. In Titan 1.x and TinkerPop 3.x one would rely on EventStrategy or Titan's Transaction Log.
