Update edge property value using gremlin scala in titan + cassandra DB

Question

I am trying to update an edge property value of outgoing Edges (outE) using gremlin scala.

Environment: Titan + Cassandra

graph.V().outE().properties("Id","100").iterate()

Above is not working. Is there any other way to update the edge property value.

Answer 1

You have a minor error. Your traversal is doing a lookup. To add the property to all the edges you do the following:

graph.traversal().V().outE().property("Id","100").iterate();

property mutates. properties does a lookup. More info here
