So my question is, after traversal, I have got several paths, a path looks like node1-edge1-node2-edge2-node3, now I want to attach a property called ‘frequency’ to this specific path, and its values equals edge1’s ‘frequency’ property value, how should I do it? Or it cannot be done using Gremlin, and I have to use Java?

I tried something like this:

    g.E().has('length', gt(1)).as('edge1')
    .outV().as('node1')
    .select('edge1')
    .inV().as('node2')
    .outE().as('edge2').where('edge1', eq('edge2').by('id'))
    .inV().as('node3')
    .path()
