How to traverse a connected component and return the path travelled

[Shaoor Jan]

Hi, 

I'm new to Gremlin and would appreciate some help. 

I want to traverse a connected component starting from a node and return the path. I need the path so that I can visualize the graph in AWS Neptune. 

The solutions present online do not return a path.  

The screenshot shows the end result I want to get. 

Thanks!

I have no Neptune workbench available to experiment with, but I guess the following should work:

g.V().has('my_prop', 'my_value').
    emit(cyclicPath().or().not(both())).repeat(
        __.where(without('a')).aggregate('a').both()).until(cyclicPath()
    ).path()

This is an adaptation of the query in https://tinkerpop.apache.org/docs/current/recipes/#_small_graph_traversals.

Best wishes,   Marc

Hi Marc, 

Thank you! that was helpful. 

I used a similar query. I posted it below in case it might be helpful for someone. 

g.V().has('my_label', 'my_prop', 'my_value')

     .until(cyclicPath().or().hasLabel('my_label'))        //// I wanted to if I hit a node with a particular label 

     .repeat(bothE().otherV().simplePath()).emit()

     .path()

Thank You!
