No it does not support bi directional edges as of now.

So the question comes to does graphframes support bidirectional relationship natively with
only one edge?

Generally that would be the approach.
But since you have effectively double the number of edges this will likely affect the scale
your job will run.

Hi,
To represent a bidirectional relationship, one solution is to insert two edges for the vertices
pair, my question is do the algorithms of graphframes still work when we doing this.

Thanks
